Terminal 4 is one of the largest, most spacious terminals in the New York area. More than 32 international and domestic airlines carry millions of passengers annually. Regarded as `The Terminal of Choice', in January 2015 the facility completed a second phase of major expansion project for Delta Air Lines which added additional capacity and state-of-the-art technology. JFKIAT, LLC, the operator of Terminal 4, offers airlines a dedicated management company that oversees all landside, airside and terminal operations. Travelers benefit from a commitment to passenger service. Terminal 4 at JFK International Airport is a successful paradigm for air terminal management and a model of public-private partnership.
