 Delta Air Lines, the Port Authority of New York and New Jersey, and JFK International Air Terminal will continue expansion at John F. Kennedy International Airport with a $175 million project that will add 11 gates and 75,000 square feet to Terminal 4's Concourse B. Delta has committed an additional $5 million for information technology enhancements. With the new expansion, Terminal 4's Concourse B will house 27 Delta gates and completely replace Delta's current Terminal 2 regional jet operation. Each of the new gates will feature a dedicated boarding counter, seating area and jet bridge, eliminating the need for ramp-level boarding, which currently exists at Terminal 2. The new project is in addition to a massive $1.2 billion redevelopment at Terminal 4 that will debut in May. That expansion, which is 90 percent complete, features nine new and seven renovated international gates; improved and renovated check-in areas, including a dedicated Sky Priority check-in area; a centralized security checkpoint; new dining and retail offerings; a new 24,000-square-foot flagship Delta Sky Club with a Sky Deck outdoor terrace; dual taxiways for less congestion and shorter taxi times; and improved Customs and Border Protection and baggage claim facilities. The expanded Terminal 4 will replace the outdated Terminal 3 facilities; demolition of Terminal 3 is expected to be completed by summer 2015, at which time the site will be used for aircraft parking.
