So what happens to the concept of "getting what you paid for"? Does KLM just shrug and say sorry? I could imagine if they said "we can't pay for accommodation but we'll send you on the next flight", but did they even do that?
I wasn't anywhere that needed accomodation so I cant speak to that. They canceled the flight and booked for the next day, which meant that I had to miss half the conference and the reason that I was making the trip in the first place.
