IME it’s very difficult getting money out of Ryan Air, earlier this year we also had a flight from LBA that couldn’t get in due to high winds, plane diverted to east mids so we were transported there by bus, eventually got on the plane after we were all reissued new boarding passes however the plan went tech just prior to take off, by the time it was fixed the crew ran out of hours. I agree the initial problem was weather related but the mechanical and crew issue were not, even involving a specialist claims company we were not able to claim for anything.
