Domestic-to-Domestic: 45 min. Domestic-to-International: 60 min. International-to-Domestic: 90 min. International-to-International: 90 min. These are the shortest layovers airlines will sell at Philadelphia International.

PHL is a major American Airlines hub with a linear terminal layout that makes most domestic-to-domestic connections a straightforward walk, but international arrivals funnel through a separate customs process that can eat significant time. The airport's single-file terminal design (A through F) means long walks are common even without a terminal change, and Terminal F requires a shuttle bus that adds uncertainty to tight connections. Terminals A-East through E are connected by a continuous post-security corridor with moving walkways, making walking the primary transit mode and generally taking 15-25 minutes end to end. Terminal F, used mainly for American Eagle regional flights, sits apart and requires a dedicated shuttle bus that can take 10-15 minutes including wait time. International arrivals at Terminal A-West must clear Customs and Border Protection before re-entering the secure area, requiring a full security re-screening for onward connections.
