I have a flight from Raleigh-Durham via JFK/New York to Incheon, South Korea. It's JetBlue from RDU to JFK and Asiana from JFK to ICN. I only have 2 hours layover in New York and I was worried about making it on time. I know JetBlue and Asiana have a codeshare so I assume that my bags will just be transferred to the international flight at JFK without me having to check them in again. However, I am concerned with travel among the terminals.

Is there secure travel between the terminals so I don't have to leave, check in, and go through security again at the international terminal? Or do I have to do that?

  • You probably don't have to check in, but you probably do have to change terminals, which means going through security screening again.

    Could you edit your question so it's comprehensible to people who haven't memorized every airport code in the world? Jul 3, 2017 at 21:01
  • I taken the liberty of changing the layover to New York/JFK, instead of what you had, Raleigh Durham.

  • Asiana and jetBlue interline, but I do not believe they codeshare.

In order to go between terminals 5 and 4, you'll have to take the AirTrain which means leaving the post-security area. That said, 2 hours should be more than enough time to leave your gate, take the train, and go through security and catch your second flight. I wouldn't be concerned unless your flight gets delayed.

Disclaimer: I've not been through JFK too many times so it may get more crowded than I've seen it.
