To Yelp readers - Avoid this airline. On a recent trip, I was denied full access to my seat (middle passenger encroached on half of my space, creating an intolerable experience and safety hazard. Not only did U S Airways not make alternative arrangements, but refused a prorated refund. They spent more in capital and staff expense \"defending\" their indefensible position that the cost of the refund and created some poor advertisement as a result. A brief Facebook scan reveals many other complaints. I note several similar complaints on Yelp, also.
