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

Cons: "Too much light in the cabin because of too many screens on. Should have a separate part of the cabin with screens off allowing one to sleep more easily."

Cons: "I ordered Wheel chair for my parents but one of them didn't get it at all. When my parents were checking in for flight they asked the representative about meal selection and she didn't answer their questions properly and because of that my mom didn't get proper Hindu Vegetarian food on flight instead she got Egg omelet which she couldn't eat. She has to eat just fruits. My mother is a diabetic patient and she needs a food every after some time. I never had such a bad experience before with any other airlines."

Pros: "MCR airport Mert & Greet parking was smooth and efficient."
Cons: "Flight was delayed 2 hours due to bad weather. Additional baggage payment to Air Baltic did not show up on the KLM system and we had to pay again. Nowhere to address this with Air Baltic even in Tallin. Handlers seem uninterested and refer us to ‘the website to address the issue.....’"

Pros: "Very friendly onboard personnel - I really had kind of homy feeling."

Cons: "Very slow service at checkin, was not even available when I arrived at the airport"

Pros: "Comfortable and well laid out seat area"
Cons: "Food was a little substandard for business class"

Cons: "That it didn’t happen."

Cons: "Flight was cancelled."

Cons: "Cramped seating."

Pros: "Everything is top notch for an airline company."
Cons: "Nothing.... I enjoyed every moment of the flight."

Cons: "We did not get two of baggage at the destination."

Pros: "Nothing"

Pros: "The staff the facilities the food all ******. Will definetly look forward to choose both delta and KLM"

Pros: "Flight crew; legroom even in cheap seats."
Cons: "Exceptionally unhelpful customer service when asking about extra kilos/bags. Just quoted the online info back at us. We simply wanted to know how much would be charged if the bag was 1-2kgs overweight. We could not get a straight answer, just quoted the unclear company policy. Extremely frustrating and annoying. KLM offer a superior flight experience - it is a shame their terrestrial customer servic does not match it!"

Pros: "The flight attendants could not do enough for you."
Cons: "Business class was pretty empty but again I was not allowed to change my seat selection online. Pathetic check-in."

Pros: "Service provided by the staff"
Cons: "The navigation of the entertainment system is not very friendly"

Pros: "The supplied pack of toothpaste/toothbrush"

Cons: "Without any explanation the plane I was due to go to Istanbul on at 11.30 was not available. I had to wait for a small plane coming from Edinburgh then wait for it to be emptied of passengers and cleaned. This meant we were over 2 hours late into Istanbul. No explanation or apology. I then missed my next flight in Istanbul and had to purchase another ticket. I cannot believe that air passengers are treated in this way!!! I will follow this up with KLM when I go home from my holiday."

Pros: "I really like the spaciousness, the plug ins and general service"
Cons: "I have a dairy allergy but had no option to prepurchase a dairy free meal. It made for a very unenjoyable flight as I couldn't eat anything they had. What was worse was after I told them of my situation they said they understood and had a meal that would do but there was cheese, yogurt, milk chocolate, etc."

Pros: "Everything - Checkin, crew, food, entertainment"
Cons: "Nothing"

Pros: "No chargers or tv on planes"
Cons: "At Amsterdam we were told that our checkin luggage wouldn't be at Sydney!! Some low fat meals were terrible!"

Pros: "I was upgraded to Buisness so, no complaints"
Cons: "No Marlboro light cigarettes on the duty free shopping cart"

Pros: "The staff was fast and curteous."
Cons: "There is not anything to complain about besides the usual discomfort of travel."

Pros: "Fortunately, the plane was not full, so people could spread out a bit to create extra room. The food was really good! (surprisingly)."
Cons: "KLM's new configuration for this type of plane made the seats even narrower than before. While leg room was reasonable, the 3 abreast seating meant a lot of discomfort, especially in the row right in front of the restroom."

Pros: "Comfortable flight to Amsterdam for vacation in UK. More meals than expected. Also wasn't expecting some of the comforts offered to "regular" class seats like eye masks, ear plugs, pillows and blankets. It was an overnight flight, so maybe that should have been expected, but I don't think we had those 4 years ago when traveling overseas."
Cons: "Nothing. This is filler text to meet min characters."

Pros: "Flight attendants tried their best given what they had to work with."
Cons: "They can not retire these old Boeing 747's soon enough. Due to mechanical problems, our flight arrived at LAXfour and a half hours late and further problems with the cargo door caused an additional one hour delay of our take off."

Pros: "It's the best flight I could get for such a low price. But don't expect to to get the best and newest planes around but it's still overall a good experience."
Cons: "Quite bummed that the flight didn't have wifi / USB):"

Pros: "Crew was excellent"
Cons: "Economy was very tight! Seats were uncomfortable"

Pros: "Excellent service and comfortable flight"
Cons: "Flight delay roughly an hour"

Pros: "Much more civilised for the same cost (or less) as the budget carriers. Proper food and drinks included as is the norm with international flights even though it's a very short haul."
Cons: "The stinky guy behind me, but that's not the airline's fault."

Pros: "There's almost no padding to them and they're very narrow. I know it's nothing new but I'll keep complaining until something changes, if ever."
Cons: "The crew was wonderful, the food was extremely good for economy cabin standards."

Pros: "The price was nice."
Cons: "Plane looked unkept on exterior. Crew was nice but lazy."

Cons: "My family of five spent a lovely week in Sardinia. Our return flight took us through Rome. We were boarded an hour ahead of departure from Rome for our 10+ hour flight, only to be held on the ground for a one hour delay. Barring equipment malfunction, this is a totally unacceptable way to treat people. Be assured that I will avoid Rome in the future if at all possible. I trust that Rome nor Italy need my tourist dollars and there are many lovely other places to spend them. Exceedingly disappointed, Pam Just"

Cons: "Me quede un dia completo en Panama en el aeropuerto."

Cons: "Luggage lost and not found. Contact to executing airline KLM very difficult, because the case-nr. on the "lost-luggage-form" was unreadable. but without this number, you can do nothing, because it almost impossible to get someone on the phone at KLM. Mostly you talk to computers. Obviously the phone is oldfashioned and you need twitter and facebook. Poor service, KLM So you can have a pleasant flight, but if you need service, you are lost."

Cons: "Boarding was just a mess - lines and delay Crew is apathetic There is no amenity kit for passengers Food could be better"

Pros: "Friendly stuff"

Pros: "The crew was efficient and friendly. The plane took off on time and landed on time."
Cons: "Boarding was slow and tedious. People still crowd around the boarding area despite there being row for the zones. Why they don't board from back to front is beyond me. The food was mediocre at best."

Pros: "Plane was new, and seatback screen responsive and functional."
Cons: "Economy seats not very comfortable, very tightly packed together"

Pros: "Fantastic Crew!"
Cons: "Seats are comfortable but tight."

Pros: "Very efficient boarding. We actually departed earlier and then landed in Barcelona 15 minutes ahead of schedule. Overall a very smooth experience."

Pros: "1. The flight attendant staff was very polite and cheerful. 2. The plane was clean and comfortable."
Cons: "1.The entertainment monitor did not function well enough to be able to watch. 2.The headset only function on one ear. 3. You could not hear announcements over the PA system"

Cons: "Departure delayed, reschedules and then cancelled without any direct notification to us with 2 first class tickets !! If we didn’t have Kayak we would be sitting in the airport !,,"

Pros: "Not much but the staff"
Cons: "No room, boarding was slow, zero bag or legroom"

Pros: "En deux mots, tout était médiocre, avion, « nourriture » (si on appeler ça comme ça) même les hôtesses travaillaient avec une sale gueule.. Très déçu d’Air France"

Cons: "Leg space."

Cons: "Staff where so unhelpful that I missed my flight and then refused to offer any assistance as to how I could remedy this situation. This cost me over €180 which is a weeks food and stay for me. Don't fly with these guys or with air Croatia."

Pros: "The free glass of red wine when the plane finally took off."
Cons: "The flight was delayed. We were told that it was just a half an hour delay by the man that was informing us of the delay and then we were then told by a woman that it was going to be over an hour. We weren’t told any specifics of why the plane was delayed, other than: “ the engineers are looking at the issue now”. We received messages saying that the flight was cancelled but then we were told to ignore that. We were told that we would have an update every 10-15 minutes but by the time we had the next update was 1 hours later, we were told that the plane will depart at 15:50- which we did. But we also sat on the plane for an extra 2 hours or maybe even more (couldn’t bare watching the time at this point) because the man that was supposed to push the plane backwards in order to reverse the plane didn’t turn up so we then had to wait for all of the other planes to take off before we could. Eventually the plane set off at 18:20 and I got in France 19:30-20:00 ish?"

Pros: "The airplane was modern, and the crew very good. Nice, service oriented and in general trying to make the flight experience as good as possible."
Cons: "The flight was very late. I lost my connection. My bag was lost and unable to recover it so far (after more than 24 hours). About to initiate the next leg of the trip with no clothes or any idea if my luggage will be recovered."

Pros: "The cabin crew were excellent"
Cons: "We were transported to the plane which was quite some distance to the plane via bus after climbing down steep stairs from the departure gate area. Then we had to climb steep steps in extremely hot weather. We were then delayed for a hour in the plane in very hot conditions as the plane had its air conditioning off and the ground air conditioning was not put on. We were swearing in the heat for an hour!! We arrived at our destination and hour and half late!!"

Pros: "Faster"
Cons: "Waited a while before take off."

Pros: "The noise-canceling headset is good."
Cons: "The premium economy seat is not reclined at all. The neighbor's seat is too much flexible. This is a maintenance problem. We report these problems to the crew, though there ignored... I should have chosen an economy class seat."

Pros: "Charmingly nice crew and involving captain"
Cons: "the delay of the flight, the drinks we had to pay in the lounge, some poeple got a 25$ compensation coupon and we didn’t. The connecting time was about 1 hour and the luggage was not put on the plane to beirut"

Pros: "Speed, professionalism"
Cons: "Nothing"

Cons: "There should be more layover time as I almost missed my flight and My luggage was delayed!!"

Pros: "nothing"

Pros: "Friendly crew and exit row had nice legroom."

Pros: "Boarding was very efficient"
Cons: "Losing my luggage after checking it at the gate when volunteers were needed."

Pros: "Disorganised and slow"
Cons: "Couldn't organise a booze up in brewery. Baggage offload took forever"

Pros: "I didn't feel cramped in a Window Seat. Two meals were served during the flight. It was nice to get back to being fed something other than skippy snacks on an airline flight."
Cons: "I was ignored over and over again as ice cream, drinks and snacks were offer by the crew. It would have been nice if some would ask me before falling asleep if I wanted to be roused for snacks and desserts. After being on back to back flights of more than 10 hours each it would be considerate for the crew to be aware of my length of travel and to make sure they don't assume my resting my eyes is the same as me being asleep. Even when I was awake it appeared I was being overlooked, ignored and left out of complimentary services I saw other receiving....my bad for not asking to be noticed."

Pros: "quick flight 10 min ahead schedule"

Pros: "movies were great, watched a lot of them food, while nothing to write home about, was at least tasty and not inedible the staff was great, friendly, welcoming, hard working loved that we could have wine and snacks"
Cons: "we had paid for the exit row and had a luxurious amount of room. But when we tried to sleep, our fellow passengers came and stood at our feet and talked so loudly that we could not possibly sleep. They stayed there for more than an hour. Would have loved for the staff to maybe ask them to tone it down, if not move."

Pros: "This plane was the nicest plane I had ever been on. Very comfortable and the entertainment was amazing!"
Cons: "Airplane food is airplane food I guess."

Pros: "Same as above, the crew was very friendly and the food was great."
Cons: "Seating was cramped and uncomfortable for a tall person."

Pros: "Courtesy staff excellent!"
Cons: "Console for gaming poked guy in front. Needed joystick"

Pros: "The air France staff were phenomenal. Very professional and courteous. Almost so courteous you thought it was not genuine (however it was)...by end of the flight they made you want to write a letter on their behalf."
Cons: "Seat didn't recline as much as needed and was no in flight entertainment."

Cons: "takeoff delayed due to "technical issues". similarly landed after an almost 60mins delay!"

Pros: "Departure and arrival were on time. Boarding was orderly."
Cons: "Seats in Premium economy are not comfortable for a long flight, very difficult to adjust."
