US Airways posts 1Q loss on higher fuel costs

Airline earnings for the January-March quarter are pouring in this morning, and a pattern, set last week when the first carriers reported, has developed.

 PHL's  biggest player, US Airways, had a loss that it blamed mostly on higher fuel costs, despite its improved service. Delta also reported a loss today, and from last week a report we had not posted here yet, United Continental Holdings also reported its share of red ink.
