Service as American Eagle was flown between 2012 and 2019 and service under the United Express brand began in 2009.

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.
Essair was incorporated in 1939, the first airline authorized by the federal Civil Aeronautics Board (CAB) to fly as a local service carrier in the United States.
