I'm sure FR are fine in when everything's going to plan, but if this is what the 'new' Ryanair is like in IRROPS at one of their home bases, I think I'd rather still avoid them.
Presumably the passengers are due their EU261/2004 compensation for the delay, but is there any redress for the apparent complete lack of duty of care by the airline?
(also, would having a US-style Tarmac Delay Plan have been any help here?)
