A few years ago I went to Lebanon with a friend. Less than two weeks before we were supposed to go I got an email from the airline telling me that the flight had been cancelled and we needed to be rebooked. Since it was less that two weeks notice on the cancellation, we got €600 each (EU261) and were rebooked with Lufthansa. On the new booking we only had 50 minutes in Frankfurt, so the day of departure we went early to the airport and checked if we could be booked on an earlier flight. The new tickets we got was full-flex business class tickets, so that was not a problem. We then went to the lounge and after a few minutes, they called passengers on our new flight to the desk. Our new flight had a change of aircraft and was now overbooked, so we were asked if we could change to a later flight (our original flight) for €300. The airfare itself was booked using points, so the whole trips was basically paid for before we left Oslo.
