I use US as a second option and I've had good experiences with irop and US accommodating me. For instance, last time UA was late arriving into LAX (from NRT) and I had a separate US reservation LAX-PHX-TUS, I missed my scheduled flight. I expected the riot act but when I presented apologetically at the LAX T1 rathole, the US CSR was most helpful, first standing me by for the next at no charge and then at T-30 confirming me with BPs. Actually, they put me onboard, and then upgraded me! My UG was taken away at the gate when the GA asked me if I was Gold on US, or just Star, and when I confirmed Star, she apologized and downgraded me. I had no issue with this, since I had not expected and was not entitled to such UG. I was prompted to write this by reading the BA board over on FT and seeing comments like this: "US Airways looked after me very well a few years ago. The CS staff were wonderful, and all my non flexible / non refundable flights were changed to whatever I needed with no fees and I did not have to pay the fare difference" Although US doesn't meet my needs for program and coverage, which is why I stay with UA for my primary affiliation, I've had good CS experiences with US as a dirt member. I find them better at that level than most other airlines and especially BA, who as the poster above noted, were a nightmare for soft product. As a dirt member, UA doesn't do as much for its flyers.
