Around 59 million people are transported through John F. Kennedy International Airport each year, making it one of the busiest airports in the world relative to its size. Six terminals are located outside of a rectangular loop at JFK. 1, 2, 4, 5, 7, and 8 make up this group. Air Train connects every terminal. Parking, guest access, car entry, and pre-security are all available inside the circle. Areas on the outside belong to the airside, with access restricted to authorised workers and travellers with tickets for flights.
The JFK Terminal-2, often known as the JFK Delta International Terminal, is used only by Delta airlines. It has 11 gates for boarding (which are jet-equipped C60-C70). Following the demise of Northeast Airlines and Braniff, Delta Air Lines took over this terminal from Pan Am. Until 2013, Terminal 2, in conjunction with Terminal 3, provided service to the majority of Delta's operations. JFK's terminal 2 served as the main hub for passengers for Delta Air Lines' traffic flow. As Terminal 4 developed between 2013 and 2015, Delta centralised the majority of its flight operations, including both international and domestic flights, at this new terminal. As T4 was finished, the boarding gates at Terminal 2 were preceded by the letter "C".
