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

The boarding process was a disaster. No one respects the boarding groups—tired old aeroplane. There are no sockets to charge phones. The cushion seats are ancient and hurts back and gluts

My selected seat ending up being very uncomfortable both major flights. SFO to London and back. Seat arms did not go up so it was not like suggest by BA staff. On return flight my seat had a life raft barrier in front off me and large man beside me.

No food as per my diet restrictions even after advance request and delayed baggage without any notifications

The flight was fine. Unfortunately, the seat entertainment (movie/TV/game options) was malfunctioning for some reason, so movies weren't an option on that flight. On the flight to my destination, it was working all right, but I never used it because I couldn't figure out how to make it work. It would be helpful to have better instructions for those of us who aren't too skilled at such things. Other than that, no problems. The crew were courteous, the food was decent, and they got us where we were going on time, or even a bit early. I would use them again.

My ticket was cancelled unannounced and I was left stranded in the air port

It was the most uncomfortable flight I have ever had , it was a nightmare ,the seats were narrow and I was very cramped, the food was awful, there was over weight person seating next to me or should I say seating on my lap.Most of her was overflowing onto my seat .For 6 hours I endured this gulag like conditions. I will never ever book any flight with British Airlines

Awful flight. My pre-booked seat was given to a crew member and I was substituted with an awful seat next to the toilet. When I asked about it I was treated with contempt for daring to ask. Par for the course on BA at present.

Superb staff, ingenious seating in Club class. Superb food and service. Loading and unloading. Ample cabin overhead luggage space. But the earphone socket was damaged and did not give binaural audio. Very hard to follow a film over the engine noise. Nor could I get to play Sudoku for want of instructions.

The crew is excellent. However there are a few things that are not satisfactory: seats are smaller than many other airlines in economy, food was sad and I had bad diarrhea after I drank a cup of tea, They also forgot mine and many other people’s luggages somewhere this time. The luggage was delivered two days later, which caused a big inconvenience because 1. Most of my son’s clothing are there and he had to go back to College before the luggage was delivered. Now I will have to mail his stuff to him; 2. Two pairs of shoes are missing from the luggage.

You lost my luggage on the trip to Dublin and again on the way back, still waiting on luggage.
