I will left USA flying from San Francisco to Madrid stopping on New York. SFO to NY fly is American Airlines arriving to Terminal 8, NY to Madrid fly is Iberia Airlines and left Terminal 7. I've a single ticket so I guess my luggage will be transferred directly between AA and Iberia.
My questions are:
Should I re-check in my luggage?
What the procedure is (if it exits) to go from T8 to T7 always been inside the "safe" side?
Thanks for your answer.
