With short haul flights being shorter than most Bus Eireann bus journeys and prices similar, why would you expect or need the service to be any better than that on a bus journey?
You buy a ticket, turn up on time, get on the plane and sit down, fly, get off the plane and leave airport. Sometimes planes are late, but so are buses. I no more need someone to serve me an over priced dinner or patronise me with a make-up caked false smile on a flight than I do on a bus.
