I just booked a US Air flight to Savannah because Delta was double the price. The US Air website is very frustrating. It was very slow. When I was at the point to pick seats, it would not allow me to pick a seat for my husband. So I confirmed without him having a seat assignment, figuring I could go back and change it after the reservation was set. I tried to do that. The website shows that I do not have any itineraries. The only way I could find my flight was to put in the confirmation number. Did that, and again tried to select a seat. Still would not allow me. So I called US Air, and spoke to a very abrupt representative. He told me that the seat next to me was booked, Row 5, and that he had to put me in the back of the plan for the next available 2 seats together. I argued with him that the seat next to me is open according to online, as was the one I had just picked for myself. He did not want to hear it. Whatever. I told him to just put us in 2 seats next to each other. I then go online, and my original seat in row 5, and the seat next to where I was are open. What the Heck! I tried to change it online. I was able to select those seats, but it would not save them. The moral of the story, the US Air website is a pain in the neck.
