O’Leary said: “Theres no legislation designed that says any airline getting a fare of €30 should be reimbursing passengers many thousands of euros for hotel accommodation. Its absurd. I dont have a problem with everything being grounded for a day or two but there should have been a much faster response by the governments and transport ministers and by the regulators. This is one of these issues we want addressed – why exactly are the airlines expected to be reimbursing peoples hotels, meals and everything else when the governments are the ones who made a balls of this?”

Fury as Ryanair refuses to pay stranded passengers costs | Business | The Guardian

I’ll save you from my O’Leary rant (two Ryanair flights were enough to ensure that I’ll never travel with them again) but…

I can answer this; yes there is a law. You need to pay.

The worst argument is that he doesn’t have to pay because the ticket was cheap. Ever hear of insurance Mr O’Leary?

Clue: it’s an option when you buy a ticket! It’s so important that you select by default.
