US Air is Worse than Words Can Describe

Its 4:45 pm, I was scheduled for a 3:10 de3parture. They delayed boarding the plane for 25 minutes bc they had to wait for a part to fix the AC. When I got on, it was hot as hell...mind you it is a balmy 110 or so today in Phoenix. I sit on the plane for a good 10 minutes & they say that we will be running with only 2 AC's today instead of 3 bc they couldn't fix the one. Wonderful....oh wait....no....10 minutes later they tell us we need to unboard bc one of the two they were relying on IS NOT WORKING! So...off the plane we go. Sit in the terminal for 10 minutes or so & then reboard. Being informed that they can't fix either of the broken ones, but that we can run with only one, but will probably have to stop to refuel somewhere. My patience has run out, I need to pee, I'm hungry & I just want to go home!!!!!
