I have a flight with Iberia from Spain coming into JFK (New York - JF Kennedy) Terminal 7 at 9:15pm, and because of a change of plans I need to book a flight to Atlanta from there. However, there are no such flights departing after that.

If I book a Delta flight from T4 for the following morning, could I just check my bag all the way to Atlanta from origin, and go into the airside of Terminal 4 at around 11:30pm?

If that's not possible I could also transfer to LGA (New York - La Guardia) and fly to Atlanta from there the next morning. Which airport's landside area is best for a layover?

Will airport security have a problem with a 17-year-old sleeping there overnight?

    The quality of JFK is very terminal-dependent, but sleepinginairports.net may be a help.

  • For the first part, I think the answer is no. Iberia and Delta are in different alliances, so are unlikely to through-check across two different tickets. Iberia to American would work though, as those two are both OneWorld

  • @choster: When I overstayed the night in Terminal 1, I could not find any place/lounge to rest. Granted, I didn't do my research before, and there may be possible options.

You can certainly stay at the airport airside or landside as long as you have your belongings and boarding pass available for inspection. This topic has been discussed on Flyer Talk before.

Personally the comfort level in both LaGuardia and JFK overnight is about the same for my liking but I'd just stay put just so I don't have to pay for the cab or a bus.
