Yes, you can stay overnight at JFK, but your experience will vary significantly depending on which terminal you are in. Terminal 4 is the only one at JFK that operates 24/7, offering various 24-hour food and drink options and plenty of seating, though it does not have dedicated sleeping pods. For a far more comfortable 2026 experience, the TWA Hotel is located right at the airport (Terminal 5) and offers both overnight and "day stay" rooms with a 1960s aesthetic. If you are staying in the public areas, be prepared for bright lights and frequent security announcements; it is a "best practice" to bring an eye mask and earplugs. If you have a long layover and want a proper bed but don't want to pay TWA prices, several nearby hotels like the Residence Inn JFK offer 24-hour free shuttles, making them a more restful 2026 alternative than sleeping on terminal benches.
