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

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

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

American was good / British Airways partner was not as good…

Both flights into and out of Heathrow were delayed over two hours due to BA technical problems. Ground crew was not very friendly. However cabin crews were

Terrible seats. Cabin crew were the only good part of my BA experience.

The mobile app for BA could have been better. It did not update real time on gate chnage information at the airport.

Positive boarding experience, easy access to seat with plenty of luggage space

Flight staff was amazing! They deserve a raise. Middle seat was very uncomfortable

This flight had seats that were more comfortable than the trans-Atlantic flight I had come on. Boarding, however, was atrocious. There was no point in boarding groups since everyone ended up on the same bus to get on the plane. And the bus ride took forever to get to the plane. The snacks can barely even qualify as snacks. Make sure you bring your own or eat before getting on,

My flight to rochester got cancelled and they booked a hotel for me which isn’t good at all. And they said i will be a standby for next day flight so they still not sure which is horrible cause i have a lot of arrangements. I don’t think i will book with this airline again
