Travelers flying through New York’s John F. Kennedy International Airport will now be able to check security line wait times before even arriving at the airport.

A newly launched feature on the official JFK Airport website allows passengers to track live TSA security wait times across different terminals. The data is updated frequently, giving travelers a real-time look at how long the lines are before heading to the airport.

Airport officials say the goal is to reduce uncertainty and help travelers better plan their arrival times. Security lines at JFK can vary widely depending on the time of day and travel season, with average waits typically ranging from about 15 to 30 minutes but sometimes stretching much longer during peak travel periods.

The tool is expected to make travel through one of America’s busiest airports more predictable, allowing passengers to time their arrival more accurately and avoid unnecessary waiting in long security lines, and comes as very welcome news to the thousands of us that travel through JFK so often.
