if I travel within USA is it ok, although I have a green card & an US I.D., to travel with my italian passport in order anyway to accumulate miles even when I travel within USA? Or at the airport they might ask me why I travel around USA with my italian passport instead of using the US I.D.?
I hope my question is clear!!!!! Has anynone traveled within US with the passport of their own country instead of using the US I.D. in order to accumulate miles? I also hope I wrote my topic in the right section, if not sorry about that..........
Thanks to all who might give me a reply!!!!!
