Ok, so here is the issue. My girlfriend is sitting on United 1148, that was supposed to go from ORD to BUF at 1941 CDT and still hasn't left for various reasons. Meanwhile, they couldn't find one of the pilots rostered for the flight, they taxied out over an hour ago, had the AC packs go out, went back to the gate to get that fixed, had to load extra fuel for a low and slow flight, and have now had the F/As time out. They apparently have found 2 reserves but with another flight (UA254) sitting around waiting to ply the same route, you have to wonder how many people they have with duty time left over to go around. Mind you, this is after her DEN-ORD (itinerary was BUR-DEN-ORD-BUF) had to divert to RFD, had a mechanical there, and finally got into ORD only to see her miss one flight and now have this happen.
At what point does United just cancel this one and eat the hotel costs?
