No tricks I know of-- I am stuck here in Providence. Well, I live here, but I certainly did not want to be here this weekend!
One thing I did all day was call UA Reservations (faster than waiting in line at the airport, even the Premier/First Class line) and have them protect me on different flights. First my flight was delayed, and it would have meant missing my connection, so they protected me on the next flight out from the hub. Then in case my flight was cancelled (i was pretty sure it would be, with the amount of snow), they protected me on the next available flights-- unfortunately they were for SUNDAY!
But upon returning home I checked ITN.net and found that there is a new flight operating out of PVD tomorrow-- a 737. I have no idea where that equipment is coming from, since UA has not been flying them in lately and none was scheduled for today. Perhaps a flight that diverted?
