Regarding change of equipment--it happened to me this week from DIA to Tampa. The flight was listed on the monitor as on time, but UA said it was "on decision." I love the advice to "call again just before you leave for the airport." Do you actually know anyone who can leave home less than an hour and a half before flight time and CHECK IN the required hour before?

Anyway, when I gave the Red Carpet rep some flack that the monitor still showed it on time, she told me that the CITY runs the monitors, not the airline (I have to believe that they get the info from the airlines, though).

Apparently UA brought another plane and quickly serviced and boarded it. As usual, we were kept hostage at the gate because the flight was leaving "momentarily." Not without a plane, it isn't.
