I've had four overnight delays on three transatlantic trips this year. Fortunately, EU passenger compensation rules applied to three of them; the airline must pay each delayed passenger 600€ or convince them to take a more compelling non-cash offer.

I'm not for heavily regulating non-safety details of how most industries do business, but I do think it's fair to demand the true price up front and compensation when the airline doesn't provide the service it sold for reasons within its control.

Right, I've had train companies put me in a taxi, and just eat the price of a taxi to wherever because if you want to sell tickets to travel to X, and then oops you can't get me to X well, I didn't buy your "regret" that you can't do that - I bought travel to X, so if that's still possible you'd better make it happen and too bad if that's not profitable.

There was a year I made more money from flying than I spent, because I kept flying ryanair or easyjet and I kept getting massive delays (one was a 20h delay, in which I spent the night at the airport squatting some of the couches in a cafe in the terminal, because small delays kept being slowly pushed on us, and we also spent 2h waiting in the final plane for it to take off, no A/C and they refused to give us water threatening to call the cops on us if we did get water bottles ourselves, great experience!)
