46:(CAB) during the period of airline regulation 1938โ1978 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.
153:
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 with 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
305:, 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,

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.
456:
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

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

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

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

were largely that โ 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
493:
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

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

and thus was subject to less regulation. For that reason, Southwest has never been counted as a legacy carrier. As related below, the term "intrastate airline" meant more than simply operating within a single state. Prior to 1981, Hawaiian

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
376:
1979โ1991 was a highly turbulent time for legacy airlines โ during this time 13 of the original 23 passenger jet legacy carriers vanished through merger and collapse as they struggled to adapt to the new environment. During this period, many legacy airline features developed as an adaptation to

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
