OK overall. Flight was delayed Crew on flight was good

delayed flight stayed whole night at washington Dallas airport at seats , uncomfortable . i am senior citizen , very tired , worst travel.

I love the direct flights. It saves a lot of hassle and allows immigration and customs in Ireland, making arrival much easier.

The space between seats was reduced even further. Could not even open the tray table fully and got compressed the moment the front guy reclined. For a long haul flight it was extremely uncomfortable.

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

I got rerouted to another flight/city because the original flight was late and I would not have made my connection. I had to wait an additional five hours (no compensation) for the new flight which was also delayed because the computer was not working. Arrived at my final destination after nearly 20 hours of travel only to discover that my baggage had not arrived with me. Two days later and still waiting for my baggage. Customer service has been incredibly unhelpful and even hung up on me because I dared to ask for them to have someone call me when my bag arrived at the airport. No one apologized to me for what I experienced and they were dismissive of the fact that I have absolutely no clothes or toiletries. Absolutely awful, disorganized and stressful experience. Am dreading the return flight.

Excellent long haul experience really enjoyed using Dublin pre-immigration
