Pros: "Impressive service... amazing crew, very friendly and professional"

Pros: "The crew tried to be helpful but were equally frustrated with the ground crew."

Cons: "The seats were uncomfortable"

Pros: "Entertainment options."

Pros: "Everything"
Cons: "Nothing"

Cons: "una valija se perdió. Eso desató el descontrol que tiene KLM para seguir el equipaje. No hay como hacer tracking. No hay un teléfono a donde hablar, la web está desactualizada y con información equivocada. Direccionan a usar canales de twitter y facebook que no responden. Primer experiencia en KLM y no pienso nunca más usar esta aerolínea. Llevar el equipaje o resolver un problema sobre valijas es de lo más básico de una aerolínea y no lo hacen."

Pros: "Crew was courteous and polite! Entertainment system had some great movies at no additional cost."
Cons: "Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?"

Cons: "They didn’t let us board the plane. Allegedly the plane was changed and make us travel by train!! They offered us a compensation but we haven’t heard from them yet. Not good experience at all."

Cons: "Our flight was canceled from Amsterdam to Bordeaux and did not receive any direction and had to find alternate flights for ourselves with the personal expense of using our own cell phones. Then our luggage lost for 3 days. Not happy! We ended up flying from Toronto to Paris then to Bordeaux. Lost my upgrade money for seats. Now have to deal with KLM for refund!"

Cons: "One of the senior stewardesses we're very rude. Whether it's her personal opinion or KLM's policy, it's unreasonable to think that a 3 years old child could or should hold her pipi over 20 minutes, while they slowly and inefficiently trying to give out food. Several parents were there with the request to let us through to the toilet with small children and she smiled in our face and said "no, we will finish first and than you can go". She might be not fit for the job anymore, but KLM can't afford this kind of treatment."

Pros: "The crew were lovely and welcoming. We was given snacks and drinks on the flight which was great. Take off was a bit delayed but boarding was smooth. Couldn't complain about the comfort as was only just over an hours flight."

Pros: "Staff superb. They even surprised us with an exit row and a gift for my partners birthday! Amazing. Samantha and Dennis also took time to come and personally wish him a happy birthday. A lovely touch. This airline runs like clockwork. They are just great. The sandwich and stoop waffle are nice too."
Cons: "There is a bus to the plane, so that takes a bit of extra time but they are very well organized."

Pros: "Price"
Cons: "Klm flight has very congested seating Getting information about eticket was pain"

Pros: "Crew was friendly, and the food was better than the usual KLM fare."
Cons: "The "new" seats were hard and uncomfortable. Avoid any kinds of seats near the bathroom in a configuration with 3 abreast next to the windows. The "aisle" seat is essentially a "waiting area" for the rest room."

Pros: "Short layover connecting from US flight and luggage transferred ok to destination. Food option not great but at least they didn't charge for it unlike some other airlines. No entertainment but to be expected on such a short flight."

Cons: "Flight delayed ... Myself and three other colleagues didn't have our luggage show up from KLM flight from Amsterdam to Brussels...even though all of our luggage was labeled "priority". Once in customer service line, we looked and saw that many of the other passengers on our flight also never received their luggage. We estimated that 20-25% of the people on that flight did not receive their luggage as they were in line with us for the same problem. Hard to understand how so many pieces of luggage could have been overlooked and not loaded on our flight. Obviously there is a huge gap in their quality system to ensure mistakes like this are prevented."

Cons: "Fewer entertainment options than the delta flight. I got excited with that first flight."

Pros: "Good food, good entertainment system, comfortable seating."
Cons: "Only one toilet working in business class. A crew member told me that it was a decision to fly with only one toilet to ensure no delay. There was a disgusting stench of sewerage for the complete flight from Amsterdam to Johannesburg. This was in all likelihood due to the broken toilet on the left side."

Pros: "Price line is better not thief like you yu take my money for nothing my husband not traveling your given me fake tickets . bring my money back on my account. am gonna take to court yu fukin beach.yubstolen my money"

Pros: "The crew were dope"
Cons: "The flight was completely full and uncomfortable"

Pros: "Zip"
Cons: "Everything!"

Pros: "The flight was on time; other than that, nothing was good."
Cons: "Everything! For starters, the seats. It seemed as if we were inside a cage where you can barely move your hand. Extremely disgusting flight!"

Pros: "Staff found us two seats together. Food was good."
Cons: "Email telling us about pre airport arrival check in and seat selection."

Pros: "The crew was kind and smiling (not like the worst crew I’ve ever had Brussels Airlines)"
Cons: "The food"

Pros: "Crew had a good sense of humor"
Cons: "Don’t lose the luggage."

Pros: "Comfort seating in premium Plus"
Cons: "Crew in this section needs to be more customer centric"

Pros: "Crew was working hard and fast and very attentive. Seats were OK."
Cons: "i would have liked a better selection of music, especially classical."

Pros: "Crew was nice, attentive, courteous and professional. We arrived on time, landing was fought (night landing) and all of our luggage arrived with us."
Cons: "Airlines are nickel and dimeing the customers. Everything is being charged and many times you find out the hard way. I will avoid United due to their charging procedures and rigidity in their application of their billing."

Cons: "i ordered a vegetarian meal and didn't get one."

Pros: "Everything was as I expected"
Cons: "Nothing flight got us into Paris early"

Pros: "I thought the process of board was excellent and seats were comfortable."
Cons: "The shuttle driver was confused on what plane to go to and lots of steps."

Cons: "too long time before I was transportet with a wheelchair out to the flight. no food even not a biscuit."

Pros: "The staff was great but we hade one hour delay bording went very slow"
Cons: "My seat could not move and the antertainment system dident work"

Pros: "Sleeping!"
Cons: "Did not actually get a Polaris type cabin layout. The plane had not yet been converted."

Pros: "The flight was short."
Cons: "The last seat didn’t have a window so if felt like you were crammed into a tiny space and had no idea what was happening."

Pros: "Great flight"

Pros: "Comfortable. Good entertainment and good service. Crew was nice"
Cons: "Missed our flight from Brussels to Zurich. United said we were booked on next flight six hours later. Gave us vouchers and that was it. Went to check in and the carrier said sorry you can’t board United did not book you. The voucher just has prior info and this flight time. So we missed getting on that flight 3 total hours on the phone with United and they did nothing but put us on hold. Thank you to Brussels air who finally after many years and frustration helped us so we could leave. More than 10 hours later than we should have. Horrible experience and we lost a day of vacation and pre paid plans for the evening I will never use kayak again for international flights. As that was part of the problem per United (probably BS but won’t ever risk it again) and will never use United airlines again as their customer service and lack of caring showed that companies true colors. I hope the rest of this dream vacation is better than this nightmare was."

Pros: "We were surprised to find ourselves assigned to the bulkhead seats where we had extra legroom and great access to the restrooms."

Cons: "Wish I could have selected my seat when booking my flight"

Pros: "Wonderful uneventful trip!"

Pros: "IAD to Brussels Flight is ok, just stuck between 2 guys with BO. Not really the United Airline's fault. But I hope they can atleast put a sign or something."

Pros: "Nothing"
Cons: "Checking was chaotic with non working terminals and insufficient staff Plane was real old (4” scree...even my phone has bigger screen) Onboard drinks were exorbitantly priced (paid 8.99$ for gin and tonic where I got only half can of tonic) Food was ok"

Cons: "Too cold. Was freezing all the way over."

Pros: "The price, the mango sorbet, short flight into Belgium, the coffee, the water being offered often"
Cons: "The tray was very dirty and obviously had not been disinfected from the previous flight. So I brought it to the attention of one of the crew members, and I felt like she made fun of me in front of other passengers for not liking my tray dirty; and she got a little paper towel for serving, wet it with a bottled water, and wiped my tray quickly. Not hygienic at all and not a word of apology. AIR FRANCE is so much better when it comes to customer service! Also I did not like the constant interruption on the speakers, very loud in my headsets and difficult to watch a movie on tiny screens. The crew members seemed very bossy and uncaring, if not actually rude."

Pros: "Very friendly cabin crew made this trip pleasant and entertaining."
Cons: "Despite plenty of empty seats, the ground personnel would not consider changing our seat assignment at the gate to allow us to sit together."

Pros: "I was put up in a hotel"
Cons: "I never received my luggage. I waited hours and Swissport never filed a report. I did see the Brussels flight I should have gone on did depart late. But as I was waiting for luggage and they gave me a hotel room I hadn’t checked the screen. I was most concerned of the person travelling to pick me up in Bordeaux as it is a journey for them as well"

Pros: "Loved the hindu vegetarian food. Incredibly tasty and I didn't expect it. No delays. All went smoothly."
Cons: "Movie selection was weak."

Pros: "Amazing"
Cons: "Nothing"

Pros: "Very good flight, good service and good night of rest."

Pros: "Chill easy flight no issues"
Cons: "Nothing. Everything was cool"

Cons: "space between seats!"

Pros: "There was a good entertainment system with a lot of new options."
Cons: "My itinerary said I fly on Brussels Airlines on a specific flight number. I went to the international terminal to discover it is not there. I then asked multiple aiport staff members if they heard of Brussels Airlines and they said they did not. One person said it may be terminal 1, so I went there based on very little information and with hopes it would be there. I got to terminal 1 to discover there is no Brussels Airlines. I walked to Lufthansa because my return flight is through them, but it was not there either. At this point I have 45 min to make it through security and board, and no one can tell me where Brussels Airlines is. The good news is the flight was delayed, and I got an email from United Airlines with the flight status. This is the first time I was contacted by United and there was a completly different flight number than the itinerary. United should be more clear on the airline and terminal information for international flights!"

Pros: "no problems on flight. complimentary wine."
Cons: "seats bit tight for international flight. why do I have to pay more for more leg room"

Pros: "Great crew and flight attendants, kept us informed of everything, very helpful and prompt on all questions and requests. Movie selection was impressive. Boarding was efficient and flight even left early. Surprisingly pleasant experience in economy for a long flight."

Pros: "Flight was on time"
Cons: "One extremely tiny bathroom for the whole plain for a 4.5 hours flight. The bathroom line snaked through the plane the entire flight No complementary water or any sort of drink Seats were very uncomfortable I fly a lot and this flight was the worst by far"

Pros: "Not u til lDr momie"

Pros: "1. We booked seats together then when I checked in they had moved my seat and we were no longer sitting together. And then I couldnt get the window seat I had paI'd for :( 2. No boarding announcement and the "gate" was under construction so was a madhouse to board. 3. The crew member put her sweater in my food and pushed the coffee so hard to the person next to me it spilled all over him. To be fair she did apologize for throwing coffee on him. 4. The TV screens were so old you had to push the "touch" screen so your headrest kept moving if the person behind you couldn't decided what to watch... and then hard to watch anything yourself. The food was nasty."
Cons: "See above. I didn't like anything, this might have been the worst flight I've ever had to Brussels. I thought I booked a European carrier, but ugh it was actually United. They only care about business class and first class."

Pros: "not much"
Cons: "Food was awful. earplugs terrible"

Pros: "Nice food, good crew"

Pros: "The wifi and charging sockets was a very good and beneficial idea"
Cons: "The crew was very rude"

Pros: "Just about everything was perfect. lots of leg room in economy plus, seat next to me stayed empty, the meals were very taste. And the crew members were extremely professional. It was just a perfect experience."

Pros: "Good selection of entertainment."

Cons: "See above comments."

Pros: "We had nice flight even so the airplain was full."
Cons: "Not quite.little bit noisy."

Cons: "See above."

Pros: "The plane is very comfortable ."
Cons: "The entertainment - not enough movies on Russuian or Hebrew"
