A four-hour layover at JFK is too short to leave for Manhattan given New York traffic, but it is enough time to explore the airport's unique features. The most iconic destination is the TWA Hotel in Terminal 5, where you can visit the "Connie" airplane-turned-cocktail-lounge or the museum exhibits celebrating 1960s jet-age glamour. If you prefer relaxation, Terminal 4 offers the widest range of high-end lounges (some accessible via day passes) and premium dining options like Shake Shack or Blue Smoke on the Road. For those needing a refresh, XpresSpa locations are available in Terminals 1, 4, and 5 for quick massages or facials. If you are a shopper, Terminal 4 has a vast Duty-Free section and luxury brands like MAC and Jo Malone. For a quiet moment, there is an interfaith chapel landside in Terminal 4. In 2026, Terminal 6 is also becoming a major hub of activity as the airport's multi-billion dollar renovation continues, but always allow at least 30 minutes to transit between terminals via the AirTrain if your gates are far apart.
