As of early 2026, Swiss International Air Lines (SWISS) operates out of Terminal 4 at John F. Kennedy International Airport (JFK). However, travelers should be aware of the ongoing massive JFK redevelopment project. SWISS is a founding member of the Star Alliance and is slated to eventually move into the new Terminal 6, which is currently undergoing phased openings throughout 2026. This move will co-locate SWISS with its partner Lufthansa and other Star Alliance carriers to streamline connections. Terminal 4 is one of the most modern and largest terminals at JFK, featuring high-end retail and the premium Swiss Lounge (often shared with Lufthansa or accessed through the Virgin Atlantic Clubhouse depending on specific time slots). Since terminal assignments can shift during major construction projects, always double-check your digital boarding pass or the official JFK airport website on the day of travel to ensure you head to the correct check-in area and avoid unnecessary transit between terminals via the AirTrain.
