Defining a Legacy in the Skies
In the United States, a 'legacy carrier' refers to an airline that was once regulated by the powerful Civil Aeronautics Board, or CAB, between 1938 and 1978. Imagine a time when the government dictated almost every aspect of commercial air travel—from routes to ticket prices. The CAB wielded immense control over these early giants of the sky.
Yet, here's a curious twist: many of the features we associate with today's legacy airlines—things like frequent flyer programs and complex fare structures—actually emerged after deregulation. These innovations were born from a desperate need to adapt to an unfamiliar, hyper-competitive environment.
The Surviving Giants
Today, after decades of mergers, acquisitions, and even bankruptcies, only a few of these original titans remain. As of late 2024, following the completion of the Alaska Airlines and Hawaiian Airlines merger, we count four primary surviving legacy carriers.
These names represent a direct lineage to the pioneering airlines that navigated the tightly controlled skies of mid-20th century America.

Who Isn't a Legacy Carrier?
So, if regulation is the key, what kind of airline isn't considered a legacy carrier? Broadly speaking, any airline founded after the regulated era—after 1978—falls outside this definition. Think of modern low-cost giants like JetBlue or Spirit Airlines; they entered a completely different playing field.
Another crucial exception are airlines that, despite existing before 1979, were never regulated by the CAB. The most famous example is Southwest Airlines. From its inception in 1971, Southwest operated solely within Texas, classifying it as an 'intrastate airline' and thus exempt from federal oversight.
This intrastate status allowed Southwest to innovate with lower fares and simpler operations, effectively being 'deregulated' long before the rest of the industry. This gave them a significant competitive advantage as the industry later opened up.
Interestingly, not all intrastate carriers escaped CAB regulation. Hawaiian Airlines, for instance, operated only within Hawaii before 1981 but was still regulated. Why? Courts determined that due to federal control over waters just three miles offshore, flights between islands were deemed interstate commerce.
Beyond American Borders
While the term 'legacy carrier' is predominantly American, the concept has global relevance. Many nations once had similar tight regulations over their own airlines. When deregulation swept across the world, national flag carriers like British Airways, Air France, or Lufthansa found themselves in a similar struggle against new, often lower-cost competitors like Ryanair or EasyJet.
The Legacy of Regulation: A Double-Edged Sword
Before 1979, the CAB essentially ran its regulated airlines like a cartel. It carefully limited competition and set uniform, often inflated, fare levels across the nation. This meant that legacy carriers, while protected, developed a costly business model—a significant challenge when deregulation hit.
The history of these carriers post-deregulation is largely a saga of battling these high costs. It's a testament to the brutal nature of the market that, with the notable exception of Alaska Airlines, every single surviving US legacy carrier has gone through bankruptcy since 1978. It was a fight for survival.
A Snapshot of the Regulated Era
In 1978, on the eve of deregulation, the American skies were dominated by 23 CAB-regulated jet carriers. These included the major 'trunk carriers' connecting large cities, 'local service carriers' serving smaller communities, and the island-hopping airlines of Hawaii and Alaska.
Adapting to a New World: 1979-1991
The first decade or so after deregulation was incredibly turbulent. A shocking 13 of those original 23 jet carriers either collapsed or were absorbed into others. To survive, the remaining legacy airlines had to rapidly invent new strategies, completely overhauling their operations.
Mergers became a popular, though controversial, strategy to reduce competition and gain market share. Airlines like Western Airlines merged into Delta, and several local service carriers consolidated into larger entities. Many of these mergers faced scrutiny but were ultimately approved, reshaping the airline map.
Cost-cutting was paramount. Carriers explored controversial methods, like using bankruptcy law to renegotiate labor agreements—a tactic Continental Airlines famously employed in 1983. American Airlines pioneered two-tier wage scales, where new hires earned less than long-term employees, fundamentally altering labor costs.
Customer loyalty and revenue generation also transformed. Frequent flyer programs, like American Airlines' AAdvantage introduced in 1981, created powerful incentives for repeat business. This era also saw the birth of complex fare structures, allowing airlines to maximize revenue by segmenting travelers through mechanisms like advanced purchase requirements and Saturday-night stays.
The 'hub-and-spoke' system, where flights route through central airports, became the industry standard. While the concept existed earlier, CAB restrictions largely prevented its widespread adoption. Post-deregulation, airlines rapidly developed these efficient networks. They also aggressively expanded internationally, seeking less competitive routes crucial for business travelers.
Finally, legacy carriers began to align deeply with commuter airlines, later known as regional airlines. Through code-sharing agreements, these smaller carriers began to feed passengers into the larger legacy networks, often adopting their branding and livery. This created the integrated regional feeder systems we see today.
Despite these monumental efforts, not all could adapt. Giants like Eastern Air Lines and Pan Am, once symbols of American aviation, famously collapsed in 1991. By that year, 13 of the 23 original CAB legacy jet passenger airlines had either ceased operations or been absorbed, leaving only 10 by the early 1990s.
The Final Consolidation: From Ten to Four
The path to today's four major legacy carriers continued with a series of significant mergers and acquisitions in the 21st century. Bankrupt TWA was absorbed by American in 2001, and America West acquired US Airways in 2005, taking on the larger carrier's name.
The late 2000s and early 2010s saw further consolidation: Aloha Airlines ceased operations in 2008; Northwest merged with Delta in 2008; Continental joined United in 2010; and a newly revitalized American Airlines was acquired by US Airways in 2013, solidifying the major players. The most recent major move, Hawaiian's merger with Alaska Airlines in 2024, further streamlines the landscape.

Legacy carrier
In the United States, a legacy carrier is an airline that was once economically regulated by the Civil Aeronautics Board (CAB) during the period of airline regulation 1938–1978 or can trace its origin to one that did. The CAB was a now defunct federal agency that tightly controlled almost all US commercial air transport during that period. As related below, many features associated with the legacy airline business model were actually developed not during the regulated era, but instead in the first decade or so of the deregulated era, as legacy carriers adapted to an unfamiliar competitive environment.
While the term "legacy carrier" is most often used in a US context, it is possible to speak of legacy carriers elsewhere, since tight airline regulation was once the global norm and following US airline deregulation, many other countries went through some kind of airline deregulation. Non-US carriers with origins that precede liberalization can be viewed as legacy carriers. For instance, in Europe, flag carriers such as British Airways, Air France, KLM, Iberia, and Lufthansa, (with origins well before the liberalized era) can be viewed as legacy carriers in contrast to airlines such as Ryanair, EasyJet, Wizz Air, and so forth.
Surviving legacy carriers
Legacy carrier
There are currently four surviving legacy carriers, with Alaska Airlines and Hawaiian Airlines having completing their merger on September 18, 2024:
• Alaska Airlines/Hawaiian Airlines • American Airlines • Delta Air Lines • United Airlines
Each of the above was founded by 1932 (94 years ago), although typically under a different name than they are currently known as.
• Any airline founded after the regulated era. A few prominent examples of such carriers include America West Airlines, ValuJet, Virgin America, JetBlue, and Spirit Airlines. • Any US airline with a pre-1979 origin that was not regulated by the CAB. There are two such significant US airlines still in operation. The most prominent is Southwest Airlines, which started operations in 1971 but was never subject to CAB regulation because it was an intrastate airline and thus was subject to less regulation. For that reason, Southwest has never been counted as a legacy carrier. SkyWest Airlines, founded in 1972, was a commuter carrier during the CAB era, thus was not subject to CAB regulation. As related below, the term "intrastate airline" meant more than simply operating within a single state. For example, Hawaiian Airlines operated only within the state of Hawaii prior to 1981, yet was CAB-regulated.
Significance
Legacy carrier
Prior to 1979, the CAB regulated its carriers as a cartel, strictly limiting competition between them and setting uniform fare levels nationally. Such fare levels were above those that would prevail in a free market, as proven by comparison with fares charged by less-regulated intrastate carriers during the regulated era. CAB carriers thus entered deregulation with a legacy of high costs. The history of the legacy carriers following deregulation is in significant part the story of their struggle with this legacy, their efforts to cut costs and to compensate for such costs through various business model adaptations. One indication of this long-term struggle is that of the surviving US legacy carriers, all have gone through bankruptcy since 1978 with the exception of Alaska Airlines.
Context
Legacy carrier
A complete list of CAB-regulated scheduled airlines in 1978, the last year of the regulated era, is available in the Civil Aeronautics Board article. Those are the legacy carriers as of the start of the deregulated era. For completeness, there is also a list of charter carriers (the CAB called them supplemental air carriers) and all-cargo carriers (such as Flying Tiger Lines) from the same year. Whether CAB-era supplemental or all-cargo airlines count as legacy carriers is largely moot since none survive and they had little impact on the passenger industry after deregulation.
Of the 1978 scheduled passenger CAB carriers, as shown in the table referenced above, 23 flew jets:
• Ten domestic trunk carriers (American, Braniff, Continental, Delta, Eastern, National, Northwest, TWA, United, Western) plus Pan Am • Eight local service carriers (Allegheny, Frontier, Hughes Airwest, North Central, Ozark, Piedmont, Southern, Texas International) • The two Hawaiian carriers: Hawaiian and Aloha • Two of the Alaskan carriers: Alaska and Wien Air Alaska
Airlines not regulated by the CAB
During the 1938–1978 regulated era, intrastate airlines were those that minimized participation in interstate commerce, most obviously by operating only within a single state, but also by measures such as not selling joint tickets with other carriers for itineraries that crossed state lines, not selling tickets in other states and so forth. By doing so, they sidestepped regulation by the CAB and were able to be economically regulated instead by an agency of their state, most of which were more flexible than the CAB. However, despite not flying outside of Hawaii, Hawaiian Airlines and Aloha Airlines were CAB-regulated carriers during this era, and participated in the interstate airline system by, for instance, selling connecting tickets to elsewhere in the US. For many reasons, neither airline was an intrastate carrier. For instance, it was determined in the courts that an intrastate carrier was essentially legally impossible in Hawaii. Federally-controlled waters start three miles offshore, which made most flights between islands subject to federal regulation.
Southwest started operations in 1971 and from 1971 thru 1978 was a Texas intrastate carrier, escaping CAB regulation. It was, in a sense, a carrier that was deregulated even before deregulation. Other important intrastate carriers included Pacific Southwest Airlines, Air California (later AirCal) and Air Florida, none of which survived the 1980s.
While the CAB was legally unable to regulate intrastate carriers, from 1952, it chose not to regulate airlines flying "small" aircraft, leading to the growth of a deregulated air taxi or commuter airline segment decades before wider deregulation. Any US airline that was a commuter carrier before 1979 therefore also escaped CAB regulation.
A prominent example of a CAB-era commuter carrier survives today: the large regional airline SkyWest, which first started operating in 1972 as a commuter carrier.
One CAB-era commuter airline made a post-deregulation impact at a mainline level and merged into a legacy carrier: Empire Airlines started in the mid-1970s as a commuter airline in Upstate New York, was certificated in 1979 and transitioned to jets shortly thereafter. It merged into Piedmont in 1986.
Legacy carrier post-deregulation adaptation
1979–1991 was a highly turbulent time for legacy airlines – during this time 13 of the original 23 passenger jet legacy carriers exited through merger and collapse as they struggled in the new environment. During this period, many legacy airline features developed as an adaptation to deregulation. Legacy carrier strategies included:
• Mergers: By the end of the 1980s, two of the 10 former trunk carriers had merged out of existence (National into Pan Am and Western into Delta) as had seven of the eight former local service carriers: Frontier and Texas International into Continental; Hughes, North Central and Southern into Republic which merged into Northwest; Ozark merged into TWA; and Piedmont into USAir. Some of these mergers were motivated by desires to reduce competition and were judged anticompetitive by the US government before nonetheless being approved by the US Department of Transportation. • Expansion: All other things being equal, airline expansion drives down average costs by reducing average employee seniority (as new employees are hired), so average employee pay drops. An example of successful post-deregulation expansion was Piedmont, which expanded up and down the East Coast and was profitable every year after deregulation until it merged into USAir. The rapid expansion of Braniff, on the other hand, led to its collapse in 1982, the first legacy jet carrier to cease operation (the first former CAB carrier overall to cease operation was turboprop airline Air New England in 1981). • Use of bankruptcy law to abrogate labor agreements and impose lower market wages as pursued by Continental Airlines in its 1983 bankruptcy. • Lower pay scales for new hires (retaining higher pay scales for legacy employees), as pioneered by American Airlines in 1983. • Loyalty programs: Frequent-flyer programs as we know them did not exist prior to the introduction of the American Advantage frequent-flyer club by American Airlines in 1981. This allowed legacy carriers to leverage their greater size. • Development of complex fare structures overseen by revenue management programs, including reliance on price discrimination (selling the same seat for much more to a price-insensitive business traveler, and much less to price-sensitive personal travelers through mechanisms such as an advanced nonrefundable purchase, a required round-trip purchase with a Saturday-night stay to obtain the lowest prices) - again, led by American in 1985. • Hub-and-spoke systems: Delta had a well-developed Atlanta hub prior to 1979, and the advantages of hubs were understood by many, but most airlines did not have the opportunity to develop hub-and-spoke systems prior to deregulation in 1979 because they could only fly where the CAB let them. Thus hubs were, for the most part, a post-deregulation development. • International expansion: Pre-deregulation the domestic trunk airlines were largely that – mostly domestically focused. Legacy carriers made a concerted effort to expand internationally, since such flights were important to business travelers and less subject to low-cost competition. United bought Pan Am's Pacific routes, American bought Eastern's Latin American routes (previously those of Braniff before it collapsed), Delta bought Pan Am's European routes and so forth. • Alignment of commuter airlines (later called regional airlines) with legacy carriers. Allegheny pioneered this in the 1960s in the CAB era, developing the Allegheny Commuter system of commuter carriers under common branding and liveries. For Allegheny it was in part a way to cease operating smaller routes itself. In the mid-1980s, the government permitted legacy carriers to code-share with commuters. This resulted in the quick alignment of commuters with legacy carriers as it became difficult for independent commuter carriers to survive, with commuters taking on the identity of the legacies with whom they were aligned. Some carriers, like American and Continental, bought some of the commuters with which they aligned.
Eastern and Pan Am proved unable to adapt, each collapsing in 1991. Including the earlier shutdowns of Braniff in 1982 (see above) and Wien Air Alaska in 1984, by 1991, four former CAB jet passenger airlines ceased operating. Added to the nine legacy jet carriers that merged and 13 of the 23 CAB legacy jet passenger airlines exited by 1991, leaving only 10 left, of which three were small (Alaska, Aloha and Hawaiian):
From ten in 1991 to four today
• In 2001, bankrupt TWA merged into American Airlines. • In 2005, bankrupt US Airways was bought by America West Airlines, which adopted the name of the larger carrier. The resulting carrier was considered a legacy airline, given its heritage was a majority legacy carrier. • In 2008, Aloha Airlines collapsed. • In 2008, Northwest Airlines agreed to merge with Delta Air Lines. • In 2010, Continental Airlines agreed to merge with United Airlines. • In 2013, US Airways and bankrupt American Airlines agreed to a 'stock swap' merger, with AMR shareholders getting a majority of the combined shares. The combined airline adopted the American Airlines name and headquarters. • In 2023, Hawaiian Airlines agreed to merge with Alaska Airlines, and their parent company, Alaska Air Group, retained both brands after the completion of the merger.
