The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

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

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Very good need to offer better choice of food for business

Economy class has no legroom so if you have the money worth to upgrade! Food was absolutely horrible! The crew was super nice!!!!!

The flight was provided by Aer Lingus and our seats were in a poor condition (15A & 15C). They looked like they needed repairing/replacing and were uncomfortable for such a long flight. Also the arm rests on Aer Lingus planes do not lift more than around 45 degrees, instead of the usual 90 degrees upright, meaning you cannot maximum the space between you & your travel companion so as to be more comfortable for such a long flight.

Very bed boarding, there was overbooked and make a lot of problems and noises

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

Boarding poor in London,ok in Chicago. Don’t like Heatrow/terminal5

It was very good. We got a late start by about an hour and a half. However I worked rather have that than crash. It was purely mechanical. They had our tickets ready when we came off the plane in London for the next leg. The only mishap was when we got to Lisbon my husbands luggage made or bit mine didn't. All was not lost because I did finally get it 2 days later. I was really pleased that they c made the effort.
