Lack of common sense policy...
I've flown US Airways 27 times in 2013 and put up with lots of little imperfections as overall I enjoy flying their service. However, I will be finding a new airline for 2014 (too bad I have 5 more flights booked/paid for this year).
Bottom line I decided to drive from Phoenix to Palm Springs with a friend instead of flying on my reserved/paid for flight. No big deal - I just wasted a few $ and instead drove. It's not the first time I've not flown a leg of a round trip ticket on US Airways.
Imagine my surprise when I found out they cancelled my return flight to Phoenix. I didn't panic, just called them to have it corrected. The very nice customer service person said no worries, he could get me on the flight. Short term relief.
Then he said "well a new flight is less than the $200 change fee." I replied that's ok, I already paid for my ticket. He said that wasn't their policy blah, blah, blah. (I decided to be nice, he's the messenger, not the policy maker).
Unfortunately that is the flight I must take in the morning or I would have booked another airline or rented a car or ridden a train if I had to. Instead, US Airways charged me a 2nd time for my ticket home.
That is offensive. Southwest here I come!
