I booked flights on US Airways for me, my wife and my 4 year old son on Orbitz.com. (This is a dual rant against orbitz and US Airways.) There was no mention that the lowest fare quote they gave me was for three middle seats (US Air apparently charges more for aisles and windows -- total BS). When I arrived at the airport they told me that we had 3 middle seats -- meaning my 4 year old son would be sitting on his own next two two strangers. The US Air ticket agents said check with the gate agent. The gate agent said check with the flight attendants. Then when we were finally on board, the flight attendants said, "We are not allowed to re-seat passengers, or ask passengers to switch seats." Why couldn't they have mentioned this at the ticket counter or online or at the gate?? We are on the plane at this point, my 4 year old son is totally distressed sitting in a row by himself as the other passengers file onto the plane. Thankfully a guy next to my wife, who had probably paid extra for his aisle seat, was kind enough to switch with my son. I can't imagine this is the first time US Air has had this happen and its unconscionable. This is the most poorly run airline I have ever flown on, and I will pay extra to avoid it in the future.
