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.

Disappointing. Had to pay 70 euros for one checked bag. Transatlantic flight was cramped, not very comfortable

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

We had a seat that would not function. No Wifi or inflight entertainment was available. Food was very poor. Attendants were very accommodating and apologized for the problems.

They offered several meals and snacks, the crew was very friendly and kind. There was a broad selection of movies, shows, and games. I was impressed!

My son and I are 193 cm tall. We had reserved and paid for seats with extra leg room towards the front of the cabin. The day of the flight, we learned that Iberia had changed aircraft. We were assigned regular seats way back in the cabin. When we landed from our first leg we spoke with agents at the gate and we were told that they couldn’t improve our seats because the flight was full.

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

I could change to business before flight and everything was perfect except for entertainment which was none.

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.

The whole flight was coughing and farting all the way. It was impossible to breathe. If people are traveling sick they should either not be allowed to fly or made wear masks

J'ai perdu le billet 🎟 faute de visa j'ai pas eu de remboursement. J voulais prendre un autre Est-ce que yaura une solution

I will never fly vueling. 1h30 delayed, connexion missed with the crew closing the boarding in front of us. 40 people missed the Barcelona-Orly connexion. hours waiting for rebooking and hotel.. inadmissible

Non stop flight from Barcelona to Rome, arriving on time.

3 hr flight from Barcelona to Gran Canaria. Ŵent according to plan No issues with staff oŕ flight. Many people includiñg us could not get luggage self checķ in termìnals to work. Had to wait in check in line.

The communication about the delay could have been better before and during the flight. Also, this online form could have less bugs. It is almost impossible to type in this window.

Boarding was very poor as the flight was initially delayed. We were told the flight would be at 21:40. We were with our 10 month baby who was sleeping. I received an email from Kayak which said the flight was now due to take off at 21:04. When we checked the screens at Gatwick we were told the gate was closed. The lack of communication was extremely poor and we had to run with our baby and there were many other passengers, including elderly people, also running to the gate. When we got to the gate, the staff had no reasons for the poor communication.

They stop online checkin above a certain capacity. We had to go to the airport to check-in at the desk. Or was offered to pay 7eur extra. Rip off.

I didn't get the wheelchair assistance I'd requested and my flight was on the tarmac, which was extremely painful for me. If this airline isn't for me, that's fine. The crew was fantastic and friendly ab

It was a short flight but the seat was very straight. I didn’t need any service, but wifi was not available. In resume, a normal service. Nice, the punctuality. Thanks

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

The flight was delayed for over 1 hour. The boarding process is appalling making you wait for 30 minutes in the passage leading to the outside door without any seats.

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

Well Is extra charge for everything and other companies include that and the price.

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

You booked my 7 year old son to sit on his own without his mum and dad in s separate row between two unfriendly adult strangers. The plane was disgusting and dirty, aisles and everywhere sticky. The lounge waiting area was filthy carpet and had insufficient seats so we had to sit on it to wait for 35 minutes and my 7 year old sone played on this filthy lounge carpet. The outside of the plane appeared clean. The pilot was helpful with the route and what to expect weather etc.

Comfort isn’t a word one uses on economy airlines! Boarding was okay, delayed but okay, the flight was good, quick and time was made up.

The seat leg room seemed much tighter on the way home My cheese toasty wasn’t that hot - didn’t realise till half eaten

Cardiff is a great airport but they pen you in at a gate way too small for passenger numbers. Called to the gate too soon and air conditioning was not in operation despite the heat. Cardiff should do better as a small relatively quiet regional airport.

Good, everything went straight forward and on time, I am satisfied

Perfect timing, perfect departure, lovely crew on the ground and in the air.

Good flight. Take off a little late but make up the time

Everything’s went straight forward, no issues, good service and friendly crew

Left on time and arrived on time both ways, thank you

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Cheap flights as you expect with Ryanair. I would take cheaper flights over entertainment and comfort for short haul travel. Main issue is usually delays at airports. In this case we landed roughly 2hr30 later than planned due to earlier delays with the plane. Not the worst I imagine

We each paid for 10kg checked in luggage. Flying out there were no issues sharing one case (20kg). Not so coming back. Additional £48 charge and unable to provide an explanation of why it was ok on one journey but not the other, or indeed what material difference it makes between 2x10kg cases vs 1x20kg case. Scam, and appalling from Ryanair.

Easy process and good flight experience The food good be better

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.

I truly don't think there was anything that could have been better. How is that for an endorsement?! I'm a firm fan of BA now, with two flights in the past 2 months. Keep up the great work! And thank you!

New airport for me. A little confusing.bunable to use kiosk for boarding pass. Agent checking us in was professional but not very friendly.

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

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.

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.
