Short flight so not much to rate. Surprised I had to pay for a soda.

Short flight so not much to rate. Surprised I had to pay for a soda.

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.

Very good need to offer better choice of food for business

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

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.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

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

Excellent long haul experience really enjoyed using Dublin pre-immigration

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

Excellent. Very nice and comfortable business class. Only negative is that it was difficult to hear the pilot’s announcement.

Air hostess delayed providing food and then pulled away the tray before i finished eating

Not connecting flights. Missed my flight from Dublin to Liverpool because I arrived at Dublin one hour too late. For this mistake, they offered me a flight from Dublin to Manchester. Thats great and all, but I waste time and money to commute to Liverpool. Be sure to check the time of your connecting flights, because they sure don’t when they sell it to you

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.

Not sure if the crew were experiencing something unknown to me,but the service of passing water was non-existent.In addition,please take consideration when providing yogurt as alternative for breakfast as some of us, could be lactose intolerant.. thanks

To take off on time but warned about a possible delay by enail which was good

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.

We were kept waiting at the gate for 2 hours without explanation
