Philadelphia International (PHL) is 8 miles southwest of Center City — one of the most transit-friendly airports in the US thanks to SEPTA's Airport Regional Rail Line, which drops you in Center City in 25 minutes for $6.75. Alternative airports: Newark (EWR, 90 min), New York JFK/LGA (2 hr+), Atlantic City (ACY, 90 min).
Philadelphia's primary airport — 7 terminals (A-East, A-West, B, C, D, E, F), all connected post-security via shuttle bus and walking. Major hub for American Airlines (PHL is American's 4th-largest hub), plus full service from Delta, United, Southwest, JetBlue, Frontier, Spirit, Alaska. Direct international flights to most of Europe (Heathrow, Frankfurt, Paris, Madrid, Rome, Amsterdam, Munich, Zurich, Lisbon, Reykjavik), Mexico, Caribbean. SEPTA's Airport Regional Rail Line stops at every terminal (above-ground stations connected by walkways) — Philadelphia is the only major US city with that level of in-airport rail access.

NJ Transit + Amtrak both run between EWR and Philadelphia 30th Street Station (~1 hr 15 min, $25-50). Useful if PHL fares are high during World Cup peak. Avoid LaGuardia or JFK (NYC) — 2.5+ hours each way.
PHL has 7 terminals (A-East, A-West, B, C, D, E, F) connected post-security via shuttle bus and walkways. American Airlines dominates Terminals A, B, C, D; the rest of the carriers split E and F. International arrivals process at Terminal A-West.
PHL has been undergoing $1B+ in renovations through the late 2020s — Terminal A-West got a major upgrade in 2024, Terminal B baggage hall is being modernized in 2025-26.
