I am going to Mexico in two months and the best flight itinerary I can find is on two separate airlines, taking US Air there and Mexican Airlines back.
First of all, is this allowed considering it is an international trip? Second of all, will it cause a hassle at check in and then again at customs if the computer doesn't show that I am planning on returning to the US?
It's a short trip, I'm only going for 5 days, and I am planning on printing out my itineraries so that I can show that I am departing in a few days.
Thanks in advance for any advice, it is greatly appreciated!
