U.S. Airline Mergers and Acquisitions

The table below is an unofficial compilation of completed (not merely proposed) mergers and acquisitions since the inception of the U.S. airline industry. Neither the U.S. Department of Transportation nor A4A maintains official records of airline M&A activity. As such, we cannot verify the accuracy of each individual entry. The table is provided as a service rather than an authoritative source. It is the only known comprehensive, centralized, publicly available source.
