tlv - phl 1/26 11:30 pm, us airways. Figured would have problems so switched to flight on 1/27. now I'm thinking that the flight mon nt may get out, but being as usairways only has 1 flight a day, if the mon nt 9:10 pm flight from philly is canceled they are not going to have a plane here tuesday nt 1/27, effectively cancelling the 1/27 flight even though by then would be ok to land in philly. is that a reasonable assumption? should i try to get back on tonights flight?
