Delta Airlines Jfk Terminal operates out of multiple terminals at JFK International Airport in New York City, depending on the flight destination and origin.

Delta's main terminal at JFK is Terminal 4, which is the hub for the airline's domestic and international flights. Terminal 4 is located on the south side of the airport and is connected to the other terminals via the JFK Airport AirTrain.

Delta also operates out of Terminal 2 and Terminal 3, which are located adjacent to each other on the north side of the airport. These terminals are used for Delta's domestic flights and are connected to each other via a walkway.

I would recommend checking your flight itinerary or contacting Delta Airlines directly to confirm which terminal your flight is departing from or arriving at, as it can vary based on factors such as the time of day and the specific route.
