English
Noun
airlines
- Plural of airline
An airline provides
air transport
services for
passengers or
freight, generally with a
recognized operating certificate or license. Airlines
lease or own their
aircraft with which to supply
these services and may form
partnerships or
alliances
with other airlines for mutual benefit.
Airlines vary from those with a single airplane
carrying mail or cargo, through full-service international airlines
operating many hundreds of airplanes. Airline services can be
categorized as being intercontinental, intracontinental, or
domestic and may be operated as scheduled services or
charters.
History
The First Airlines
DELAG, Deutsche
Luftschiffahrts-Aktiengesellschaft (
German:
acronym for "German Airship Transport Corporation") was the
world's first airline. It was founded on
November 16,
1909 with
government assistance, and operated airships manufactured by
Zeppelin
Corporation. Its headquarters were in
Frankfurt. (Note:
Americans, such as
Rufus Porter
and
Frederick
Marriott, attempted to start airlines in the mid-19th century,
focusing on the New York-California route. Those attempts foundered
due to such mishaps as the aircraft catching fire and the aircraft
being ripped apart by spectators.) The five
oldest non-dirigible airlines that still exist are Netherland's
KLM, Colombia's
Avianca,
Australia's
Qantas, Mexico's
Mexicana
and Czech Republic's
Czech
Airlines.
U.S. Airline Industry
Early Development
Tony Jannus
conducted the United States' first scheduled commercial airline
flight on 1 January 1914 for the Saint Petersburg-routes,
Braniff
Airways,
American
Airlines,
Delta Air
Lines,
United
Airlines (originally a division of
Boeing),
Trans
World Airlines,
Northwest
Airlines, and
Eastern
Air Lines, to name a few.
Passenger service during the early 1920s was
sporadic: most airlines at the time were focused on carrying bags
of mail. In 1925, however, the
Ford
Motor Company bought out the
Stout
Aircraft Company and began construction of the all-metal
Ford
Trimotor, which became the first successful American airliner.
With a 12-passenger capacity, the Trimotor made passenger service
potentially profitable. Air service was seen as a supplement to
rail
service in the American transportation network.
At the same time,
Juan Trippe
began a crusade to create an air network that would link America to
the world, and he achieved this goal through his airline,
Pan American World Airways, with a fleet of flying boats that
linked
Los
Angeles to
Shanghai and
Boston
to
London.
Pan Am and Northwest Airways (which began flights to Canada in the
1920s) were the only U.S. airlines to go international before the
1940s.
With the introduction of the
Boeing 247 and
Douglas
DC-3 in the 1930s, the U.S. airline industry was generally
profitable, even during the
Great
Depression. This trend continued until the beginning of
World
War II.
Development since 1945
As governments met to set the
standards and scope for an emergent civil air industry toward the
end of the war, it was no surprise that the U.S. took a position of
maximum operating freedom. After all, U.S. airline companies were
not devastated by the war, as European companies and the few Asian
companies had been. This preference for "open skies" operating
regimes continues, within limitations, to this day.
World War II, like World War I, brought new life
to the airline industry. Many airlines in the Allied countries were
flush from lease contracts to the military, and foresaw a future
explosive demand for civil air transport, for both passengers and
cargo. They were eager to invest in the newly emerging flagships of
air travel such as the
Boeing
Stratocruiser,
Lockheed
Constellation, and
Douglas
DC-6. Most of these new aircraft were based on American bombers
such as the
B-29, which had
spearheaded research into new technologies such as
pressurization. Most
offered increased efficiency from both added speed and greater
payload.
In the 1950s, the
De
Havilland Comet,
Boeing 707,
Douglas
DC-8, and
Sud
Aviation Caravelle became the first flagships of the Jet Age in
the West, while the
Soviet Union
bloc countered with the
Tupolev
Tu-104 and
Tupolev
Tu-124 in the fleets of state-owned carriers such as
Aeroflot and
Interflug. The
Vickers
Viscount and
Lockheed
L-188 Electra inaugurated turboprop transport.
The next big boost for the airlines would come in
the 1970s, when the
Boeing 747,
McDonnell
Douglas DC-10, and
Lockheed
L-1011 inaugurated widebody ("jumbo jet") service, which is
still the standard in international travel. The
Tupolev
Tu-144 and its Western counterpart,
Concorde, made
supersonic travel a reality. In 1972,
Airbus began
producing Europe's most commercially successful line of airliners
to date. The added efficiencies for these aircraft were often not
in speed, but in passenger capacity, payload, and range.
1978's U.S.
airline
industry deregulation lowered barriers for new airlines. In
this period, new start-ups entered during downturns in the normal
8-10 year business cycle. At that time, they find aircraft, are
financed, contract hangar and maintenance services, train new
employees, and recruit laid off staff from other airlines.
As the business cycle returned to normalcy, major
airlines dominated their routes through aggressive pricing and
additional capacity offerings, often swamping new startups. Only
America
West Airlines (which has since merged with US Airways) remained
a significant survivor from this new entrant era, as dozens, even
hundreds, have gone under.
In many ways, the biggest winner in the
deregulated environment was the air passenger. Indeed, the U.S.
witnessed an explosive growth in demand for air travel, as many
millions who had never or rarely flown before became regular
fliers, even joining
frequent
flyer loyalty programs and receiving free flights and other
benefits from their flying. New services and higher frequencies
meant that business fliers could fly to another city, do business,
and return the same day, for almost any point in the country. Air
travel's advantages put intercity bus lines under pressure, and
most have withered away.
By the 1980s, almost half of the total flying in
the world took place in the U.S., and today the domestic industry
operates over 10,000 daily departures nationwide.
Toward the end of the century, a new style of
low
cost airline emerged, offering a no-frills product at a lower
price.
Southwest
Airlines,
JetBlue,
AirTran
Airways,
Skybus
Airlines and other low-cost carriers began to represent a
serious challenge to the so-called "legacy airlines", as did their
low-cost counterparts in Europe, Canada, and Asia. Their commercial
viability represented a serious competitive threat to the legacy
carriers. However, of these, ATA and Skybus have since ceased
operations.
Thus the last 50 years of the airline industry
have varied from reasonably profitable, to devastatingly depressed.
As the first major market to deregulate the industry in 1978, U.S.
airlines have experienced more turbulence than almost any other
country or region. Today, almost every single
legacy
carrier except for
American
Airlines has operated under Chapter 11 bankruptcy provisions or
have gone out of business.
European Airline Industry
The first countries in Europe to
embrace air transport were
Finland,
France,
Germany, the
Netherlands and
the
United
Kingdom.
KLM, the oldest carrier
still operating under its original name, was founded in 1919. The
first flight (operated on behalf of KLM by
Aircraft Transport and Travel) transported two English
passengers to
Schiphol,
Amsterdam from
London in
1920. Like other major European airlines of the time (see France
and the UK below), KLM's early growth depended heavily on the needs
to service links with far-flung colonial possessions (
Dutch
Indies). It is only after the loss of the
Dutch Empire
that
KLM found
itself based at a small country with few potential passengers,
depending heavily on transfer traffic, and was one of the first to
introduce the hub-system to facilitate easy connections.
France began an air mail service to
Morocco in 1919
that was bought out in 1927, renamed
Aéropostale,
and injected with capital to become a major international carrier.
In 1933, Aéropostale went
bankrupt, was
nationalized and merged with several other airlines into what
became
Air
France.
In Finland, the charter establishing Aero O/Y
(now
Finnair, one of the
oldest still-operating airlines in the world) was signed in the
city of
Helsinki on
12
September,
1923.
Junkers F
13 D-335 became the first aircraft of the company, when Aero
took delivery of it on
14 March,
1924. The
first flight was between Helsinki and
Tallinn, capital of
Estonia,
and it took place on
20 March 1924,
one week later.
Germany's
Lufthansa began
in 1926. Lufthansa, unlike most other airlines at the time, became
a major investor in airlines outside of Europe, providing capital
to
Varig and
Avianca.
German airliners built by
Junkers,
Dornier, and
Fokker were
the most advanced in the world at the time. The peak of German air
travel came in the mid-1930s, when
Nazi propaganda
ministers approved the start of commercial
zeppelin service: the big
airships were a symbol
of industrial might, but the fact that they used flammable hydrogen
gas raised safety concerns that culminated with the
Hindenburg
disaster of 1937. The reason they used
hydrogen instead of the
not-flammable
helium gas
was a United States military embargo on helium.
The
British
company
Aircraft Transport and Travel commenced a London to Paris
service on
25 August
1919, this was
the world's first regular international flight. The
United
Kingdom's
flag carrier
during this period was
Imperial
Airways, which became
BOAC (British Overseas
Airways Co.) in 1939. Imperial Airways used huge
Handley-Page
biplanes for routes
between
London, the
Middle East,
and
India:
images of Imperial aircraft in the middle of the
Rub'al
Khali, being maintained by
Bedouins, are among
the most famous pictures from the heyday of the
British
Empire.
Deregulation
Deregulation of the
European
Union airspace in the early 1990's has had substantial effect
on structure of the industry there. The shift towards 'budget'
airlines on shorter routes has been significant. Airlines such as
Easyjet and
Ryanair
have grown at the expense of the traditional national
airlines.
There has also been a trend for these national
airlines themselves to be privatised such as has occurred for
Aer
Lingus (Ireland) and
British
Airways. Other national airlines, including Italy's
Alitalia, have
suffered - particularly with the rapid increase of oil prices in
early 2008.
Latin American Airline Industry
Along the first countries to have regular
airlines in Latin America were
Chile with
LAN Chile
(today
LAN
Airlines), Colombia with
Avianca, Brazil
with
Varig
and
TACA as a
bound of several airlines of Central American countries (Honduras,
El Salvador, Costa Rica, Guatemala and Nicaragua). All the previous
airlines started regular operations before World War II.
Aeromexico is
also in service since 1934, but was initially called Aeronaves de
México. The same situation happened with other regional airlines,
such as Aerolineas Argentinas. All of these
airlines are still in
service.
The air travel market has evolved rapidly over
recent years in
Latin
America. Some industy estimations over 2000 new aircraft will
begin service over the next five years in this region.
These airlines serve domestic flights within
their countries, as well as connections within Latin America and
also overseas flights to North America, Europe, Australia, Africa
and Asia.
Just one airline, LAN (Latin American Networks)
has international subsidiaries:
Chile as the central
operation along with Peru, Ecuador, Argentina and some operations
in the Dominican Republic.
The main
hubs in Latin America are
Sao Paulo in
Brazil,
Lima
in Peru,
Mexico City
in Mexico and
Santiago in
Chile.
Asian Airline Industry
Some of the first countries in Asia to embrace
air transport were
India,
Hong Kong,
Indonesia,
Malaysia
and the
Philippines.
The one of the first countries in Asia to embrace
air transport was the
Philippines.
Philippine
Airlines was founded on
February 26,
1941, making
it Asia's oldest carrier and the oldest operating under its current
name. The airline was started by a group of businessmen led by
Andres Soriano, hailed as one of the Philippines' leading
industrialists at the time. The airline’s first flight was made on
March
15,
1941
with a single
Beech Model
18 NPC-54 aircraft, which started its daily services between
Manila (from
Nielson
Field) and
Baguio, later to
expand with larger aircraft such as the DC-3 and Vickers Viscount.
Notably
Philippine
Airlines leased
Japan
Airlines their first aircraft, a DC-3 named "Kinsei". On
July 31,
1946, a
chartered
Philippine
Airlines DC-4 ferried 40
American servicemen to
Oakland,
California from
Nielson Airport in
Makati City
with stops in
Guam,
Wake Island,
Johnston
Atoll and
Honolulu,
Hawaii, making PAL
the first Asian airline to cross the
Pacific
Ocean. A regular service between
Manila and
San
Francisco was started in December. It was during this year that
the airline was designated as the
Philippines
flag
carrier.
Another airline company to begin early operations
was
Air
India, which had its beginning as Tata Airlines in
1932, a division of
Tata Sons Ltd. (now
Tata Group) by
India's leading industrialist
JRD Tata. On
October
15,
1932,
J. R. D. Tata himself flew a single engined
De
Havilland Puss Moth carrying air mail (postal mail of
Imperial
Airways) from
Karachi to
Bombay via
Ahmedabad. The
aircraft continued to
Madras via Bellary
piloted by
Royal Air
Force pilot Nevill Vincent.
Following the end of World War II, regular
commercial service was restored in India and Tata Airlines became a
public limited company on
29 July 1946 under the name
Air India. After the Independence of India, 49% of the airline was
acquired by the Government of India. In return, the airline was
granted status to operate international services from India as the
designated flag carrier under the name Air India
International.
Neighbouring countries also soon embraced air
transport, notably with the beginning of a new nation, Pakistan
began Orient Airways Ltd (
Pakistan
International Airlines),
Cathay
Pacific founded in 1946,
Singapore
Airlines and
Malaysian
Airlines in 1947 (as
Malayan
Airways),
Garuda
Indonesia in 1949,
Japan
Airlines in 1951, and
Korean Air in
1962. With the outbreak of World War Two, the airline presence in
Asia came to a relative halt, with many new flag carriers donating
their aircraft for military aid and other uses.
Regulatory considerations
National
Many countries have
national
airlines that the government owns and operates. Fully private
airlines are subject to a great deal of government regulation for
economic, political, and safety concerns. For instance, the
government often intervenes to halt airline labor actions in order
to protect the free flow of people, communications, and goods
between different regions without compromising safety.
The United States, Australia, and to a lesser
extent Brazil, Mexico, the United Kingdom and Japan have
"deregulated" their airlines. In the past, these governments
dictated airfares, route networks, and other operational
requirements for each airline. Since deregulation, airlines have
been largely free to negotiate their own operating arrangements
with different airports, enter and exit routes easily, and to levy
airfares and supply flights according to market demand.
The entry barriers for new airlines are lower in
a deregulated market, and so the U.S. has seen hundreds of airlines
start up (sometimes for only a brief operating period). This has
produced far greater competition than before deregulation in most
markets, and average fares tend to drop 20% or more. The added
competition, together with pricing freedom, means that new entrants
often take market share with highly reduced rates that, to a
limited degree, full service airlines must match. This is a major
constraint on profitability for established carriers, which tend to
have a higher cost base.
As a result, profitability in a deregulated
market is uneven for most airlines. These forces have caused some
major airlines to go out of business, in addition to most of the
poorly established new entrants.
International
Groups such as the
International Civil Aviation Organization establish worldwide
standards for safety and other vital concerns. Most international
air traffic is regulated by bilateral agreements between countries,
which designate specific carriers to operate on specific routes.
The model of such an agreement was the
Bermuda
Agreement between the US and UK following World War II, which
designated airports to be used for transatlantic flights and gave
each government the authority to nominate carriers to operate
routes.
Bilateral agreements are based on the "
freedoms
of the air," a group of generalized traffic rights ranging from
the freedom to overfly a country to the freedom to provide domestic
flights within a country (a very rarely granted right known as
cabotage). Most
agreements permit airlines to fly from their home country to
designated airports in the other country: some also extend the
freedom to provide continuing service to a third country, or to
another destination in the other country while carrying passengers
from overseas.
In the 1990s, "
open skies"
agreements became more common. These agreements take many of these
regulatory powers from state governments and open up international
routes to further competition. Open skies agreements have met some
criticism, particularly within the
European
Union, whose airlines would be at a comparative disadvantage
with the United States' because of cabotage restrictions.
Economic considerations
Historically, air travel has
survived largely through state support, whether in the form of
equity or subsidies. The airline industry as a whole has made a
cumulative loss during its 120-year history, once the costs include
subsidies for aircraft development and airport construction.
One argument is that
positive
externalities, such as higher growth due to global mobility,
outweigh the microeconomic losses and justify continuing government
intervention. A historically high level of government intervention
in the airline industry can be seen as part of a wider political
consensus on strategic forms of transport, such as
highways and
railways, both of which receive
public funding in most parts of the world. Profitability is likely
to improve in the future as privatization continues and more
competitive low-cost carriers proliferate.
Although many countries continue to operate
state-owned or parastatal airlines, many large airlines today are
privately owned and are therefore governed by microeconomic
principles in order to maximize shareholder profit.
Ticket revenue
Airlines assign prices to their services in
an attempt to maximize profitability. The pricing of airline
tickets has become increasingly complicated over the years and is
now largely determined by computerized
yield
management systems.
Because of the complications in scheduling
flights and maintaining profitability, airlines have many loopholes
that can be used by the knowledgeable traveler. Many of these
airfare secrets are becoming more and more known to the general
public, so airlines are forced to make constant adjustments.
Most airlines use differentiated pricing, a form
of
price
discrimination, in order to sell air services at varying prices
simultaneously to different segments. Factors influencing the price
include the days remaining until departure, the booked load factor,
the forecast of total demand by price point, competitive pricing in
force, and variations by day of week of departure and by time of
day. Carriers often accomplish this by dividing each cabin of the
aircraft (first, business and economy) into a number of
travel
classes for pricing purposes.
A complicating factor is that of
origin-destination control ("O&D control"). Someone purchasing
a ticket from Melbourne to Sydney (as an example) for $200 (AUD) is
competing with someone else who wants to fly Melbourne to Los
Angeles through Sydney on the same flight, and who is willing to
pay $1400 (AUD). Should the airline prefer the $1400 passenger, or
the $200 passenger plus a possible Sydney-Los Angeles passenger
willing to pay $1300? Airlines have to make hundreds of thousands
of similar pricing decisions daily.
The advent of advanced computerized reservations
systems in the late 1970s, most notably
Sabre,
allowed airlines to easily perform
cost-benefit
analyses on different pricing structures, leading to almost
perfect price discrimination in some cases (that is, filling each
seat on an aircraft at the highest price that can be charged
without driving the consumer elsewhere).
The intense nature of airfare pricing has led to
the term "
fare war" to
describe efforts by airlines to undercut other airlines on
competitive routes. Through computers, new airfares can be
published quickly and efficiently to the airlines' sales channels.
For this purpose the airlines use the
Airline Tariff Publishing Company (ATPCO), who distribute
latest fares for more than 500 airlines to
Computer Reservation Systems across the world.
The extent of these pricing phenomena is
strongest in "legacy" carriers. In contrast, low fare carriers
usually offer preannounced and simplified price structure, and
sometimes quote prices for each leg of a trip separately.
Computers also allow airlines to predict, with
some accuracy, how many passengers will actually fly after making a
reservation to fly. This allows airlines to overbook their flights
enough to fill the aircraft while accounting for "no-shows," but
not enough (in most cases) to force paying passengers off the
aircraft for lack of seats. Since an average of ⅓ of all seats are
flown empty, stimulative pricing for low demand flights coupled
with overbooking on high demand flights can help reduce this
figure.
Operating costs
Full-service airlines have a high level of
fixed and operating costs in order to establish and maintain air
services: labor, fuel, airplanes, engines, spares and parts, IT
services and networks, airport equipment, airport handling
services, sales distribution, catering, training,
aviation
insurance and other costs. Thus all but a small percentage of
the income from ticket sales is paid out to a wide variety of
external providers or internal cost centers.
Moreover, the industry is structured so that
airlines often act as tax collectors. Airline fuel is untaxed,
however, due to a series of treaties existing between countries.
Ticket prices include a number of fees, taxes, and surcharges they
have little or no control over, and these are passed through to
various providers. Airlines are also responsible for enforcing
government regulations. If airlines carry passengers without proper
documentation on an international flight, they are responsible for
returning them back to the originating country.
Analysis of the 1992-1996 period shows that every
player in the air transport chain is far more profitable than the
airlines, who collect and pass through fees and revenues to them
from ticket sales. While airlines as a whole earned 6% return on
capital employed (2-3.5% less than the cost of capital), airports
earned 10%, catering companies 10-13%, handling companies 11-14%,
aircraft lessors 15%, aircraft manufacturers 16%, and global
distribution companies more than 30%. (Source: Spinetta, 2000,
quoted in Doganis, 2002)
In contrast,
Southwest
Airlines has been the most
profitable of airline
companies since 1970.
The widespread entrance of a new breed of low
cost airlines beginning at the turn of the century has accelerated
the demand that full service carriers control costs. Many of these
low cost companies emulate
Southwest
Airlines in various respects, and like Southwest, they are able
to eke out a consistent profit throughout all phases of the
business cycle.
As a result, a shakeout of airlines is occurring
in the U.S. and elsewhere.
United
Airlines,
US Airways
(twice),
Delta Air
Lines, and
Northwest
Airlines have all declared
Chapter 11
bankruptcy. Some argue that it would be far better for the industry
as a whole if a wave of actual closures were to reduce the number
of "undead" airlines competing with healthy airlines while being
artificially protected from creditors via
bankruptcy law. On the other
hand, some have pointed out that the reduction in capacity would be
short lived given that there would be large quantities of
relatively new aircraft that bankruptcies would want to get rid of
and would re-enter the market either as increased fleets for the
survivors or the basis of cheap planes for new startups.
Where an airline has established an engineering
base at an airport then there may be considerable economic
advantages in using that same airport as a preferred focus (or
"hub") for its scheduled flights.
Assets and financing
Airline financing is quite complex,
since airlines are highly leveraged operations. Not only must they
purchase (or lease) new airliner bodies and engines regularly, they
must make major long-term fleet decisions with the goal of meeting
the demands of their markets while producing a fleet that is
relatively economical to operate and maintain. Compare
Southwest
Airlines and their reliance on a single airplane type (the
Boeing
737 and derivatives), with the now defunct
Eastern
Air Lines which operated 17 different aircraft types, each with
varying pilot, engine, maintenance, and support needs.
A second financial issue is that of
hedging oil and
fuel purchases, which are usually
second only to
labor in
its relative cost to the company. However, with the current high
fuel prices it has become the largest cost to an airline. While
hedging instruments can be expensive, they can easily pay for
themselves many times over in periods of increasing fuel costs,
such as in the 2000-2005 period.
In view of the congestion apparent at many
international
airports,
the ownership of slots at certain airports (the right to take-off
or land an aircraft at a particular time of day or night) has
become a significant tradable asset for many airlines. Clearly
take-off slots at popular times of the day can be critical in
attracting the more profitable business traveler to a given
airline's flight and in establishing a competitive advantage
against a competing airline. If a particular city has two or more
airports, market forces will tend to attract the less profitable
routes, or those on which competition is weakest, to the less
congested airport, where slots are likely to be more available and
therefore cheaper. Other factors, such as surface transport
facilities and onward connections, will also affect the relative
appeal of different airports and some long distance flights may
need to operate from the one with the longest runway.
Airline partnerships
Code sharing
is the most common type of airline partnership; it involves one
airline selling tickets for another airline's flights under its own
airline code. An early example of this was
Japan
Airlines' code sharing partnership with
Aeroflot in the
1960s on flights from
Tokyo to
Moscow: Aeroflot
operated the flights using Aeroflot aircraft, but JAL sold tickets
for the flights as if they were JAL flights. This practice allows
airlines to expand their operations, at least on paper, into parts
of the world where they cannot afford to establish bases or
purchase aircraft. Another example was the
Austrian-
Sabena
partnership on the
Vienna-
Brussels-
New York JFK
route during the late 60's, using a Sabena Boeing 707 with Austrian
colors.
Since airline reservation requests are often made
by city-pair (such as "show me flights from Chicago to
Düsseldorf"), an airline who is able to code share with another
airline for a variety of routes might be able to be listed as
indeed offering a Chicago-Düsseldorf flight. The passenger is
advised however, that Airline 1 operates the flight from say
Chicago to Amsterdam, and Airline 2 operates the continuing flight
(on a different airplane, sometimes from another terminal) to
Düsseldorf. Thus the primary rationale for code sharing is to
expand one's service offerings in city-pair terms so as to increase
sales.
A more recent development is the
airline
alliance, which became prevalent in the 1990s. These alliances
can act as virtual mergers to get around government restrictions.
Groups of airlines such as the
Star
Alliance,
Oneworld, and
SkyTeam
coordinate their passenger service programs (such as lounges and
frequent flyer programs), offer special interline tickets, and
often engage in extensive codesharing (sometimes systemwide). These
are increasingly integrated business combinations-- sometimes
including cross-equity arrangements-- in which products, service
standards, schedules, and airport facilities are standardized and
combined for higher efficiency. One of the first airlines to start
an alliance with another airline was
KLM, who partnered with
Northwest
Airlines. Both airlines later entered the
SkyTeam alliance
after the fusion of KLM and
Air France in
2004.
Often the companies combine IT operations, buy
fuel, or purchase airplanes as a bloc in order to achieve higher
bargaining power. However, the alliances have been most successful
at purchasing invisible supplies and services, such as fuel.
Airlines usually prefer to purchase items visible to their
passengers to differentiate themselves from local competitors. If
an airline's main domestic competitor flies Boeing airliners, then
the airline may prefer to use Airbus aircraft regardless of what
the rest of the alliance chooses.
Environmental impacts
Aircraft engines
emit
noise
pollution, gases and particulate emissions, and contribute to
global
warming and
global
dimming.
Modern
turbofan and
turboprop engines are
considerably more fuel-efficient and less polluting than earlier
models. However, despite this, the rapid growth of
air travel in
recent years contributes to an increase in total pollution
attributable to
aviation, offsetting some of
the reductions achieved by automobiles. In the
EU
greenhouse
gas emissions from aviation increased by 87% between 1990 and
2006.
In the context of climate change and
peak oil, there
is a debate about possible
taxation of air travel and the
inclusion of aviation in an
emissions
trading scheme, with a view to ensuring that the total
external
costs of aviation are taken into account.
The airline industry is responsible for about 11
percent of
greenhouse
gases emitted by the U.S. transportation sector.
Boeing estimates
that biofuels could reduce flight-related greenhouse-gas emissions
by 60 to 80 percent. The solution would be blending algae fuels
with existing jet fuel:
Call signs
Each operator of a scheduled or charter flight
uses a
airline call sign when communicating with airports or air
traffic control centers. Most of these call-signs are derived from
the airline's trade name, but for reasons of history, marketing, or
the need to reduce ambiguity in spoken English (so that pilots do
not mistakenly make navigational decisions based on instructions
issued to a different aircraft), some airlines and air forces use
call-signs less obviously connected with their trading name. For
example, British Airways uses a Speedbird call-sign, named after
the logo of its predecessor,
BOAC, while
America West
used Cactus reflecting that company's home in the state of Arizona
and to differentiate itself from numerous other airlines using
America and West in their call signs.
Airline personnel
The various types of airline personnel
include:
- Flight crews,
responsible for the operation of the aircraft. Flight crew members
include:
- Groundcrew,
responsible for operations at airports. Ground crew members
include:
- Reservations
agents, usually (but not always) at facilities outside the
airport.
Airlines follow a
corporate structure where
each broad area of operations (such as maintenance, flight
operations, and passenger service) is supervised by a vice
president. Larger airlines often appoint vice presidents to oversee
each of the airline's hubs as well. Airlines employ
lawyers to deal with regulatory
procedures and other administrative tasks.
Industry Trends
The pattern of ownership has gone from
government owned or supported to independent, for-profit public
companies. This occurs as regulators permit greater freedom and
non-government ownership, in steps that are usually decades apart.
This pattern is not seen for all airlines in all regions.
The overall trend of demand has been consistently
increasing. In the 1950s and 1960s, annual growth rates of 15% or
more were common. Annual growth of 5-6% persisted through the 1980s
and 1990s. Growth rates are not consistent in all regions, but
countries with a de-regulated airline industry have more
competition and greater pricing freedom. This results in lower
fares and sometimes dramatic spurts in traffic growth. The
U.S.,
Australia,
Canada,
Japan,
Brazil,
Mexico,
India and other
markets exhibit this trend. The industry has been observed to be
cyclical in it's financial performance. Four or five years of poor
earnings precede five or six years of improvement. But
profitability even in the good years is generally low, in the range
of 2-3% net profit after interest and tax. In times of profit,
airlines lease new generations of airplanes and upgrade services in
response to higher demand. Since 1980, the industry has not earned
back the cost of capital during the best of times. Conversely, in
bad times losses can be dramatically worse.
Warren
Buffett once said that despite all the money that has been
invested in all airlines, the net profit is less than zero. He
believes it is one of the hardest businesses to manage.
As in many mature industries, consolidation is a
trend. Airline groupings may consist of limited bilateral
partnerships, long-term, multi-faceted alliances between carriers,
equity arrangements,
mergers,
or
takeovers. Since
governments often restrict ownership and merger between companies
in different countries, most consolidation takes place within a
country. In the U.S., over 200 airlines have merged, been taken
over, or gone out of business since deregulation in 1978. Many
international airline managers are lobbying their governments to
permit greater consolidation to achieve higher economy and
efficiency.
