Delta flights operate out of Terminal 4 at John F. Kennedy International Airport (JFK) . Terminal 4 is the main hub for Delta Airlines and the largest terminal at JFK, serving 30 international and domestic airlines. Delta One and Sky Priority customers should follow the roadway signs to Zone B for drop-off. If you are connecting to a partner airline such as Air France, China Eastern, or Korean Air, you will need to change terminals and follow airport signage to the AirTrain and inter-terminal bus. However, if you are on Delta metal, you will be out of Terminal 4.
