So I have another question. My original plan was to fly US Airways from PHX-CLT-LHR. Then British Airways to Warsaw. After speaking to a co-worker that has traveled internationally, she suggested that I just purchase a zed ticket and fly British airways the entire way. What are everyone's thoughts? My thinling was that I would have a higher priority on US Airways since my employer flys US Airways Express. She said it would be cheaper too. I sure hope I am making some sort of sense here!
