JFK almost always has some level of delay because it’s one of the busiest international hubs in the U.S. On many days, the FAA lists JFK as operating normally but with minor airborne or taxi delays of around 15 minutes, which is considered routine.
Because JFK’s status can change quickly due to storms, construction or ATC programs, the most accurate way to know today’s situation is to check a live tracker before you leave home, then confirm with your airline’s travel service. If you’re already at the airport, airport services at the information desk or your departure gate can give you the latest on departure times, rebooking, and connections.
