So I'm an idiot. I booked a domestic flight yesterday using a flight credit that I had from a cancelled trip last year. When planning this, I stupidly thought that I could use the credit (~$680) to cover the costs (~$250) of both my ticket and the ticket of the person I'll be traveling with. Of course the Expedia agent cleared up my misunderstanding quite quick, but I figured that the $150 change fee cost for my ticket was still coming out ahead. So, I booked my ticket using the credit, and then went and booked another ticket for my companion. I then went in and made sure the seats were what we wanted. I called US Air this morning and was told that there isn't any way to link the two trips, such that they become a single reservation. I'm pretty sure I can get my companion to be able to board with me in the Zone 1 group without too much trouble, but on the off chance I get upgraded it will be a bit annoying. My questions: 1. Was the US Air person correct, or is there some way to link the two itineraries that I'm not aware of? 2. If I manage to get upgraded, will anyone get their nose bent out of shape if I switch seats with my companion? I have never tried to switch seats across cabins before, and sitting in first would mean more to her than to me. Thanks.
