Hello, I'm traveling on July from TUS-ORD and then from ORD-NRT with AA. The problem is that the connection time is 1 hour. Will I make it? Luckily, the domestic arrivals and the international departures for AA are in the same gate. I'm new to connections in flights. Will I have to pick up my luggage and register again? Or the luggage changes from plane to plane? All the info you can give me will be helpful. Thanks.
