Good morning John,
You were talking about the amount of time people have had to wait for planes, well I've never had to wait for one, but that's only because I've never been on one.
I do remember one of my teachers telling me a story though about one time she was going to catch a plane from Melbourne to Canberra on Christmas Eve, while she was waiting for the boarding call in the waiting lounge she was having a chat with a pilot and mentioned that she was going to Canberra, the pilot told her that he was too, and she was going to be the only passenger on the flight, she could have any seat she liked, but she would have to sit right down the back with the flight attendants during take off and landing to balance the plane!
Apparently they would have cancelled the flight, but as it was Christmas Eve and they needed the plane in Canberra for another flight, they decided to go ahead with only one passenger. My teacher said it was the best in-flight service she has ever had.
Have a great morning,
