PMDG 737-600 USAir (N356AU) Classic Chrome (Weathered)

US Airways (formerly USAir) was a major U.S. airline that operated from 1937 until its merger with American Airlines in 2015. It was originally founded in Pittsburgh as a mail delivery airline called All American Aviation, which soon became a commercial passenger airline. In 1953, it was renamed Allegheny Airlines and operated under that name for a quarter-century. In October 1979, after the passage of the Airline Deregulation Act, Allegheny Airlines changed its name to USAir. A decade later it had acquired Piedmont Airlines and Pacific Southwest Airlines (PSA), and was one of the U.S.'s seven transcontinental legacy carriers. In 1997, it rebranded as US Airways.
