Would have been nice to have a plane that was equipped with a screen to watch a movie enroute to Barcelona, but all good. Flight and crew was excellent. Much appreciated the updates from captain and Kayak about the flight delay due the weather. It’s nice to be kept informed. Will Aer Lingus for future flights, and definitely through Kayak
