Layover calculator — John F. Kennedy International Airport (JFK)

Enter your connection details below. The estimate uses known terminal connections, security re-check rules, and facility locations — each backed by sources and a last-verified date. Where data is missing the result says so instead of guessing.

The interactive calculator needs JavaScript. Terminal connection times and facility data are still visible on the main JFK page.
