May 2009 Airline Traffic Numbers

(MoneyWatch)  May traffic numbers are in, and most airlines saw load factor declines for the month. US Airways was the only real exception. (I don't even count Allegiant anymore since they seem to be competing in a different universe with their stellar results.) This was certainly a tough month for most. Click for definitions.
