Source: FlyerIntel analysis of US DOT BTS data · July 2023 – July 2026 · “Usually departs” is the scheduled time each flight number most often had over the period; airlines retime flights, so confirm the time on your booking.

2h 0m before your 7:00 PM departure
How this was worked out
- FlyerIntel cannot currently obtain live security wait times for JFK, so this figure does not account for the queue on the day.
- It does not include your journey to the airport, parking, or a shuttle from a remote lot.
- International departures, and travel with children, checked pets or special assistance, need more time.
