True; USAirways has suspended lease payments temporarily.
US 330s fly a variety of trans-atlantic sectors only. To my knowledge they never fly domestic. I know they fly CLT-LGW, PIT-LGW, PHL-LGW, PHL-CDG, PHL-FCO and PHL-MAN or FRA. Mostly, they're based in PHL, but occasionaly they fly out of other hubs, CLT/PIT.
