International Flights from USA to Europe
This October 25th, we are flying from Chicago O'Hare Airport to Barcelona ,Spain to go on Liberty OTS for our first ever transatlantic. My question is about the flights, on American Air Lines. I've waited on the phone for,it seems, hours to try and get an answer, but I'm getting older by the second, and may forget what I wanted to ask if I have to wait too much longer.
Our flight leaves O'Hare and flys to JFK in New York. We then sit there for an hour, before we switch planes for the last leg of the flight to Barcelona. For those of you who have flown out of O'Hare to Europe, O'Hare has two terminals, one domestic, and another international.
Which terminal do we check in at, domestic for the first leg of the trip, or international for the ultimate destination?
