My Ryanair Knock (County Mayo's international airport) to Manchester flight was delayed by some hours, a few years back. A soft Irish voice came over the PA: "If you lads want to go to the bar, they'll fix you all up with a drink and a sandwich, if you show your boarding pass - after a further wait, Ryanair's local manager came out and brought another round.
A customer service ethic, that I think AerLingus might get into!
