Philadelphia Municipal became Philadelphia International in 1945, when American Overseas Airlines began flights to Europe. The airport saw massive growth and many airlines over the years. Including multiple hubs. Now a hub for American Airlines, 70% of its traffic is from its hub carrier.

The airport was built in 1942 as Naval Air Station Atlantic City and has served the Atlantic City area ever since. In August 1943, NAS Atlantic City changed its mission to strictly fighter training, consisting of low and high altitude gunnery tactics, field carrier landing practice (FCLP), carrier qualifications (CQ), bombing, formation tactics, fighter direction, night operations and an associated ground school curriculum. Since 1958, the airport has been home to Atlantic City Air National Guard Base and the 177th Fighter Wing (177 FW), an Air Combat Command (ACC)-gained unit of the New Jersey Air National Guard, operating the F-16C/D Fighting Falcon.
