Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

Great customer service. Frequent updates from the pilot. Smooth flight. Good entertainment. Meal service.

Everything went well, but could have used a bit more legroom.

Long unexplained delay, uncomfortable back row, long waits for trash collection.

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.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

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.

Firing with British airways leaves me feeling stressed and disappointed. They are substandard in so many aspects of airline travel.

They denied us boarding on our scheduled flight and experienced significant disruption to our travel plans because of overbooking the flight!

My flight out of Miami was delayed by 2 hours which meant I had to quickly make other arrangements for pick-up in Glasgow. A $9 voucher for food was issued. That’s not much of a gesture in my opinion.

Our first flight was cancelled and we were rebooked on a later flight. Our second flight was delayed by 3 hours but nobody told us anything. We were just expected to wait at the gate. No notice or information. We ended up missing our next flight from London but because we booked separately British Airways won’t do anything about it even though we booked our flights with more than a 7 hour gap. We had to then rebook new flights two days later and stay longer in London.

Didn’t even get on the flight!! BA had a system crash and knocked many peoples boarding passes back for the connecting flight which we all would have made but ended up missing due to being refused past the barrier. There was one member of staff on and when he shift swapped the new staff member called us liars and that we were going to be too late for our flight hence the knock back which was false. I was an hour and ten minutes early for my connection flight at the time of scanning the boarding pass. Waited for three hours and ended up having to book a train home myself which was 4 hours long! Staff were useless and entire experience was an inconvenience. I had been travelling for three months and of course it was when I was back in my home country that I had the first muck up! Will not be touching BA to fly again

why couldn't BA confirm my flight from Milan to Phoenix on AA

I’ll fly with any other airline. Besides all the fees and not being able to change a flight even to a later flight without paying £150 charge. Or that the last flight the WiFi didn’t work, the food was so bad, and ran out of options. Seat didn’t recline. And the headset jack didn’t work. This isn’t my first flight with them, and on every flight there is always something wrong that makes the long 10 hours feel like an eternity. Never flying them again.

On this flight I was in BA business class. I am used to flying United Airlines Polaris class and I was underwhelmed by BA’s business suite class. A few things: - the lounge at LAS was very basic and crowded and the LHR/T3 lounge a bit better, but still not like the Polaris lounges - boarding was chaotic, no one knew what group was supposed to board - the suites were nice, but the padding was not really made for sleeping on - crew were friendly, but only really one tray/serving for the dinner service. None of “drink first, then dinner with 1-2 pourings of wine, then dessert”. UA might not be known for the best service in the industry, but compared to BA they are super attentive. During the BA flight there was no one checking in on you after you got your one tray. - arrival at LHR was busses taking us back to the terminal, surprising for a long flight. Once again chaotic. The bus for First/Business was completely packed with anyone who could get on and the driver was screaming at passengers to get every inch packed before he drove to the terminal. By the time I arrived I felt like BA had sold me a superior flight experience and delivered a mediocre economy class experience just because they can and do not really care about their customers. Very disappointing.

Flight left late and we missed our connection in London requiring an 8 hour wait in Heathrow for the next available flight. One of flight attendants was not helpful with my husband’s necessary crutches.

Pretty good flight in general. Connection in London was extremely slow. The security was slow and understaffed. It took 35 minutes to get through and it was not even crowded.
