Philadelphia International Airport

Philadelphia International is American Airlines' primary trans-atlantic gateway on the U.S. East Coast, a role that outsizes the airport's otherwise mid-tier overall passenger volume. It serves 50 airlines on 470 routes to 202 nonstop destinations, and despite a metropolitan market smaller than New York, Boston, or Washington, PHL operates more daily nonstop flights to Europe than BOS or IAD. The airport sits 11 km (7 mi) southwest of Center City Philadelphia on 2,598 acres (1,051 ha) straddling the Delaware River estuary. The hub dynamic here is distinctive: American inherited the Philadelphia operation from its 2013 merger with US Airways, which had built PHL as its trans-atlantic hub to exploit the airport's geographic position halfway between New York and Washington — close enough to draw traffic from both markets while avoiding the slot constraints of JFK and EWR. The network reaches most major European capitals, secondary European cities (Athens, Dublin, Edinburgh, Zurich, Rome), and a dense Caribbean and Mexican program. Four runways including the 12,000 ft (3,658 m) 09R/27L support morning and evening long-haul banks. Seven terminals (A-West and A-East, B, C, D, E, F) are arranged in a linear configuration connected airside; Terminal A-West is the dedicated international pier with a U.S. customs and immigration processing facility sized for the trans-atlantic fleet. Terminal F serves the American Eagle regional operation, the largest regional-jet feed program in the U.S. East Coast. The airport's long-term Capacity Enhancement Program includes a proposed fifth runway parallel to 09/27 to increase peak arrival capacity under instrument conditions.
