Mom and my little sister were supposed to go on a cruise over Christmas. The first leg of their flight to the embarkation port was cancelled when a door wouldn’t close. The storm in the midwest, and the consequent meltdown of the North American air travel system, put paid to any chance of getting re-routed. So they didn’t go.
The door that wouldn’t close on the first flight wasn’t an outside door, it was the cockpit door. Mom was peeved. Most people would have complained about the security policy that prevents takeoff without a locked cabin door. Not Mom. Her take was that there were lots of security guards around the airport, and that they could have just got one to stand in the doorway for the flight.
