One thing that we were upset with, was that there were plenty of empty seats on the flight. We asked the flight attendant whether we could move to one of the seats and she said that we could after take off and the seat belt signs were off. There was also an announcement saying that people jostling for seats would be punished. However, after the seat belt signs were off, when we went to the free seats, people had just decided to move there without asking for permission. The flight attendant didn't even acknowledge our request and didn't mention it to us again. That was disappointing.
