My family and I were flying from Austin, TX to Phoenix (final destination was Anchorage, AK) on June 28th. We had our 12 year old daughter, who suffers from a brain malformation schizencephaly, with us. She requires a wheelchair to get around in and we gate checked it in Austin. There were two tags placed on the chair. One was for the gate check itself, the other was the full itinerary. When we arrived in Phoenix, my husband saw the ground crew take our daughters wheelchair and place it in a vehicle. Well, when you gate check something, you get it when you get to the next city. Not so much with US Air!! Now, they decided that the wheelchair was going to go directly to our next gate. We had a 4 hour layover in PHX. 4 hours of carrying my 12 year old, 66 pound daughter around. Yeah, I don't think so. So when I asked our flight attendant she quickly jumped at 'we can't speak with the ground crew\" then proceeded to get herself ready to deplane. We took all of our stuff, including our other 2 daughters and my 12 year olds car seat, up to first class where we waited for the ground crew to bring my daughters wheelchair up. 10 minutes later, we were asked to deplane so they could get the plane ready for the next batch of passengers. We waited for about another 10-15 minutes in the terminal waiting for them to bring me her chair. When we finally got the chair, the lady was very rude saying \"Here's your chair\" then walking off. I will never fly US Air with my daughter again. This was completely unprofessional and unbelievably rude.
