Pros: "On flight entertainment has improved greatly. There are so many choices to keep you entertained. I forgot how long I was on the plane."
Cons: "Plane food was not good. The crew were not as friendly, almost exhausted. There was one woman who was not sensitive or compassionate to my fellow seat mate. He was an older man who needed extra assistance. From the look of her face she didn't feel like helping him... as simple as helping him pour ice into his cup. Instead I helped my fellow neighbor. She might not feel comfortable helping a senior citizen but don't be so loud or make a face of disgust."

Cons: "entertainment system had terrible touch response flight was delayed by 1.5hrs"

Pros: "Plane was a newer one, clean, and the stewards were nice."
Cons: "New seating was terrible. The seats are so jammed together that my knees were pushed up into the seat in front. How can anyone be comfortable with this kind of seating arrangements?"

Pros: "Quick flight and we flew over Yosemite (where we recently hiked). Also, the free in-flight entertainment is such a nice addition! My wife and I had the seat open next to us, so it was very nice to have extra room in our row!"
Cons: "Nothing"

Pros: "Crew service, attitude was much better compared to most US based airlines. Comfort+ has great perks."
Cons: "Aircraft was old."

Pros: "The crew were super helpful with my toddler and 5year old as I was traveling by myself. Everyone was very friendly and allowed me to board early as well as helped me when my toddler was crying to distract her. Service was fantastic! The plane was new and I really appreciated having entertainment I didn't have to pay extra for."

Pros: "Free drinks"
Cons: "Corn nuts for snack. I'm allergic to corn. I get people want snacks on a flight and you can't make everyone happy. It was ok. I just said no to them."

Pros: "lie flat seats and linens were very comfortable"

Pros: "On time. No problems."
Cons: "Hard to understand what group was being called to board. No systematic lineup, just crowding around."

Pros: "Service is good. Flight on time."
Cons: "Don't like the chicken wrap which is dry and hard."

Pros: "Nothing"
Cons: "Charging money for window and aisle seats a new low"

Cons: "Apparently, using a third party source lost me the ability to choose my seat on both flights. The only book ahead options are ones I need to pay extra money for which feels like a scam. I won't be able to get a seat ahead of time on the way home either which will be an even longer flight (6+ hours) and will likely be stuck in a middle seat yet again. If this is the case with booking through third party sites, I won't do this again."

Pros: "The small scack/meal was excellent. Good service. Smooth flight. In-out-done! Good job Delta!"
Cons: "Can't think of anything negative. A long time standing by on runway waiting for departure."

Pros: "Big plane and fairly comfortable"
Cons: "It's more of a shuttle than a transcontinental. Seats are narrow with little leg room. Like all others you have to pay for everything. Delta terminal is not easy at jfk. Sfo is fine and works well All airlines are the same these days. Flights are uncomfortable and crew just throws out peanuts and water"

Cons: "The person taking tickets asked me to check my bag. I said ok and he instructed me to step aside and taking anything out of it that I might need. I did this and when I came back they had locked the doors."

Pros: "The boarding was quick and the gate agent was efficient"
Cons: "We not only left 45 minutes late, but there was no beverage service on the flight."

Pros: "Professionalism, friendliness, accommodating, helpful."
Cons: "Suggestion: Pregnant mothers especially without a carry on should be able to board or exit with priority. It would also be helpful for the aisle seat priority to be given to expecting mothers as well."

Pros: "We paid for an exit row seat with more leg room"
Cons: "Airplane was freezing and the flight attendant couldn't be bothered to change the temperature or bring us extra blankets. Ridiculous that we had to pay for seats on top of paying over $1000 for the flight. We had to check our bags when we boarded bc flight was so full, but once we boarded we noticed plenty of overhead room"

Pros: "On time. Arrived 30 mins early. New plane."
Cons: "Middle seat. Very crowded, could hardly work on my laptop. Food was not great. Had a turkey roll. Opt to pay for the $10 sandwich at the airport."

Pros: "Like delta have single tv, good coffe, will be better is from centro o South America , a time w connection and will safe"

Pros: "Entire experience and costumer service was excellent"

Cons: "No internet available (2020). For the my previous flight, a month ago, was the same problem."

Pros: "Due to business I travel allot so I deal with allot of airlines. This is by far the best airlines I have used. Excellent crew and airport staff. I don’t think words can express how satisfied I am with this airlines and airport. The nicest people and great service. Clean and modern aircraft. Going to try flying only with KLM from now on."
Cons: "Nothing"

Cons: "Klm is the best, even on a 40min they served small breakfast."

Then had to wait another hour for checked luggage...."

Pros: "The crew is really welcoming"
Cons: "The seats are too narrow and a bit too hard"

Pros: "Crew was fantastic, seats and entertainment was great. Very good food choices."
Cons: "Everything was very good."

Cons: "I bought tickets thrue you for me two months ago Iit went well but on the last few days I also bought ticked for my brother and his wife and it was a disaster night mare for them bound for Montpellier too to attend a wedding the damn suitcase didn’t get to final destination it was at Orlando but got"

Pros: "Friendly staff"
Cons: "Security check at gate; No priority"

Cons: "The flight was cancelled and had to be rerouted on United Airlines."

Cons: "At the check in they made me pay 50€ for my luggage. This is really upsetting because from Houston to Venice they didn't make me pay. Either the website wasn't transparent or the lady at the desk made a mistake. Very upsetting, one luggage should be included."

Pros: "Last year I flew Lufthansa which was my worst experience flying ever. I thought the new standard was so low I would never fly to Europe again. I had heard KLM was good but I felt this was as good as could be expected actually much better. The food was even good."
Cons: "I would have to dream something up."

Pros: "Friendly crew! More legroom, good entertainment and food was great! Smooth landings pretty much on time."

Pros: "The service"
Cons: "The seats"

Pros: "Flight crew very nice"

Pros: "Easy flight; loved the crew and their friendly customer service. Great food, kept everyone hydrated and fed."
Cons: "The movie options, as well as music and TV options were limited. There were no electrical outlets."

Pros: "Seats were comfortable and there was enough room for hand baggage. I slept during the flight so do not have opinion on entertainment."

Cons: "Didn’t happen."

Pros: "The boarding was easy and you didn't have to wait inline for that long"
Cons: "KLM needs to upgrade the entertainment. It was very hard to see the images on the screen. The planes that KLM uses are old and they sure need to be upgraded."

Cons: "Nothing good to say about this flight. The plane was old with no entertainment. The sits where very compact and not comfortable at all. The food was a sweet bread and water. The flight attendants were rushing and will take a while if you needed anything. I felt like I was taking a bus with graffiti all over the place."

Pros: "Need better quality tvs for such a long flight and better movies There were only 4 Bollywood movies and not the latest ones either"

Pros: "Nothing really"
Cons: "Flew KLM 27 years ago and the airlines seem to be stuck in the same era. Food is poor quality... Have you recently checked the Gulf carriers."

Pros: "Good Experience"
Cons: "Nothing much"

Pros: "Friendly staff"
Cons: "Entertainment was dated and poor in function. Our bags were 99 dollars each and we’re both lost and didn’t arrive. I just filed a claim and got rude service saying I should have filed the claim at the airport baggage area but there was not anybody there to do the claim then he agent upstairs said they just spoke to them and they are there and I should have done it there. This was so rude and there is no way to get back into customs area. If we paid 200 for bags I expect them to arrive on time. I’m asking for a refund of the baggage fees."

Cons: "Bag was lost"

Pros: "The cabin crew were pretty good. That's about all that was good."
Cons: "I paid almost $400 for upgraded seats. When I got to the airport-- no seats-- both ways!! i didn't even have regular seat assignments. I had to choose from the last few seats available. The ticket agent, the gate agent and the cabin crew all did nothing to make up for the fact that their system screwed up and stuck me in a cramped coach seat in the back of the plane for 11 hours-- TWICE! Beyond that, KLM must have one of the oldest fleets in the sky. Both ways LAX->AMS->LAX, I was on a 30-35 year old 747 with no wifi, no power and a ten-year-old entertainment system. Never again."

Pros: "The flight was great."

Cons: "Service from airline host Poorly maintained plane Bad food Old entertainment"

Pros: "Crew was very helpful.food"
Cons: "Food was not upto the mark."

Pros: "From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew."

Pros: "Great food"
Cons: "Sears we're toooo small"

Pros: "Great crew service. Among the best ever."

Pros: "The constant supply of food that was offered to you. The crew was nice and always helpful."
Cons: "The process of boarding in Amsterdam was not organized and felt more stressful than it needed to be."

Pros: "The staff and crew"
Cons: "Nothing"

Pros: "Boarding was very efficient."
Cons: "Limited movie selection. Crew seemed stressed. Gave me wrong meal and then swaped for the right one. I asked for Diet Coke and was given white wine. Food quality was not good."

Cons: "Horrible. First, we lost a suitcase. It could happen but for two days they did nothing and only told us stories (so as not to use the word lies). Within a few hours (and thanks to airline assistance) we were able to locate the suitcase. Even then it took them two days to bring it to us, two precious days off our planned vacation (7 days) At the end of the shortened vacation, we got to the chek in, and told that since the ticket I had purchased form them two months earlier was too cheap ... and since the flight was Over booked, they would take me off the plane if all the passengers would arrive. It's unnecessary to describe what I felt until the plane took off. They apologize constantly, but do nothing practical. a bae company. no me nor my freinds/family will go with KLM"

Pros: "The crew was very pleasant and professional. toilets were very clean adequate overhead space"
Cons: "Very uncomfortable seats in Economy Comfort. Legroom and recline were OK but the seats were extremely narrow. No evening meal and breakfast was minimal"

Cons: "They put us in a Transavia plane."

Pros: "Good flight, we got a nice snack despite it being a short flight, the staff was great."

Cons: "Having to pay extra to pick a seat prior to check-in. I didn't, and got a decent seat anyway."

Pros: "It was very comfortable"
Cons: "The crew was great"

Cons: "Our flight from Nairobi to Lusaka was cancelled for some reason and we did not find out until we happened to log into the website to double check our itinerary. They automatically rescheduled the flight only giving us 25 minutes to reach our next flight...impossible. so, after calling, we were re-booked again and forced into a 13 hour layover in Amsterdam. Our original flight plan had 4 hours. so, because we are a family of 7 with a baby, we had to buy a hotel room to rest, costing us a lot of extra money we had not planned to spend. We contacted KLM for help with the cost but were rejected. We also lost 5 bags somewhere between Chicago and Lusaka, but after 2 days, we received them."
