In 2026, Delta Air Lines operates exclusively out of Terminal 4 at John F. Kennedy International Airport (JFK). Following a multi-year consolidation and expansion project completed in 2023, Delta moved all of its operations out of the now-demolished Terminal 2 and centered its hub in Terminal 4. This massive terminal now serves as Delta's primary gateway for both domestic and international flights, featuring upgraded check-in areas, expanded baggage systems, and two massive Delta Sky Club lounges, one of which includes a popular "Sky Deck" with views of the runways. Delta's presence is primarily concentrated in Concourse B and the newly expanded Concourse A, with over 38 gates dedicated to its aircraft. This consolidation has greatly improved the passenger experience by eliminating the need for shuttle buses between terminals for connecting flights. While Delta codeshare partners may occasionally use other terminals, Terminal 4 is the definitive home for all Delta-branded operations at JFK.
