USAir has done it for me twice now. As recently as... yesterday.
I'll admit I stretched the truth a wee bit but it was just because of what the OP said-- they weren't being friendly. If I wouldn't have gotten so mad (I've got a temper and a half) they probably wouldn't have refunded them.
I didn't really think they'd do it when I called, but thought it was worth a try.. (I wanted to rebook with the amazing SW Ding! fares out of Columbus, yesterday.)
So I called and acted like I had no idea how the travel industry worked. Explained that I'd recently had surgery (true) and had been to see my doctor this week (true) and that we had discussed how well I was healing (true) and wasn't sure whether or not I would be ready to take my upcoming trip. (not
really true. We were talking about my July trip, not the September one which is what I had booked USAir for)
I was really nice about it but then the lady LAUGHED at me and said "What exactly is so wrong with you that you already know you can't make a trip three months away?" and I'll admit it, I lost it a bit. The specifics of my condition are not important. If they wanted something from my Doc, fine. But it's not important as to WHY. Then she went on to explain to me that they had no medical clause so it's basically not her problem. If it hadn't been for her attitude, I would have just said "Thank You" and hung up.
But I couldn't let it go. I got really upset with how cavalier she was being. I told her that the specifics of my condition were absolutely none of her business and that
generally when one has surgery they hope that all goes well the first time (it did, I'm fine, just still having minor, minor problems) and that they don't really like to think about it getting in the way of the vacations that they have booked six months away. She started in again with how they have no medical policy and I was like "You know what? Thats fine. But I think you should look at my account (dividend miles member) and look at all the flights I have flown with your airline (enough in the past 2yrs to qualify for more than a free ticket!) and be more understanding for people when their lives don't go specifically the way that they PLANNED them to go! I have been nothing but nice to you and your attitude has done nothing but offend me!" and she got quiet and said "Let me talk to my manager"
..came back on the phone and offered me a full refund back to my CC..
(So I ran over to SW and rebooked us BOTH for less than the original price of one ticket on USAir)
