Yes, as of 2026, all seven terminals at Philadelphia International Airport (PHL)—Terminals A-West, A-East, B, C, D, E, and F—are connected airside (behind the security checkpoints). This means that once you have cleared security at any terminal, you can walk to any other gate without having to exit the secure area or be re-screened. The terminals are arranged in a linear fashion, and a full walk from A-West to F takes approximately 30 to 35 minutes. For those who prefer not to walk, the airport operates a free shuttle bus within the secure area, with stops at Terminal F (Gate F-14), Terminal C (Gate C-16), and Terminal A-East. This "connected" layout makes PHL an excellent airport for layovers, allowing passengers to access any of the 150+ restaurants and shops across the entire airport complex regardless of which airline they are flying.
