Does Delta use Terminal 1 at JFK?

News & Advisories. You will now find Delta's operations, including check-in, security, all gates and baggage claim solely in Terminal 4 (T4).



No, in 2026, Delta Air Lines does not use Terminal 1 at John F. Kennedy International Airport (JFK). Delta is centrally located in Terminal 4, which serves as its primary international hub and "flagship" terminal in New York. Terminal 4 has undergone massive expansion to accommodate Delta's growth, including the addition of several new gates and a high-end Delta One Lounge for premium passengers. Terminal 1 is primarily used by a consortium of international carriers such as Air France, Lufthansa, and Korean Air. It is important for travelers to note that JFK is currently undergoing a multi-billion dollar transformation; while a new Terminal 6 is opening its first gates in 2026, Delta's operations remain firmly anchored in Terminal 4. If you accidentally arrive at Terminal 1 for a Delta flight, you will need to take the AirTrain, which runs in a loop between all terminals, adding at least 15–20 minutes to your transit time within the airport.
