Standard & Poor's has removed US Airways Group Inc.'s corporate credit rating from "CreditWatch," saying the airline is expected to report "much improved" revenue in 2010.

US Airways is the dominant carrier at Philadelphia International Airport.

S&P analyst Philip Baggaley affirmed US Airways' "B-" corporate credit rating, but noted the carrier had deferred most 2010 aircraft deliveries.

A combination of "reduced capital needs for aircraft" and "an improving revenue outlook" should help operating results. US Airways' ratings had been on CreditWatch with negative implications since July.    - Linda Loyd
