What's with all this talk of bankruptcy? US Airways has been consistently overselling flights. There are numerous paying passengers that don't get on, much less any non-revs. Thank god for the jumpseat!
US Airways has a huge load factor; that, coupled with dog crap labor wages and oil prices less than half of what they were a year ago, the airline industry is looking toward a very profitable 2nd half of the year. Despite the economy, the seats are filled, at least at Airways.
