My dad had an F trip to India many years ago, before the EU rules came in. He was going to speak at a conference and they'd paid for the ticket. The plane was unable to take off due to a fault which was apparently fixable. So dinner was served for the F passengers on the ground and he watched a film during it. Then they announced that the problem wasn't going to be fixed. It was now late in the evening and there wasn't a spare plane so did he need a hotel room for the night. He said that he was going home to his own bed thanks. What about rebooking? No point, the conference he was supposed to be speaking at would be over by the time he got there. I think the compensation that he went after was the tier points but I don't remember him getting them.
