Pros: "Seats are roomy"

Pros: "First leg was on United (codeshare) 767. The seat pitch on that version was good, even for a tsix-footer. The flight was almost empty, so there was plenty of room to stretch across seats and sleep. In order to avoid dairy, I order kosher meals - and the quality was OK. The cabin crew was nice to start with, and very relaxed and friendly as the flight progressed because of the low-stress service for so few passengers."
Cons: "No complaints."

Confusion on boarding - priority passengers should get priority. Service good, entertainment not so good and headphones poor. Meals average. Person behind kept kicking my seat so uncomfortable journey. Disembarking good and baggage fairly prompt.

It was all good as usual .Virgin and Delta work really good together so keep it up and I will be back in December😜👍john harrington

Comfortable flight. Lots of space.

Thanks

Liked traveling with Virgin on the past. This time checking was an issue, meals sucked, we were missed when meals were served. Not a great experience. Will travel in two weeks to the UK but will fly with another carrier

Pros: "Crew was excellent - friendly and helpful"
Cons: "Seats in economy too cramped - I paid extra for next seat up from basic economy which covered our baggage but, for some reason, not seats with more leg room."
Pros: "Amazing !"
Cons: "Nothing all good really"
Cons: "Food"
Pros: "Very friendly crew. The meals are good, nice variety. Hot food is hot."
Cons: "Seats are not the most comfortable and sometimes the screen on the entertainment tv doesn't work that easily."
Pros: "The seats reclined at a good pitch and were very comfortable. The crew were friendly and service was good."
Cons: "I understand that on the night flight, they were trying to keep the lights up for dinner service, but it prevented my toddler from being able to sleep and thus made for a difficult rest of the journey."
Pros: "Premium economy was perfect, smaller cabin with less people, great flight."
Pros: "Craig in first cabin flight crew was amazing. :))))"
Pros: "Crew were great! Neck cushions on chair aren’t adjustable and not comfortable."
Pros: "crew was nice"
Cons: "First time flying with a partner through Delta, so they stuck us on a Virgin Atlantic flight meaning I didn't get my free Delta check in bag (a fee of $60 each way) when I have gotten it every other flight I have ever taken with them. It was also 2 whole hours late in boarding."
Pros: "The crew was maybe average, that was still the best point."
Cons: "Extremely tight space. The food was almost inedible. Awful."
Cons: "The food is not very good at all. One mediocre meal served soon after take-off, then for the rest of the flight tasteless, cardboard pasties and wraps."
Pros: "Good collection of movies"
Cons: "To pay for luggage for international flights while on their website it says i dont have to pay if im going to South Africa. The food was not so great."
Pros: "The food was great. The flight attendants were very courteous and took excellent care of all passengers"
Cons: "Long flight lol j/k can't help that. It was a great flight, no complaints"
Pros: "Virgin Atlantic offers good service at a reasonable price to/from the US to London. Good food service and unbelieveable number of movies and entertainment to choose from."
Cons: "The seating and leg room in economy classic were inadequate. We felt way too confined in our seats and the leg room was a joke. I am only 6' tall and this was unacceptable. We will try to upgrade for the return trip."
Pros: "While seats were close together (little knee space), the plane was 1/2 full, so lots of space in adjoining seats. Nice crew."
Cons: "Delay in boarding - not clear why. Can never get the wireless entertainment system to work."
Pros: "Great, friendly, professional crew, clean comfortable plane. Loved that full dinner and baggage and wine was included in an economy class overnight from DC to London as well as breakfast. Best flight in a long time, will definitely fly again."
Cons: "the tv screen's touch screen capabilities could use an upgrade, it was a hassle to navigate, not very sensitive to touch."
Cons: "The plane seemed to be a little bit old, especially entertaining equipment"
Pros: "Nothing. The whole experience was horrible."
Cons: "I didn't make it to Siem Reap because the first leg of the trip from IAD to London was cancelled by Virgin Atlantic after it was fully boarded. The excuse was that a flight attendant had food poisoning and was unable to fly and so the entire flight was cancelled. The Virgin team seemed unconcerned and showed NO sense of urgency to try and get people rebooked. Their solution was to rebook everyone on an evening flight the next day. If a passenger was only going to London, that was probably fine. But for people with connecting flights -- or like me with multiple connecting flights -- that wasn't acceptable."
Cons: "We haven’t possiblyty to check in online. Crew smell was terrible, ladies used some perfume, some people was allergic to it"
Pros: "Service"
Cons: "Seats in economy are way to small and very uncomfortable if tall. Too close to the seats in front of you. I was miserable all the way to London."
Pros: "The crew was excellent. Flight was quite comfortable. Nice attention to service"
Cons: "I would have appreciated another round of hot drinks."
Pros: "Check in was very smooth with very friendly staff. On board crew was very welcoming and service was excellent."
Cons: "Aircraft configuration of the 787-9 was very poor with 9 seats abreast making the seats very cramped and very poor leg room."
Pros: "Service"
Cons: "The seats are a bit uncomfortable for such long flights. Crue was excellent"
Pros: "Reasonably comfortable for a long jet ride. Helpful and considerate flight attendants."
Cons: "The strange windows that kept it looking like night out until 30 minutes before we landed. I prefer the natural light to help readjust my time zones."
Pros: "On time."
Cons: "."
Cons: "Very small leg room"
Pros: "Good notification re a 30 Minute delay. Obtaining board passes was a breeze and love where I can save the passes to my wallet on my mobile device. Flight crews were helpful, cheerful and professional."
Cons: "With seats being so tight causing an issue when getting in and out of seats."
Pros: "Quantity of food was less for the dinner time..but overall experience was good.."
Cons: "One toilet not working"
Pros: "Aisle/window seating!"
Cons: "My entertainment unit did not work. I was graciously offered an iPad, but declined, however, the picture quality at my son's seat was also iffy. Both my long-haul flights had poor signage for toilets."
Pros: "I liked everything, which is very uncharacteristic :)) At least compared to the big American carriers or the national European ones, VA is a gen - esthetically for sure. Clean, comfy, stylish! Will be my choice from now on."
Pros: "Plenty of snacks and great service, with comfy seats"
Cons: "My luggage did not make it to destination :("
Pros: "Having a not full flight and room to spread out. The Dreamliner is awesome. On time departure."
Cons: "The wifi did not work at all, and I think I was charged 3 times Landed 30 mins early and then waited an hour for the gate, I get that things happen but we have been on the plane for 11.5 hrs. Figure it out!"
Pros: "From check in to landing in London, the gracious, helpful crew impressed us with their attitude and service"
Cons: "Sound didn't work on some of the entertainment choices"
Pros: "On time, everything normal."
Cons: "Seat space so small that my knees were up against the next seat, even without it tilting back."
Cons: "If the luggage fees were to be included in the price, I would have gladly chosen Emirates for its comfort at that price."
Pros: "great food and service!"
Cons: "It got a little cold in the cabin for a few hours."
Cons: "I did not get the requested meal. I had requested Asian Veg meal. I had reconfirmed that Virgin Atlantic Kiosk at Heathrow airport as well. In flight when I asked cabin crew they said they didn't get any request. I was hungry whole flight. Very bad experience."
Pros: "Superior comfort, class, and style. The crew was friendly and accommodating, the pilots kept you up to date with flight info and departure/arrival time (and kept the seat belt light off almost the entire trip), the food was delicious and offered throughout, and the entertainment was top notch. Seats were comfortable (we had bulkhead row Space+ and they were worth every cent for the international long haul from LAX-BNE and SYD-LAX) and everyone got a pillow/blanket. We got premium noise-canceling headsets, water, and a little care kit including an eye mask and earplugs and a pen to fill out your travel documents. The overhead bin space was huge and we got two free checked bags of luggage up to 50lbs each (I don't know of that's standard or not, or if it came with Space+ seats). SERIOUSLY the best airline."
Cons: "Absolutely nothing. For a long haul flight, Virgin Australia is TOP NOTCH!"
Pros: "Not much not to like about this experience except for cramped seating in coach."
Pros: "It was a great experince we enjoy the flight other than the delay on the luggage"
Cons: "one of my luggage was lost and delayed for 2hrs. We waited at the Airport for the luggage to arrive."
Pros: "Everything except the seating - far too cramped now"
Cons: "Seating! Seats getting ridiculously tight"
Pros: "There were lots of choices of movies. The flight was only half full, so I got two seats together to stretch out."
Cons: "The cups for water and juice were very small."
Pros: "Major issue: No information in advance of problems associated with transfer at Heathrow that required going from Terminal 5 to Terminal 3-- requireing a lot of walking, stress, time and security checks."
Cons: "It was late leaving."

No entertainment or food service on this flight. Hence rating.

Every thing is fine

We paid for preferred seating for extra leg room. On 3of the 4 flights the preferred seating were regular seats with no extra leg room. It was deceitful to advertise those seats at preferred seating. I would not have wasted my money paying extra had I known what I was getting.

Pros: "Crew from Washington to Cancún were extremely rude"
Cons: "Smile"
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Cons: "Worst airplane i have been on since 2007"
Pros: "Quickly moving through the airport."
Cons: "Take out old planes. It was really run down."
Pros: "Reliable - on time - good service - made up time for a late departure"
Cons: "All Good stuff"
Pros: "Boarding so efficient we left early and arrived super early."
Cons: "WiFi on plane dropped out a lot."
Pros: "The plane was nice"
Cons: "I’m still sitting in Minneapolis so I would have liked to be at my destination. And I had to pay for the overnight accommodations."
Pros: "Entertainment was awesome. Although airlines are stingy with snacks, Delta had a good overall selection and very generous."
Cons: "Something that cant be changed overnight, however, there should be a little more Aisle space for folks pass through as my shoulder was getting beat up after every passing person and cart."
Pros: "Crew was friendly."
Cons: "Wish the seat was more comfortable. Landing was jittery and bumpy."
Cons: "Delta needs air conditioning on their flights"
Pros: "Crew was awesome. Very friendly."
Cons: "I’m 6 foot tall and I found my seat space feeling crowded. I found myself wishing for just 2 more inches of legroom. It feels that airplanes are being built for quantity of passengers, not quality of flight."
Pros: "Crew was amazing."
Pros: "The flight attendant from IAD to MSP called Bernadette was wonderful!"
Cons: "Delayed"
Pros: "Super comfortable seats. Lots of movie options."
Cons: "Food was not very good"
Pros: "Flight was smooth, arrived early..crew was prompt and courteous."
Cons: "Seating poor — crowded and little leg room"
Pros: "Crew and entertainment options were great."
Cons: "Cabin was very loud, with jet engine noise. Could not block it out. Seats were not comfortable."
Pros: "Standard Air France flight. My wife and I like the Airbus 380."
Cons: "The flight left two hours late. Apparently this happens a lot with this flight these days because it's an Airbus 380 coming from Paris to Dulles and turning around. The incoming flight was two hours late, so the departure was late. Our arrival in Paris was late. We made the flight, but our luggage didn't. Our return flight from Paris to Dulles was half an hour late because of people from connecting flights. We arrived about 30 minutes late, but no big deal (unless you had a connection)"
Pros: "I earned miles for it."
Cons: "It was an old 767 that either needs to be gutted and redone, or sold to FedEx for cargo. The entertainment systems were relics from 2002, and barely worked. USB port, nope. Then they ran out of food and booze (wine mostly), so they made the nonrev employees go without, which was awkward gif the rest. But the kicker was that they lost my luggage. I told them that it hadn’t been boarded ten minutes prior to pushback. The Venice folks were very excited to be able to show me exactly where they list it (because of the RFID bag tags)... doesn’t do me much good... 10 miles away or 10,000 miles away, I still don’t have my “stuff”"
Pros: "Fly attenden alwas with a beautiful smile"
Pros: "Nothing particularly stands out. I did arrive safely."
Cons: "First class did not come with lounge access? Drinks were not cold. Bathrooms were falling apart and came with a disgusting odor. Time to retire these aircrafts."
Pros: "Attentive, respectful and nice crew, swift take off and landing and awesome views"
Cons: "Nothing. Everything went well"
Pros: "The check in reminder is easy and helpful"
Pros: "Flight attendants were nice based on the situations beyond their control."
Cons: "Flight was delayed for about three hours, due to mechanical issues with the second engine not starting. We sat on the the plane for over an hour and half. Some people that missed their connection flights were offered hotel stay. Others that had no connection flight was not offered anything for the several hours of delay that occurred."
Cons: "Tv"
Pros: "The chekc in person was very helpful."
Cons: "The plane was too hot and the pilot did not accommodate the passengers request. More than just me made the same request."
Cons: "They changed my departure hours three times"
Pros: "That I landed safely"
Cons: "1st class was horrible."
Pros: "Smooth flight Courteous"
Cons: "On a five hours flight a two dollars sandwich wouldn’t hurt!!"
Cons: "I have traveled with my luggage plenty of times through airports and the flight from washington to jacksonville, my luggage came back to me cracked and broken. I was surprised that Delta handling was worse than any of the cheaper flights I normally take and will not be checking any baggage with Delta again."
Pros: "Great and friendly crew"
Cons: "baggage rules, check in with baggage, change fee for flight when it was not customers issue that caused the 5 min delay! Unable to reach reservation desk on line or via phone (neither was the gate agent)"
Cons: "Seeing as I’m still waiting for my flight, more than five hours later I am not inclined to rank it highly. This airport is an embarrassment and I will try my best to never fly Delta again. Weather is no excuse for this."
Pros: "My flight was canceled but Delta rebooked me on a flight leaving at about the same time as my original flight, which arrived just a little later than originally anticipated"
Cons: "My original flight was canceled"
Pros: "Service of all the flight staff, smooth flight, and early arrival. Staff was very courteous and helpful"
Cons: "Nothing really. It was an uneventful flight with good service"
Pros: "Special staff great pilots snacks free movies safety"
Cons: "Everything was great"
Cons: "Delayed two hours"
Pros: "Got to my placs"
Cons: "Lol put the two fattest people next to each other"
Pros: "The fact that there were no snakes on this plane :-)"
Cons: "Same issue... there were no snakes on the plane :-/"
Pros: "Flight attendants and cookies. That's it."
Cons: "We left DC late because of Delta's inefficient boarding process. We landed in Atlanta late. Our flight to Sioux Falls left early, without us. My pregnant wife and I made it to the gate 4 minutes before the scheduled departure and they told us the plane was already gone and there was no way for us to get on the plane. Our bags did make it to Sioux Falls, so my wife didn't have her prenatal vitamins, , we had no clean clothes and we were forced to spend the night in Atlanta. The saddest part of yet another terrible experience with Delta was that they offered us a "discounted" room at a terrible Howard Johnson for $72. I looked online and the same hotel was $65 to book on Kayak. So basically Delta was trying to scam us after they screwed us. Thanks Delta! Instead we paid $200+ to stay at an airport hotel. Every time I fly Delta I regret it, yet occasionally I get forced to take their awful airline to get somewhere I need to go. It never fails to add another bad Delta experience to my long list of failings from this SAD!!! airline."
Pros: "great flight - easy and quick as always"
Cons: "the power on the plane didn't work and there was no entertainment"
Cons: "There delay"
Pros: "The crews were very friendly and everything went as planned. It was a nice flight."
Cons: "I didnt like that my flight was canceled and rebooked for no reason. This created me big problem in Athens that they couldnt find my ticket in delta. Also I didnt like that i had to stand and wait for 3 hours in the line because my flight was canceled but no one could let us know if there gonna be any flights within the day. I slept in the airport because i couldnt find a hotel to spend the night close to the airport. They were all full and i had no time to find one since I was waiting there for 3 hours with no informational. I slept on the floor and delta didnt even offer us a blanket. That was my worst trip ever."
Pros: "The flight was smooth and the food selection was surprising delicious. The crew was very attentive."
Cons: "The leg room was much less than the last time I flew Virgin (booked via Delta) and made for an uncomfortable trip. Could not sleep as a result. If you're tall like me you'll need to book a higher seating category."
Pros: "Everything was great"
Cons: "Nothing everything was fine"
Cons: "paying extra for leg room and checked bags"
Pros: "Great staff , amazing dinner, and the entertainment screen size was best"
Cons: "Seats could be a little bigger"
Cons: "Frankfurt connecting flights, security, and Passport control are terribly inefficient, with unclear guides to get passengers from B gates to A gates."
Pros: "Crew was very attentive and professional."
Cons: ". The economy seats on the Lufthansa A350 were extremely uncomfortable and seemed excessively narrow as well has having cramped legroom. I could not get comfortable let alone sleep, and my backside felt like I had been sitting on a park bench rather than a long haul coach airline seat."
Pros: "Nice crew"
Cons: "Better food, some entertainment, better bathrooms"
Cons: "It’s an international flight. It is what it is!"
Pros: "Crew was excellent."
Pros: "the crew was good , seat was not so comfortable"
Cons: "seat need to be more soft for a trip during 8h //"
Cons: "n/a"
Pros: "My flight was delayed four hours, so I missed my connection to Sofia and had to re-book for two connecting flights instead of one, which makes for a long, tiring trip."
Cons: "I understand the delay due to weather conditions, but I wish I was rebooked for one, not two connecting flights. Now, instead of flying directly to Sofia from Frankfurt, I have to go to Munich first and then to Sofia, which makes my trip 9 hours longer"
Pros: "nothing"
Cons: "better accommodation of passangers"
Cons: "They told us there were no earbuds so recommended using our own. Our children had left theirs at home so they ran to get a $20 pair nearby. But the the plane DID have the buds; what we did not have were blankets — the crew said none were to be had."
Cons: "Fight could have been on time! It was over 45 minutes late, because of the crew"
Pros: "Efficient boarding, friendly crew, nice range of entertainment options."
Cons: "An economy seat is an economy seat ...."
Pros: "Very amazing"
Cons: "N/a"
Pros: "Baggage arrived with me. Upgraded to First Class because so many of those passengers got other flights the night before."
Cons: "Original 5 pm flight was cancelled because there was no Crew or plane, even though it’s a United hub. Though flight cancelled early, United could not get me home same day so provided hotel and meal. Next day flight scheduled 7:05 then 8 am, but even that time came and went without boarding. 15 hours delayed and no hurry getting the plane to depart at the stated time. Total lack of customer service and concern"
Cons: "I did not like the fact that the United flight I came in on was over a MILE of corridors away from the outgoing flight."
Pros: "Touch screen is sharp and responsive."
Cons: "Food is ok. Used to be better a few years ago when the cuisine had a Southest Asian fusion style."
Pros: "Cleanliness"
Cons: "It was late by 1 hour. Food was not enough. Was hungry since dinner was late due to delayed flight and breakfast was served at lunch time of MUC. Electrical outliets did not work in the flight and had problems in MUC for GPS."
Cons: "Water only and.. I had to asked for it. No snacks or other drinks in my eighteenth hour of flying back from Poland :(("
Pros: "Underseat AC power and USB power was the highlight of the trip."
Cons: "Food portions were tiny. Totally dehydrated at the end of the flight, and water was passed out in 100 mL servings. Insufficient space under the seat for a backpack."
Pros: "I wasn't expecting free in-flight movies and meals, which were very welcome"
Pros: "Everything on the flight was very efficient and organized—the boarding process, the excellent and pleasant service, the food, and the entertainment selections. Thank you for making a long flight enjoyable."
Cons: "Food wasn't the best but did honor my special diet request."
Pros: "Impecable service. Even worth flying through FRA."
Cons: "Nothing. Everything, as always, great. Keep it up."
Pros: "The food was good."
Cons: "The seats were not too comfortable and the video screen was small."
Cons: "Walked a very long way in Frankfurf airport to transfer to another flight."
Pros: "SERVICE"
Pros: "They were nice"
Cons: "They were good"
Pros: "Service was very good, flight was very smooth"
Pros: "Restful flight"
Pros: "The service by the flight attendants was very good starting from the welcome to the end in spite of the fact that it was quite late night flight. Also by fortunate luck I had the chance to sleep as the next three seats to me were all empty in the middle block, which made the whole trip less exhaustive."
Cons: "If the seats next to me weren't empty and I couldn't lay down across all of them it would have been a difficult flight as the economy seats are not even close with economy comfort levels of other international airlines like Turkish Airlines especially the seat pitch size. Entertainment choices could be improved by more recent movies. There were very few selection."
Pros: "On time all the time"
Cons: "Food getting worse year after year."
Pros: "Our experience flying with Lufthansa was very pleasant. The overall process of making connecting flights through Frankfurt was much easier than we had anticipated. The cabin crew was friendly and courteous. I will be flying Lufthansa again."
Cons: "I would appreciate the ability to check in and get seat assignments at least 2 days before the flight. The day before traveling can be fraught."
Pros: "Smooth flight"
Pros: "My parents had a wonderful experience. Very professional and courteous!"
Pros: "The agent at the counter was very very helpful and accommodated us to an earlier flight. That saved us lot of time."
Pros: "Fast boarding, on time"
Cons: "Too cold in plane, announcements too loud"
Cons: "Boarding three planes to three different destinations from the same gate is very confusing."
Cons: "It was too cold on the plane."
Cons: "We were in economy class. It looked like the seats my wife and I were in were smaller than the surrounding seats. The seat I was assigned was also more narrow than the one my wife was assigned. I am tall, and could not move my legs for the trip. Also, the seat controls were on the inside is the seat. I could not move at all without turning on the overhead light or screen."
Pros: "The crew was very attentive. I did not want to eat the food and the crew offered me fruit. Great A/V options."
Pros: "Short and Smooth Flight"
Pros: "They handed out baggage claim tickets for the larger carry-on items early so that passengers had plenty of time to rearrange their items, as long as they arrived at the gate in time."
Cons: "They had 3 flights boarding through 2 doors that led to one hallway, which was very confusing. It took quite a while to retrieve the checked carry-on items, with the effect that most of the passengers were lined up down the causeway tube, waiting. The seats are so very cramped on these puddle jumpers; this was way too long a flight for cramped seats that don't recline. The entertainment was wifi that never really worked."
Cons: "We missed the connection so never made this flight."
Pros: "Best crew ever. By far most friendly staff and excellent service."
Cons: "Nothing that I know"
Cons: "This was a united flight. The personal was not helpful, only in helping me communicate with the airport in Rome to change my flight. I had to pay 97 euros for this change. I am upset and think it is not fair that I need to pay for a problem united had with their flight. I also think star Allience failed as they were not able to resolve the problem with their partner airlines."
Pros: "When we fly Trans Atlantic, we always hope it will be with lufthansa! Sometimes they use united as a carrier and it us never as good as lufthansa!"
Pros: "Everything else was fine."
Cons: "I had paid for comfort seats ($140) extra. When I checked in at gate I was given another seat assignment (without explanation). It turned out to not be comfort seat, in fact it was the last row in the airplane. Had to get eh gate agent back, which was not fast. She said flight was full and a family had been spread out. I understand, but you can't just bump me from a paid and selected seat to a standard seat, especially on transatlantic flight after paying $140 extra. There was no apology. She went back to gate and little while later came back with a comfort seat. Some people seem not to have shown up as the seat next to me stayed open as well. It was very poorly handled."
Pros: "All is good expect confort and food"
Cons: "Food"
Pros: "Great service, food, crew."
Cons: "Seats too small, very uncomfortable."

Problems with the in-flight wi-fi (none) and the flight info (none). However, movies worked fine and the selection is exceptional.

Both airports totally understaffed. Awful experience.

Pros: "So rude crew"
Pros: "The seats were so comfortable"
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!"
Cons: "Still don’t have my luggage yet"
Pros: "Everything works and quick to get to destination."
Pros: "Seats were super comfortable, bigger than most planes with extra leg room. Food was excellent and fresh, amazing Dutch cheese sampler was divine. No nonsense staff who had all connecting flight info on hand when we arrived in Abu Dhabi. KLM staff were friendly and efficient. Fabulous airline."
Pros: "The aircraft"
Cons: "No overbooking next time!"
Pros: "Comfortable seat, great crew."
Cons: "Flight delayed, no USB port and no entertainment"
Pros: "The crew was great. The soecial meal request was hadled well despite oversight."
Cons: "Soecial meal request was made in advance but overlooked. Did not mind it so much as eating less is not a bad idea! To err is human."
Pros: "No delay and nice staff"
Pros: "Nice attention and good food. Plane and seats are confortable"
Cons: "Dozens of high school students screaming and climbing onto seats, crew did not intervene."
Pros: "Crew was fantastic."
Cons: "This was the most narrow airplane seat I’ve ever experienced. So uncomfortable."
Pros: "Like the overall KLM experience"
Cons: "Food could have had better quality and the stewardess served it all at once versus in the various courses."
Pros: "My seat at the window was great and the staff really friendly and courteous!"
Pros: "very attentive crew"
Cons: "Only ham sandwiches on offer! I'm not demanding and would have been happy with cheese."
Cons: "Turn the lights on early making it hard to sleep"
Pros: "Flight duration"
Cons: "Very stingy with the drinks Cramped seats"
Pros: "The constant smile conferred by flight attendants through the entire flight."
Cons: "The boarding was a bit disorderly. Lanes for zones 3 and 4 were not clearly indicated."
Pros: "Gaps between seats are very narrow."
Cons: "when serving drinks, cabin crew limited to serve liquor only once and it was poor service."
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: "Light snack and complementary wine"
Pros: "Friendly hostesses"
Cons: "Flight was delayed 3 hours"
Pros: "Very pleasant, professional crew"
Cons: "Very slow check in. Mainly because other passengers obviously don't read instructions re: weight/contents of cabin bags etc. Would be helpful if there was additional staff to deal with them away from check in desk. This would mean that others did not have to queue for 25 minutes because the check in girls also had to deal with them"
Pros: "Overall booking and airport was ok. Food was also actually quite good."
Cons: "A comfort of the seats... well its economy class in the end. Entertainment was just dreadful - small screen with visible pixels - I was unable to watch any movie."
Pros: "The flight was perfect! Great food,movies and I even got to sleep !"
Cons: "All was well!"
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: "I slept pretty much the whole time"
Pros: "Food was excellent, service from staff was friendly, and entertainment options were great."
Cons: "Not a lot of shoulder room being in the middle seat. But it had adjustments options for a lot of other things which were good."
Pros: "Great food"
Cons: "I paid a top price for my ticket and expect the advertised amenities to work. Upgrade or replacement for entertainment system."
Pros: "I enjoyed the attention to detail and comfort. Helped to make the flight easier to handle."
Pros: "Food was just fine, movie selection very good"
Cons: "Uncomfortable seat cushions, lights were truned on too early (1.5 hours before flight landed)"
Pros: "Nothing"
Cons: "Super delayed. Could have fixed the issue BEFORE we were sitting on tha plane for TWO hours"
Cons: "They stole my money"
Pros: "787 is a great airplane. The 3-3-3 seat configuration leaves enough seat width to be just comfortable in coach."
Pros: "The last two times we connected in Amsterdam to Humberside our luggage was delayed. This time it wasn’t. The simple things give the greatest satisfaction"
Pros: "Easy Boarding"
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: "Great crew service. Among the best ever."
Pros: "Easy airport business"
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: "Overall, my trip to Cardiff via Amsterdam was smooth and delightful. I've flown a few short trips this summer and I was pleasantly surprised to find KLM still offered complimentary snacks. What a refreshing change!"
Cons: "There was no entertainment which is why I assigned that category only one star. The boarding process in Amsterdam could have been a bit smoother. Announcements were no clear."
Cons: "Did not get the luggage from connecting flight from Amsterdan to Basel"
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 the plane didn't have wifi / USB"
Cons: "I slept didn't have snack offered and no entertainment"
Cons: "I missed my flight because of MU"
Pros: "I liked the leg room, I liked the customer service of the crew, smooth flight."
Cons: "Both ways up and down I struggled with over-head luggage space. We were allowed a cabin bag and a small hand-bag in the flight but as we were among the last half of the passengers to board the flight we couldn't find anywhere to keep our luggage and the crew had to take them away from us to store them somewhere at the back far away from our seats. As a result we had to wait until all the passengers got off the plane to get back our luggage and we were the last two passengers to get off. Unpleasant!"
