Hi I am traveling next week to Italy and I am flying from Columbus to JFK on American Airlines and then I am switching airlines to Iberia at JFK to go to Madrid and then to Venice, so I am switching from Terminal 8 to Terminal 7. I booked everything through American Airlines--I guess they have a partnership with Iberia. I wanted to check a bag. If I check a bag at my original destination in Columbus, will I have to pick it up at JFK since I change terminals and re-check so that it goes to Venice or can I simply check the bag in Columbus and be done until I reach Venice? I only have a 2 hour connection so I am concerned about the time. Also American Airlines and Iberia are part of the OneWorld Alliance. Thanks in advance for any help!
