My teenage daughter arrives at Terminal 4 on ElAl at 3:55pm. Does she have enough time to make a JetBlue flight to Dulles from Terminal 5 at 6:00pm? These are separate tickets and she is an American citizen. I assume she has to go thru customs then re-check. She will have 2 large heavy bags plus carry-on, can she take a luggage cart on the train between terminals? Is 2 hours enough time? Thanks for your help.
