I was going to book in December for a Stansted to Titograd flight, but with this nonsense, I won't be.
Travel insurance won't recoup the costs if a cancelled flight is the fault of the airline, so it will be a messy wait for people to try and recover fees from Ryanair and from when I used to work in travel insurance, they make it as hard as possible - call centres in Ireland on premium numbers with endless waits.
I remember, must have been back in about '06, during a baggage handler's strike in Spain, they told passengers they just had to abandon their bags at the airport and wouldn't check in anything above hold baggage size. Because the bags were not checked in, they were not Ryanair's responsbility, so they would not be forwarding them on, they were just gone.
