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.

Flight was an Iberia Flight on Level but seemed to be outsourced to a 3rd airline - Wamos. Seating pattern was different than when booked, we waited on the JETBRIDGE for 45 minutes to board, food was terrible. Movie options were limited to about 20 and very old, TV shows was limited to about 15 and equally as old. Staff was fine but definitely the "b-team". Landed about 60 minutes early and waited on the runway for 45 minutes - despite that Logan Airport in Boston recently added new gates. Mediocre experience at best.

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.

Only two check in counters for online bag drop, economy and premium economy clients, NO management supervision whatsoever, no announcements, whilst Business and first class had three check in counters operational, with the bulk of clients flying economy on a 747…..very poor service indeed. Stood in a queue for two hours to check in!!!!!! The flight crew were equally indifferent.

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.

On the flight from Venice to London even it’s short, 2 hours 20 minutes and mostly people are on vacation, it’s ridiculous to change money for the cup of tea or coffee. Also it’s to much to charge 80$ for 1 piece of luggage

Flying economy is like being packed into a sardine can.

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.
