This is my first time flying back to the US since I moved to Italy. I thought I had the passport question straightened out, but after reading an old reply, I could use some clarification.
Question #1: I booked a r/t trip to the US and put in my US passport info. Since I'm traveling r/t, would it have been better to use my Italian passport info? Does it matter? If so, perhaps I can change it.
Part 2: Do I show my Italian or US passport when I'm at the Airport in Milan?
I assume I'll reverse the process it when at the counter in the US.
Thanks so much. Hopefully, this will help to ensure a smooth flight. (-:
