I could clearly see the difference of Air France from Atlanta to Paris and then from Paris to Bengaluru. To Bangalore the WiFi was not free and even the flight seemed an old one, I am just curious why.

I could clearly see the difference of Air France from Atlanta to Paris and then from Paris to Bengaluru. To Bangalore the WiFi was not free and even the flight seemed an old one, I am just curious why.

It was my first KLM flight and I loved it. Thank you very much.

Flight was on time, staff are friendly and helpful onboard.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

The baggage service at Malpensa was the worst ever. We wanted for over an hour without any information, they broke my suitcase, and the services of the local luggage services company was below any usual services level of a KLM partner.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

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

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

Flight from Fort Wayne to Atlanta was the smallest in terms of cabin space that I've ever seen. A carry on I've used for 20 years BARELY fit in overhead compartment. I'm 5'10" and felt very cramped. Not the best experience.

I was happy that I was able to get a last minute flight but unfortunately my seat was a middle seat. Even with Delta Comfort I wasn't comfortable

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

I think they can provide the better food/snack option for the 4 hours flight. Drinks are fine.

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

Don't need the male flight attended lecturing. The whole plane on how to act when there was no problems.Other than that everything was great

Why, on an 11+ hour flight, is the food being served at a speed resembling a 90-minute flight? Flight crew practically threw our food at us, then cleaned it up before everyone was done. All, presumably, so that they could retreat away for the next 7 hours to be completely unavailable. No additional beverages were served for hours. Delta is supposed to be the premium American carrier, but on this flight, it made me wish I was flying someone else. Also, the “upgrade” to comfort+ is a joke. It was worse than Japan Airline’s lowest level economy class. Literally no comparison between these two airlines. I wouldn’t fly Delta from Tokyo again unless I absolutely had to. Very disappointing amenities and service!

It was a very smooth ride. Not sure on a flight departing at midnight can be much better but it was late arriving and I had an early day so really just the logistics.

Dovevo prendere il volo da Atlanta a Buenos Aires alle 22 invece è stato sospeso senza nessun preavviso e rimandato al giorno dopo alle 9 del mattino, i parenti che mi attendevano all'aeroporto sono dovuti andare in albergo e non ho avuto nessun risarcimento danni. Ho mangiato al bar dell'aeroporto un piatto di d'insalata con 4 anelli di calamari col voucher di 30 dollari perché la cucina dell'albergo era chiusa ed ho dovuto pagarmi la bibita, 8 dollari per una birra, e anche la colazione del giorno dopo non compresa, deplorabile.

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

They lost my baggage and I still have not got it back. Disgrace

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

A couple of minor delays in boarding but very professional and efficient staff.

Sky priority means you get to use the KLM business Lounge.

The crew was great and handled our unexpected detour with proactive communication.

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

Good Poor. service onboard No food. Low quality for economy plus

There's not enough leg room in economy class. The seats are very narrow as well.

8+ hour flight with no tvs working and no usb port working to charge ones own devices was brutal (traveled with 2 small kids)… yikes

When I bought the ticket, right away I got a problem, I had to cancel. Unfortunately never ever I will use kayak or Iberia again. When trying to cancel kayak told me to talk directly with the airline, the airline talked to me through whatsap and told me to deal through kayak. Both of u never took responsibility in helping me out. You kayak did not want to deal with me. I called my credit card and now we r disputing the charge bc u have a pathetic customer service.

Very poor experience the flights were delayed and poor. I think we should have been upgraded on the next flight. I don't think we will be flying again you coming or going in the states and out of the country. This was a nightmare I realize that the flight wasn't so expensive but I still think we should be given at least a third back for the cost of this experience

Flight was delayed by well over an hour. Communication was terrible.

How to get an aisle seat without paying extra? The young lady next to me was assigned the seat.

Tampa to Charlotte - very upset that the orig flight from Tampa to Charlotte was delayed because they couldn’t refuel properly so we missed our connection. Not at all happy about how American handled it. Very inadequate amount for meals ($12 per person for a meal???) and the guy (Kelvin) acted as though he was doing us a favor providing extra vouchers for breakfast when, in reality, he simply duplicated the dinner ones so we would be on our way - very dishonest and poor customer service. (By the way, his gum chewing and body language was very rude) We arrived our final destination more than 24 hours later. Very bad business. Charlotte to Madrid - although the flight we finally got on was 24 hours later than scheduled, the actual flight was comfortable and pleasant. The movie choices could have been better. Madrid to Sevilla - The food was good but basically thrown at you with a don’t bother me attitude. The plane itself was quite dirty!

The boarding process was horrible. As a business class passenger I had to stay the long line after the gate doors because the was no special priority boarding. After the full of people bus stop near the plain nobody from the stuff was organize passengers on the ground before the plane. All passengers from economy class were using the first ramp and passing business class to rich their seats in economy class. But at the same time the second ramp to economy class seats was absolutely free. Bed selection of vine. At the beginning of dinner Cava was finished. The food was very simple for business class and not tasty. It is impossible to serve grilled beef in bouillon instead of creamy souse. Instead of espresso I got filtered coffee from the pot. Second meal during 12,5 hours flight as a small piece of tortilla is too small.

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

With three empty seats across the aisle from me I politely asked the crew if I could sit in one of those seats. They initially told me I couldn't do it for my safety. When I pressed them again they blamed the captain. So which was it? I didn't appreciate either nonsense explanation simply because they didn't want to honor my request.

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

Staff member at boarding gate was rude, and more than once!

The issue wasn’t necessarily with British Airlines but was a reaction to their delayed flight from Miami to London on Aug 18. Due to the delay out of Miami, we missed our BA flight with Aer Linguis on the 19th from London to Cork, Ireland. The attendant in London was helpful and rebooked us for a flight later that same day ($120). However, she failed to mention that as a result of the missed flight, our returning flight was also cancelled and the rebooking cost was $451. Disappointed at the lack of communication between airlines and between the agent and the customer.

Lost bag on an hour and a half flight with no connections - ridiculous!

You lost my luggage on the trip to Dublin and again on the way back, still waiting on luggage.
