Food was low quality as well as quantity; I ordered vegetarian. We waited 35 MINUTES for the first bag to arrive after landing.

Food was low quality as well as quantity; I ordered vegetarian. We waited 35 MINUTES for the first bag to arrive after landing.

Ability to select seating would be nice. We were family of three and they had us seated back to back and one of us on the other side of the plane??? That is pretty goofy. Especially when tickets were placed two months in advance.

It was not Iberia. It was with United. It was great!!!

Pretty fair for the price of the plane ticket. Food was poorly, but overall was a ok experience for a super long flight.

Our flight was delayed by 2-hrs but I understand it was beyond the scope of the crew members

I am quite satisfied. The flight was on time and landed early. Staff was friendly.

Overall was good except for the seat which, for an 8 hour intercontinental flight, was uncorfortable. For that kind of flight seats should have more space, even for economy seats.

Booked with Iberia but flight was with Level. This switch of airlines was not published anyware and I was not made aware. Service was horrible, attendants were rude and nowhere to be found. Interior of plane was disgusting and dirty, trash on the floor, bathrooms were dirty (probably because flight attendants were not collecting trash from passengers). I have never encountered this on any other flight or airline. A public bus or metro in Los Angeles is 10 times cleaner. Had I known this was not an Iberia flight I would not have booked this tickets.

Iberia subcontracted the flight out to Level (?). I would never fly Iberia/Level ever again. Old planes with no tv’s or wifi. Barely edible food. Small seats. 10/10 don’t recommend.

Original flight was cancelled - After waiting 2 hours for new take-off times. Then had to stand in line for 3 hours, ending at 2:30 am - to be told, " No hotel rooms anywhere in Dallas". No way for me to get any rest at DFW at that time of night.

The seats are much too narrow and the arm rests are hard and awkwardly high, resulting in shoulder cramps. I am an average sized person ( definitely not overweight). The seats are a similar size to car seats with the added discomfort of incorporating hard plastic arm rests, that force average height individuals (I'm 5 ft 7 (f)) to hold their arms uncomfortably for several hours. The seats are much too close to the ones in front and behind making it extremely difficult to allow fellow passengers to get out, especially when the seat in front is declined. The leg room also necessitates knees banging into passengers backs for the entire flight. This used to be a quality airline who now offer mediocre service for premium cost, coupled with charging exorbitant prices for basic needs, like a seat, or luggage. Blatant and unabashed gouging of clients.

Another 35 min delay landing No apology no communication or acknowledgment about this

Try to humanize onboarding and take AI out. It's embarrassing and useless

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

Changing the flight with app and customer service was very difficult and poor .although I h ad a ticket and seat number still had to pay more money as ticket not transfered. Couldn’t buy another ticket for my daughter on my booking too. Customer services’s appealing. My daughter was ill and noine cared.

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.

The seats were comfortable and dinner was good.? I ended up with food poisoning, not their fault. I caught it somewhere in Barcelona. I didn't tell the flight attendant so it was up to me. It is a good airline. I was just ready to be home

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.

Taking off and landing were smooth. I didn't have anything to complain about.

The sad case is that BA is often late. I missed my connection outbound and then was rebooked in another biz class seat some 10 hours later. I opted to change to economy (no compensation refunded of course) that was only 5 hours later. On the return journey, once again changing planes was very challenging. This time we landed only a little bit late, but deplaning took a long time so the connection was very much in doubt. Some serious running and sweat later, I managed to make the connection but my luggage did not. No messages about the missing luggage, so I had to wait until the entire bag return process was over before seeking out an agent. There was only one and well over 50 passengers waiting to speaking with her. She was quite pleasant, but it took 1 hour and 45 minutes from touchdown to leaving the airport.

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

BA charged me 70 euros for one bag on my return after having recognized my frequent flier status and charging me nothing for the same bag on the outbound. Their employees are not well trained and rules are inconsistently applied.

I couldn’t select my seat until I checked in at the airport. Extremely difficult to talk to a customer service representative. Also, the gate announcement doesn’t appear until less than an hour before boarding.

They over sold the flight and I was not able to board. Had to buy two tickets so I would not miss my connection.

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