Very helpful staff especially when helping with the missing baggage

The seats are so close that you have 0 room to move. Not acceptable for an 11 hour flight.

OK overall. Flight was delayed Crew on flight was good

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.

Excellent long haul experience really enjoyed using Dublin pre-immigration

they couldn’t not serve coffee or tea as the water that was boarded was not potable. the veggie food was lousy. tasted very sweet. there was a crying kid a few rows ahead. what about the difficulty caused to other passengers because the kid was crying so much. parents should know their kids better and not travel. it was a very difficult situation. would not recommend this airline next time.

The flight was over two hours delayed. The aircraft was somewhat dated.

Great to have power available for every seat in Premium Economy. I do wish the WiFi was less expensive. It was 23-24 Euros for the flight for one device. And there were times it was unavailable.

Alaska located my mother, aware that she had mobility issues and they seated her closer to the door. She and I were seated together so I felt more secure to be able to assist her. The desk attendant reviewed what steps to take when boarding. Allowed us to board first, we loved that. I was allowed time to help her board slowly, seat her, put all her things in their place before the crowds came through. These small details made me want to travel Alaska more when possible.

I originally chose two aisle seats for my daughter and myself in the same row. We got seated in the middle, three rows apart. Both of the men sitting in front of us reclined their seats fully leaving us NO room. A totally uncomfortable flight for eleven hours.

The economy seats had space unlike Iberia Airlines from NY to Barcelona.

Iberia canceled then rescheduled the first leg of this flight three weeks before my trip left on May 11. I had to cancel and get a refund. And scramble to find a different flight through a travel agency flying on United. And Kayak , you’ve been writing me ever since as if I’m still on this original flight! Pretty scary you have no way of knowing what has befallen your customers! I will never buy plane tix from you again!

The flight from Amsterdam to Dallas was great, ok food, good service, great entertainment. But Dallas to SF was very tiring because of two hour delay inside the airplane waiting for AA paper work in 99 degrees in the sun. We had no oxygen and the pilot had to ask everyone to blast the AC because it was getting too hot inside the cabin.

Food was low quality as well as quantity; I ordered vegetarian. We waited 35 MINUTES for the first bag to arrive after landing.

We had a seat that would not function. No Wifi or inflight entertainment was available. Food was very poor. Attendants were very accommodating and apologized for the problems.
