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.

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.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Great hospitality and service! Seats are better cushioned then some

Great hospitality and service! Seats could always be cushioned better.

Customs is always a challenge. The customs officials were real humans, which was nice-not robots programmed on angry 😊. If you’re in a hurry to get through you’ll be stressed out. Allow yourselves plenty of time and it will be a stress free experience.

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.
