Strengthening Delta’s Presence at JFK

John F. Kennedy International Airport
Delta Air Lines Terminal 4 Expansion, Phase 2

Jamaica, New York, USA

This expansion project improves the passenger experience and brings long-term flexibility to Terminal 4.

To consolidate its operations and improve the passenger experience, Delta Air Lines initiated a redevelopment of its facilities at JFK International Airport.

For an expansion project that added 75,000 square feet and 11 gates to Terminal 4’s Concourse B, Delta selected HOK to provide structural engineering, overall terminal engineering integration and planning for flexibility. The expansion includes space for international arrivals and for long-term adaptability and growth. It has allowed for 80 percent of the “Delta Connection” flights to relocate from Terminal 2 to Terminal 4. JFK International Airport is now Delta’s second-largest hub.

The expansion accommodates 11 regional jet gates or six gates used for Group IV aircraft. It also accommodates two Group IV gates that swing from domestic to international to connect to the existing sterile corridor. The gates feature enclosed jet bridges and are near the renovated Sky Club and restaurants. The project also created a concessions node.

The flexible new space has the capacity for another floor and bay to be added in the future and, if needed, to accommodate Group V aircraft.

The project involved extensive integration with the existing Concourse B structure, including tying into the existing lateral system and careful consideration for construction phasing in order to avoid interruption of the fully operational facility.

Working with Delta as part of an integrated team that included Gensler as lead architect, HOK provided structural engineering services through all phases of design and on-site construction administration.
