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?
