Is it allowed, and what the rule actually says
Yes, and the airport's framing is warmer than most. Asked whether it has sleeping facilities, it answers that there are none, and then says it is "open and staffed 24 hours a day" and does "all we can to make your extended or overnight stays as welcoming and comfortable as possible". That is an airport treating an overnight as something to accommodate rather than to move along.
There is a limit, and Terminal 4 is the one that publishes it. Its rules and regulations say no person may "sleep or lie on any area of Terminal 4 where such activity may be hazardous, interfere with the operation of Terminal 4, pedestrian flow or comfort of Terminal 4 users." A separate clause on loitering says nobody may remain at the terminal who "is found sleeping therein, and is unable to give a satisfactory explanation of his/her presence."
Read those together and the practical rule is clear. A boarding pass is the satisfactory explanation. A passenger with a flight in the morning sleeping in a seat is fine; the rule exists for people with no travel reason to be there, and for anyone blocking a walkway or sprawled somewhere unsafe. Sleep in a seating area rather than a corridor, keep your bag against you, and nobody has any reason to wake you.
The same rules ban bathing, showering, laundering and changing clothes anywhere that is not a designated facility, which is worth knowing before you plan a restroom wash at 4:00 AM.
The sleep pods question, answered properly
Ask the airport whether JFK has sleep pods and it says no: "There are no sleeping pods or similar facilities." Ask its own venue directory the same question and you get a different answer, and the gap is worth closing because "no pods at JFK" sends people to the floor when they could have had a bed.
What the directory actually lists:
- Minute Suites, Terminal 4, past security near Gate B39, listed as open 24 hours. A private room with a daybed, rented by the hour.
- Minute Suites, Terminal 8, landside near Gate 37, listed 12:00 AM to 11:45 PM. The description names a daybed sofa, a workstation, high-speed Wi-Fi and entertainment.
- Jabbrrbox Escape Pods, Terminal 8, landside at check-in on Level 3, open 24 hours. These are work pods rather than beds: quiet, private and equipped, but designed for sitting up.
So the honest form of the airport's answer is there is nothing free, rather than there is nothing. None of the three publishes a rate, so ask at the door or book ahead, and note the split: the room you can actually lie down in past security is at Terminal 4 only. At Terminal 8, Minute Suites is on the check-in side, so using it means leaving the secure area and screening again in the morning.
Which terminal to be in
If you have any say in it, this decides the night. The differences between terminals after midnight are much larger than the differences during the day.
Terminal 4 is the one to be in. It is the only terminal with food open past security around the clock, and there are six such venues: Boulton & Watt at Gates A3 and A5, a McDonald's in the Retail Hall, a Starbucks and The Brooklyn Counter at Gate A2, Melt Shop, and a Dunkin' on the landside arrivals level. Its baggage storage desk is open 24 hours, Minute Suites operates there through the night, and the Capital One Lounge is the one lounge at JFK that never closes.
Terminal 8 is second. Its four American and British Airways lounges open at 4:15 AM, the earliest doors at the airport, and the Greenwich Lounge runs to 1:15 AM, which leaves a gap of only three hours. Minute Suites and Jabbrrbox are here, both landside. Its 24-hour food is one Dunkin' at baggage claim.
Terminal 1 and Terminal 7 are the ones to avoid. Neither has anything open through the small hours. Terminal 1's airside units run to midnight and nothing there serves again before 5:00 AM. Terminal 7's food court closes at midnight and its one late option, a wine bar, shuts at 1:00 AM, with nothing again until 4:00 AM. Terminal 5 sits in between: one 24-hour Dunkin' landside, and its first airside coffee at 3:00 AM, which is the earliest at the airport.
If you are on a connection that changes terminals anyway, the AirTrain is free between them, so moving to Terminal 4 for the night costs nothing but the ride and a second pass through security in the morning. The terminal overview covers which airlines are where.
The landside option, and it is unusual
JFK has one hotel on the airport itself, and it is a 1962 landmark you can walk to. The TWA Hotel occupies Eero Saarinen's TWA Flight Center beside Terminal 5, and the two original flight tubes now connect the headhouse to its guest wings, so there is no shuttle, no taxi and no waiting on a curb at 1:00 AM.
That matters more on a short overnight than a star rating does. A room for six hours you can reach on foot from Terminal 5 beats a cheaper room that costs you a shuttle in each direction. The hotel also sells a daytime stay for people who want a room for part of a day rather than a night.
You do not need a room to use the building. Its public areas, bars, food hall and the Connie cocktail lounge in a restored aircraft are open to anyone, two of the food outlets run 24 hours, and it is all landside, so a long layover can be spent there instead of in a terminal seat. The TWA Flight Center guide covers the building, what is inside and what the pool and observation deck cost.
Showers, food and getting through the night
A shower. The airport is blunt: there are no public showers at JFK, and it points you at airline and credit card lounges instead. Four Terminal 4 lounges list shower suites in their airport entries, Capital One, Chase Sapphire, Emirates and Virgin Atlantic, and Terminal 1's Korean Air Lounge names one too. If none of those opens for you, the one shower at JFK with a published price is landside: TWA Fitness at the TWA Hotel sells a $25 gym day pass that includes showers and the changing area.
Food. Covered above by terminal, and the short version is that only Terminal 4 solves it properly. The food guide has the hours for every terminal, including which places open at 3:00 and 4:00 AM if you can hold out.
Your bag. Carrying everything around all night is the worst part of an airport overnight and it is avoidable. The Terminal 4 storage desk is open 24 hours and takes bags from passengers flying out of any terminal, at $25 for 24 hours. The luggage storage guide has the rules and what you need to bring.
Power and connection. Wi-Fi is free and airport-wide and holds up overnight, but the retail that sells a charger closes with the terminal, so charge before things shut rather than after. The Wi-Fi guide covers where the charging points are.
Two last things. Pack a layer within reach rather than in the checked bag, because nobody is going to hand you a blanket. And there is no smoking anywhere inside, with every designated area outside the building on the public side of security, which is a longer errand at 3:00 AM than it sounds: the smoking areas guide explains why.
