I've seen that too...

had one transcon delayed for a few hours and now there is no way we can legally do it. Watch them change it from T5 to T4 and Back to T5 again. Pax really happy. Then it cancels and we get assigned to a ferry flight in crap weather. We get to the gate PD and angry pax at the transcon gate. We board the ferry flight and the agent is standing in the cockpit telling us we have to move fast he needs the gate....SMH

capt asks the agent to step and tells the plane will leave when we get fuel and are ready and then shuts the cockpit door...
