Airline reviews

Pros: "The crew is excellent but the seats are not comfortable enough. There should be a way to balance money and comfort,not just placing people in seats they do not fit into"
Cons: "Nothing,just the seats. Cleanliness was perfect"

Cons: "It's KLM. What else do you need to know."

Cons: "The only complaint I had was that it was very warm on the flight (and I usually get cold on flights), and in the seats we had there weren't fans above the seats. A few rows up they had fans, so apparently you have to pay extra for air... This wouldn't be a big deal on a short domestic flight, but for an international flight it was a long time to be uncomfortable!"

Pros: "Fast boarding"
Cons: "Slow in refuelling, got us delayed for 40-"

Pros: "Everything works and quick to get to destination."

Pros: "Flight arrived on time"
Cons: "No food provided "due to a strike the previous day". Not sure why this would impact on providing a sandwich or snack particularly when champagne was still available for first class passengers."

Pros: "Service and crew amazing friendly and went out of the way to Make u feel special even the pilots gave updates thru out the flight"
Cons: "Not being to help on the ground in Copenhagen with delta issues"

Cons: "I was seated next to the restroom, which is not a pleasant experience for an international flight."

Cons: "I congratulate the KLM crew!"

Cons: "Fix the damn KIOSKS at Vienna!"

Pros: "Great crew, comfortable seating with enough leg room."
Cons: "Provide dinner before getting to joburg, instead of a snack. Flight arrives late so dinner would be appreciated"

Cons: "This return flight was much better than the flight going to Amsterdam. I believe the biggest factor was the type of aircraft. The old 747 just didn't meet expectations. The newer 777 on the way back was much more comfortable, with better amenities."

Pros: "Food, entertainment and crew was exceptionally friendly."
Cons: "Seats not great for such a long flight."

Pros: "My seat"
Cons: "My suitcase wasn’t in the plane. 8 hours in the plane and no one offered us water. We had to look for flight attendant. Entertainment wasn’t great not too many choices and quality of screens was poor"

Pros: "Nice aircraft"
Cons: "Unexpected refueling stop. 2 hr delay Lost connection Reached destination after 18 hr delay"

Cons: "The check in desk was late opening & the carry on luggage size was smaller than advertised on their website, so it had to be put in the hold. Open on time to prevent less stress to travelers & give more accurate information about cabin luggage."

Cons: "Lost all our bags so couldn’t ski"

Pros: "The flight arrived a few minutes early."
Cons: "The plane was extremely old and in poor repair. The seats were extremely close together. The inflight entertainment system, wifi and passenger electric outlets were all non-functional. Even the wastebin in the lavatory was full and an extra bag was put on the floor."

Pros: "Nice crew pilot food and beverage"
Cons: "No wifi"

Pros: "Crew was awesome"
Cons: "."

Pros: "Restrooms clean, decent food and drink, nice cabin crew."
Cons: "No complaints"

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: "Everything was great! Crew incredible. They acknowledged my wife’s birthday and made her feel special. Food was ultra salubrious. Loved the big screen monitor."
Cons: "No complaints about anything."

Pros: "We were fed a nice pasta meal and offered drinks twice. They also gave a muffin for desert. The flight attendants were very nice and attentive with cheerful smiles. I wish every airline had service this good!"

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

Pros: "Sound was broken on my TV set!"
Cons: "Called stewardess twice to assist. No response!"

Cons: "Our two hour connection in Paris became 30 minutes because Air France was late in leaving Washington. So our luggage didn't make to to KLM to Amsterdam. My poor rating was because the luggage handling was really poor. Lots of flights from Paris to Amsterdam (almost hourly), but my bag showed up 12 hours later. My wife's bag took 36 hours. And yes, we checked in together. There were lots of confusing messages"

Pros: "We are guessing they either overbooked or they didn't have sufficient passengers on a Tuesday afternoon who's final stop was Glasgow. They rebooked him for 1200 the next day. DFW to MN, St Paul to Schipole, Amsterdam to final destination, Glasgow. So he ends up having to pay for another Lyft back to our apartment in Dallas, then another additional one for the 12 noon flight the next morning. If he didn't have family living in Dallas, he would've incurred a hotel fee too."
Cons: "He was bumped to the next day due to his flight being cancelled. Then re-booked the next day, with an additional layover. Then due to a 32 minute layover that left 3 minutes sooner..."

Pros: "Cabin crew were very professional."
Cons: "Aircraft returned to gate due to fault and was delayed for 45 min."

Pros: "Boarding was a breeze and the staff were lovely. Online check was very simple and easy to navigate."
Cons: "The amount of extras you have to click no to while checking in online."

Pros: "The food and the punctuality"
Cons: "The technology in interteiment is not touch screen"

Cons: "It was announced I can choose between fish and chicken meal but when I requested for fish meal, I was told it’s finished. My seat was 21, and it surprised me. If something can be changed about that then your services would be much appreciated. Thank you."

Pros: "Thankful for coffee being served without charge. Not all airlines do that."

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."
Cons: "The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!"

Pros: "staff was fine"
Cons: "old old plane, very uncomfortable. Tiny bad screen made movies pointless"

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

Pros: "Airline staff good and professional"
Cons: "Nothing one can do, for a 6.2" guy, the metal bar that forms the shape for the pouch for magazines and such digs into knees, ESP if person in front adjusts seat back. Fold out table barely accommodates laptop."

Pros: "Of the multiple international airlines I recently flew with, I would have to say KLM was by far the best. Relaxing atmosphere, comfortable seating, great in-flight entertainment, although I have the go-go in-flight data/entertainment plan with t-mobile (highly recommended), the flight included a decent selection of movies, television programs, etc. The food far exceeded typical "airline quality," even for an international flight - and included a fabulous little snack box with locally sourced gourmet and specialty items such as chocolate from Belgium, fine cheeses from France, and crackers from England. Drinks = gratis, and crew was exceptionally attentive and went out of their way to make flight as pleasant as possible."
Cons: "Nothing."

Pros: "The crew were pleasant"

Pros: "The flight was delayed due to fog, but the staff was amazingly helpful to make sure everyone got to their destination."

Pros: "Nothing"
Cons: "Flight from Amsterdam was 2 hours late. Caused me to miss connection on train from London to Leeds which then cost me 124 pounds to rebook. No information was forthcoming at all at the airport and there were 3 different departure times given. Absolute chaos. The airline is a joke"

Pros: "The crew were just amazing, such lovely male stewards! They were helpful and friendly and generally wonderful."
Cons: "The entertainment was quite dated and didn't have new movies etc"

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

Pros: "Efficiency and speed of boarding was acceptable. I have no complaints about that aspect. The Comfort+ seats were worth the upgrade, pretty comfortable and reasonable legroom unless you have a big carry on stowed under the seat in front of you."
Cons: "The first announcement they made to all of us in the economy section was thay they did not have any headphones for anyone but business class. I was told when I booked the seat that the headphones would be complementary. So I did not bother to bring any assuming they were going to keep their word; I figure I'd make it work and watch a movie without sound. If that isn't bad enough midway through my nine hour flight my monitor went out and would not turn back on."

Pros: "Professional, friendly service. Punctual, safe flight. Comfortable, spotless airplane."
Cons: "What is there not to like about KLM? I cannot find anything."

Pros: "Atmosphere, crew were very professional and friendly"
Cons: "Seats were a little too narrow, and quite uncomfortable when a broad shouldered person is sitting next to you"

Pros: "Same as above"

Pros: "It was a short flight so it was O.K."
Cons: "Boarding was odd. Go to airport early and counters were not open, did on line check in so was able to avoid the self check in at airport. Also self check in luggage seems confusing with no ground crew to help. It didn't affect me but lots of confused passenger."

Pros: "Seat space was good for a short flight, inclusive of free snack and drink."
Cons: "Too much overoverhead luggage."

Pros: "The crew was really good, made sure our needs were met."
Cons: "The seats were quite crammed."

Pros: "Video screen was in the head rest of the seat in front of me. Power outlets at the seat."
Cons: "More room and wider seats"

Pros: "Crew"
Cons: "The stretched 757 is a crowded cramped uncomfortable airplane."

Pros: "Efficient"
Cons: "Free wifi"

Pros: "One attendant did it all. And very well. Impressive."
Cons: "More snack options."

Cons: "Long delay."

Pros: "Appreciated how timely both United & Lufthansa flights were."
Cons: "1-Isles are so small it is difficult to navigate a small carry-on through them. Seats seem smaller and closer. 2-Not able to select seat until the day of departure and having to pay an extra $149 to get an isle seat with United, while not given a possibility to upgrade with Lufthansa which placed me at the back of the plane in a middle seat between two large individuals."

Pros: "I typically have a way better experience with United than I do with the cheaper airlines (such as Frontier & Spirit.) I like that I can check a bag for free when I book with my mileage credit card and that I can carry on a bag without hidden fees."

Pros: "nothing"
Cons: "everything started when we tryed to check in online for our flights with Lufthansa, when we got some errors saying that our flights does not exist. NO Emails, not calls, no messages, no voice mesagges left by the company! -called the client service, located in Philipine apparently, the lady confirms that all our flights were canceled (3), then she hangs off the phone. -called the second time, another lady is rebooking me on a different flight, but she informs me that my husband is not on the same reservation as me, so basically he is in another flight. Eventualy she is changing his reservation as well and puts him on the same flight as me. -waiting for the confirmation email, of course the reservation is just for me, no husband anywere. -called the third time, a nice canadian gentelman informs us that the second flights was canceled so he will redirect us via NJ instead of Washington. -we are rushing to the Richmond airport to catch the NY flight, at the counter they let us know that this flights was canceled and we are back on the DC flight. -when ready to board in the DC flight they are announcing the this flights is delayed from 1:30 pm to 7:30 pm due to weather conditions. -waiting in the line to be rebooked in another flight, after 3 h of waiting they decide they can fly to DC at 4:45 pm, with about 15 people on board."

Pros: "Getting off the plane"
Cons: "Crew disappeared for most of the flight as if it were a red eye and only served everyone one package of pretzels and came by with the drink cart once...this was on a seven hour flight. they did come by two other times wth a Tray of water but overall were not very friendly whatsoever."

Pros: "Very annoyed with the direct tv. No gluten free option for food/snacking."
Cons: "comfortable seating. nice staff. on time flights."

Pros: "Again, on time and great crew."

Cons: "United Express flies out of Terminal A at Newark (EWR) and routinely they do not have Precheck lanes open. Despite flying on the Saturday after Thanksgiving they only had one mixed security line open. When I asked TSA they said they simply weren't staffed to have a Precheck line open. Everyone was working diligently but this happens every time we fly United out of Newark. Traveling with 2 small children it is incredibly frustrating to have to go through the full security line, take off our shoes, and take all of our electronics out of our bags."

Pros: "I got to my destination and didn’t die."
Cons: "Poorly marked gate. Late boarding time. Sat on shuttle for 20 minutes before they took us to the plane. Then we sat on the plane with the heat blasting and no air available. Flight was delayed due to maintenance."

Pros: "Left and arrived on time. Great flight attendant."
Cons: "Leg room was barely sufficient to open and use my laptop."

Pros: "A FUN HAPPY TIME AS THE CHAPS WHO SAT EITHER SIDE OF ME WERE CHATTY AND HUMOROUS - THEY WERE HAPPY THAT COLUMBUS DAY WAS TO BE CELEBRATED THIS PAST MONDAY AND WHEN I TOLD THEM I WAS TO CELEBRATE CANADIAN THANKSGIVING WITH MY SON AND HIS AMERICAN WIFE AND THEIR 2 CHILDREN - WELL LET'S JUST SAY THE 3 HOURS OF THE FLIGHT FLEW BY. SMILE"

Cons: "Late departure; tiny, smelly plane; cranky flight attendant."

Pros: "That my suitcase was stowed"
Cons: "Waiting 11 hours for the flight"

Pros: "I always like the multiple entertainment options with the seat back screens. The dinner meal was much better than I expect in coach."

Cons: "They could have used the bathroom to stuff a few more people on this flight. Whoops, no, bathroom not clean. Tray broken on seat. Seated in last row and asked to close bathroom door of it opened during takeoff. Seated next to very large passenger who wanted to share my seat. Sat on tarmac for 30 minutes waiting to take off. For this, I paid $650."

Pros: "Not really impressed"

Pros: "No WiFi. The new United system is worthless on most flights."
Cons: "Entertainment and food."

Pros: "Pilot and flight attendant communication"
Cons: "Seats too close. No food available for last 10 rows of plane. Way too long of a flight for there to be limited food availability."

Pros: "Flight attendant noticed my husbands t-shirt from Galveston and talked briefly about it. Smooth flight."
Cons: "Since it was a smaller plane the seating room was tight."

Cons: "Although the flight was scheduled to depart quite early, it was delayed twice. Weather was good, but incoming flight was late. Then there was no cabin attendant-40 minute delay. Few amenities in Terminal A of JFK."

Cons: "The gate agent for United at Newark was very rude and dismissive. Would not answer any of my questions or anyone who attempted after me. His attitude was very poor and seemed to not care about his job. Plane was late arriving in Portland Maine."

Cons: "The flight was fine, but my flight was cancelled on the 29th and the agent who helped rebook my flight was abrupt, then I get to the airport on the 30th and the flight is delayed another 2 hours. Of course it was all "weather" related, so no help from the airlines. I'm not a satisfied customer. I would have flown Delta if it was possible."

Pros: "On time...."
Cons: "Bigger plane than usual.."

Cons: "Not enough leg room or seat size. Just uncomfortable."

Pros: "Our connecting flight was more comfortable than flight from San Francisco"
Cons: "Delay because of change of plane and 3 gate changes"

Cons: "The pilot speeding up and then putting on the brakes time after time on flight from Norfolk 10:30 am to Dulles today. Very rough flight and it was beautiful smooth air today. I'm a private pilot and could not figure out what was going on,"

Cons: "Long wait on the plane on the tarmac."

Pros: "Flight attendant very friendly and helpful Seat row layout of 1 and 2 On time Legroom adequate Smooth flight"
Cons: "Cabin temperature became too cold Seats small Engine noise drowned out announcements of pilot and flight attendant Narrow uneven disembarking ramp at Portland Jetport Lack of clarity about flight gate in Newark. I checked in at Terminal C and had to take a shuttle bus to Terminal A"

Pros: "On time quick flight."
Cons: "No legroom, snack a joke, no entertainment."

Pros: "Flight staff was wonderful."
Cons: "Newark Airport. The terminal was probably 60 degrees. Navigation signs were the least helpful of any airport I've flown out of or into."

Pros: "Finally arriving at the destination."
Cons: "We were stranded in Newark with little to no air conditioning in 90 degree heat. Our flight was delayed 9 HOURS. I lost an entire day of my family's vacation because of United Airlines and their massive blunder. They said it was because there was no air conditioning, but at the same time they said their crew clocked out and we had to wait for new personnel to man the plane. I find it hard to believe that this couldn't be foreseen and avoided. By the time we finally got our crew, we then had to await for a storm to pass, and then 40 other planes had to take off first. All United offered in apology were $10 vouchers that expire in two days, and a free drink on the plane."

Pros: "Crew member was excellent."
Cons: "As the ground staff had trouble loading the luggage in to the booty...plane was stranded on the runway without AC... caused unnecessary delay. We missed the connection."

Pros: "On time and friendly to Portland as always."

Pros: "Normal things"
Cons: "Making us wait for 3 hours to take off. Did not offer anything in denver."

Cons: "We got on board, waited 20 minutes. Capt said it was a bad reverser, and we were waiting on paperwork for 15 minutes. Long story short, they make us leave the plane after 2.5 hours. Then we wait in the airport for another 2.5 hours. I missed my connection and spent 10 hours in Chicago."

Cons: "Please read above--I was standing at the gate waiting to board when the gate rep told me and another passenger there was only one seat left--on a flight I was confirmed on! The other passenger said he had a family obligation and the rep handed him the last ticket before I could get a word out. I felt so disrespected and like my business and money meant nothing to United. Then began my saga to get to Portland. Unbelievable."

Cons: "Upon arrival the flight attendant left me stranded on the tarmack without a wheelchair for 20 minutes. I have serious balance issues and was terrified. My connection was very tight and I barely made my plane to Portland. The pilot finally saw the problem and got the assistance I needed. This was the most frightening wheelchair experience I have even had."

Pros: "I wish I would have caught her name but the staff member at the boarding gate was fabulous! She is someone I would want representing my company."
Cons: "The wafer served with the beverage & my seat assignment stunk."

Pros: "I had no complications before/during this flight. It was as if the air travel angels were smiling down on me, making little decisions like, "Sure. Give her that rare luxury of having no one sitting beside her... twice in a row. And toss in not one, but two of those United Airlines cookies." (Those cookies are sooooo good.) Really, at the moment, I can think of nothing anyone could've done any better."
Cons: "N/A"

Pros: "There were empty seats and the very polite flight attendant offered for me to move without me having to ask."
Cons: "I arrived at my final destination and walked to baggage claim. I was just standing there waiting when a young girl walked by me in a uniform and said rudely and almost annoyed, "do you have a question". I replied that I was waiting on my bag. She then said these are it and I said so my bag has been lost? Without any empathy AT ALL she again, rudely and now most definitely annoyed said Do you have your bag tag? I said yes and she proceeded to walk away to a corner office. I assumed I was to follow. She took my tag, no communication at all from her, I said what are you doing and she replied I have to file a claim. She then proceeded to tell me that Newark Airport was horrible and never travel through there if I know what's good for me. This was extremely unprofessional. I was simply wanting some guidance from her on what to expect etc. I had to ask her what my next steps were. She handed me a flyer and said if I had any questions to call baggage information listed on the pamphlet. I left. The next day at about 1 p.m. I called the number and the update said my bag had left the airport and was out for delivery. Keep in mind that I had to work the next day after the airline losing my bag and had to purchase shower items etc due to them being in my lost bag. Portland jetport and my home address is less than 40 minutes apart, yet my bag did not arrive at my home until 8:30 p.m. and I'm also not confident it would have ever arrived because I called around 7 p.m. and spoke with someone who called the delivery service to ask their ETA. I paid $25 to check my bag and yet it was lost. What did I pay for?! If I can help it, I will NEVER fly United again and I'll be certain to tell everyone I know about my experience with this airline."

Cons: "Deverted to Newark to get to portland"

Pros: "Very polite, upbeat crew"
Cons: "Newark airport a mess!"

Cons: "I asked a staff member a question about my checked luggage and I felt like he blew me off. No big deal though."

Cons: "This flight was cancelled and the later flights to Portland were all full, so I was offered a flight to Boston instead, with no refund for the bus ticket from Boston to Portland, and of course my bag did not arrive with me."

Pros: "Not much to say about an hour flight. Coffee could not be served due to weather conditions, not airlines fault."
