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

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

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

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 Crew have no idea about the food they're serving the passengers. The Crew MUST be instructed before each flight about the menu that will be served to the passengers, whether the food is vegetarian or non-vegetarian, whether it is Halal, Kosher or not.

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.

Improve food options. Do not charge so much for checked bags. As some who paid 990 EUR fir the round trip international flight it is horrendous to pay another 140 for 1 checked bag.

Boarding process was chaotic and disorganized. The plane needs updating in the interior. Things are broken, worn out, and dated

My luggage never arrived in Miami; still waiting a day later.

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Service and food are good. However, main cabin with the extra cost one pays could be better. I don't see any difference with the rest of the seats in the regular category. The seats are too close to the ones in front. For short flights it is Ok, but for long ones there should be more space.

As with every airline the seats are not built for tall people.

Fast check in, easy to navigate, crew were very good, the plane was delayed due to a previous flight and I found the cleanliness a little lacking but overall it was fine

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

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.

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.

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 crew was accommodating during the flight but spoke very little English and could not help with information on connecting flight."
Cons: "We missed our connecting flight due to a delay and the airline would not let us through because we could have made our second flight...."
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: "Seats are narrow, leg room limited, and food is minimal."
Pros: "The crew was okay. The seating was great on all except for one leg."
Cons: "On one leg, it must have been an older plane, because the business class seats barely reclined."
Pros: "Crew was great and was happy to get gluten free food i could eat"
Cons: "Not lose my bags :("
Pros: "Boarding was a breeze, flight attendant onboard we attentive, choice of food orders at least two (in business class, can’t speak to first or main cabin passengers.) Flew from LA to Tokyo. Coming back from Hong Kong to LA. Fantastic flights, will use them again."
Pros: "The fare was good."
Cons: "More modern equipment. Tv screens. Movies. In flight magazines in English."

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

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

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

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

Is good airline but their check in process is not simple

On time but no water , milk or refreshments of any kind on board. Which is poor, especially with children and elderly on board. Toilets filthy,

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.

The boarding process was fast and easy , but the airport sign was not up on the board, so it was hard to know the correct gate , on the airplane there was NO Snacks and NO water …. Everything needs to be purchase …. It’s not worthy for the price we paid !

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?"
Cons: "My friend faced a problem he was booking the flight through your site by kiwi.com and he coudnt do the check in because he dont have the email and the password so he had to pay 60€, so i hope if the kiwi.com notes this matter."
