The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

no issues at all... Kudos to the food. This time was really really good

I travel frequently. The flight was late again... KLM should really try and be on time

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

Amazing KLM service and brilliant economy comfort seats. Well worth the extra.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

The seats are too cramped in that plane. If you’re above 1,80m consider alternatives or first class I guess… There were no emergency exits to seat somewhere with more legroom

Seats actually fit a human! Snack options were a bit lame but that’s ok

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!!!

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.

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

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.

Other than a late takeoff (not British Airways fault) and some delays with baggage, it was a terrific flight. The crew in business class was superb and the seat and accommodations clean and modern. Could not have asked for more.

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.

I paid for premium economy but BA oversold the seats and we ended up being downgraded. Not acceptable given how much we paid for the flight. We were also separated to 2 different areas so not only did we not get the service we paid for, we didn’t even get to sit together. I’m not happy at this treatment by BA because of corporate greed.

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

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.

We got to the airport 2 hours before the flight. We waited in a line to check our bags onto the flight for an hour, even despite having checked in online, as there weren't enough self check terminals allocated to Vueling (yet loads of empty BA ones right next to them). There also weren't enough staff, making them stressed and rude. We had to try and rush through security to get to our gate, which they announced as gate 35 at first and then changed it after ten minutes with no announcement to anyone in the airport that it had changed. So we then had to rush to the correct gate to arrive just as boarding started. It was a thoroughly stressful process and one travelling couple almost missed boarding because of it. The flight boarding and the flight itself werre fine, the staff were polite, but I was dehydrated due to the airport and had to buy a bottle of water as they didn't offer free drinks.

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

Bought check in baggage but couldn’t do it at the kiosk, had to line up just to get baggage tag which was a very long queue with only 1 customer service agent handling all vueling flights. Had to wait about 45mins just to get a bag tag and drop baggage.

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Cons: "Everything was great. Very nice and friendly crew, clean plane, great food. Excellent overall"
Pros: "Friendly crew and helpful staff"
Cons: "Missed connection from PEK to XIY due to delayed arrival and early departure. From XIY to PEK, booked and confirmed 11 departure, changed to 12:30 without notification or explaination. Rushed connections at PEK, pretty much ran from the minute left plan to another terminal, through custom, through all the health check points, security check. Just keep the fights on time and keep the original schedules, not arbitrarily change them."
Pros: "Because of our delay, we flew with Air Thai instead of Air China....much better airline"
Pros: "The price"
Cons: "Staff was not helpful and kind of rude unless you spoke their language. Food options were terrible and not very comfortable seat for 13+ hr flight."
Pros: "The food was good. It was nice that they supply wet hot towels before each meal. The seat was comfortable with the price I paid for. The rest room is nice and clean and quite spacious. The L’occitane toiletery bag was nice."
Cons: "It would be nice to supply mouthwash in the rest room. It would be nice to have a foot step at the bottom to open the trash container. The comforter is not washed and smells."
Cons: "Even for business class there is no TV screen on each seat. Just one small TV screen on the ceiling for a few rows to share. It would be much better with TV screen on each seat. I was sitting in the first row business class and the air hostess skipped me and didn’t give me a slipper. She gave me a used slipper at the end only without a packet. This is unprofessional to treat a business class passenger"
Cons: "Seats are narrow, leg room limited, and food is minimal."
Pros: "The seats on business were comfy, the service excellent, the movie selection was fair to poor, the food was also fair to good largely because they served a heavy lunch rather than a light breakfast."
Cons: "The food and movie selection."
Cons: "More TV show choices and more Hollywood movies although I understand it's a Chinese airline not American."

As on the tin a fair price for a fair flight ✈️👌✈️

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

Everything went according to plan. Check in, boarding etc all were very efficient.

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

Flights were on time. The crew was efficient and friendly.

The Ryanair staff was not polite. We all travelled with the same suitcases as we departed from Thessaloniki, however they decided that for some passengers the suitcase was not the rigth one as far as the dimensions are concerned. Furthermore, one air stewardess asked passengers to close themselves the luggage cabinet in order to prove that the lugagge was not properly fitted, which i think is very unkind and unprofessional. We also had to wait outside , some metres away from the plane until last passengers came off....It was generally a dissapointing experience.

Is good airline but their check in process is not simple

Boarding was chaotic, the gate changed 4 times and we took off 1 hour late

Boarding at Arrecife was commended way too early. Far too long for elderly to be kept standing on their feet. Otherwise we’ll done to all staff.

Cons: "allow a carry on bag to be same as international standard in size and weight. Do you expect international tourists to buy carry on bags that fits your specifications for size and weight? Why do not except same size as other international carriers?"
