Well, you should have known in which difficult financial situation US Airways is (itīs much worse than that of their competitors).
And just tell us how much you paid and ask yourself what you can expect for that amount - i know the pricelevel between Germany and the U.S.!
(I live in Schwetzingen which is just "next door" to Heidelberg.)
Somehow i understand that staff motivation goes down when salaries are cut...(it should be no excuse, though)
This makes it even more difficult for US to survive as it wonīt take long till regular US customers start looking for better U.S. airlines (if there are any...).
Unfortunately i have to consider US as a hot candidate for the next "big" failure on the U.S.market. Never flown on US but they still have a positive image to me especially as they really tried to renew their fleet rather than keeping oldtimers in a somehow airworthy condition like most of their rivals!
Just wondering if your miles wonīt get lost if they "cease operations"...
