Personally, I think this is disgusting behaviour by Ryanair. Why did they let the case get so far? Why didn't they settle out of court? Maybe they really believe that any publicity is good publicity, and hoped to get a few extra sales on the back of it?
I'm afraid this attitude does not wash with the great British travelling public, who believe it or not, still largely believe in good, old fashioned decency on matters like this. This will certainly make me think twice about the implications of flying Ryanair in the future. Sometimes price isn't the only thing that matters.
