At New York's JFK Airport in 2026, immigration and customs facilities are located in Terminals 1, 4, 5, 7, and 8. Terminal 4 is the largest international hub, serving major carriers like Delta, Emirates, and Virgin Atlantic. Terminal 1 (which includes the newly opened sections of the New Terminal One) handles a massive volume of international arrivals from Air France, Lufthansa, and Japan Airlines. Terminal 8 is the primary home for American Airlines and British Airways. Terminal 5, while primarily domestic for JetBlue, has its own customs facility for international arrivals from the Caribbean and Europe. Terminal 7 remains an active international gateway for several smaller carriers and Aer Lingus. Note that Terminal 6 is currently under heavy construction and is not handling arrivals. If you are arriving on a domestic flight with an international connection, you generally do not pass through immigration unless you are re-entering the country from abroad.
