I can't believe that '**** happens' is an acceptable or appropriate response and I doubt very much anyone directly affected would take that view whether or not they use social media.
If a flight is cancelled for good reason, that's one thing. But the airline is required to either refund the ticket or make alternative provision for its customers including consequential costs such as hotel accommodation.
It's a pretty poor attitude if a multi-billion pound industry wrings its hands and takes a 'Not my problem, guv' stance.
