Flight was canceled and rebooked for 25hours later. At transfer point, baggage was lost - still waiting to hear word 3 days later. The flight itself, when In the air, was smooth and crew was fantastic. Just too many issues leading up to flying that make it hard to recommend Aer Lingus.

A drink would be appreciated at least. Drop off by bus at Dublin Airport was miles away from terminal 1 for an old somebody to walk carrying luggage

Electronics are old. To Ireland and back had to have crew restart the movie screens multiple times. Love the 2 seats next to each other on the sides. Crew very accommodating and also frustrated with old electronics.

Not enough staff at check-in gate. Very slow moving line. Flight crew was great. Everyone of the staff were very nice and helpful.
