Austrian airlines gave me credits for the cancelled flight to Vienna after few weeks. I appreciate the gesture - they didnt really have to do it, but it was a nice gesture of them to earn some goodwill of people by giving out credits to people who cancelled their flights to Vienna because of cancelled concert. Now, it’s another matter if I can actually use their credits for another trip within a year. I am sure thats a part of their calculation on how many will actually do anything about it.
