"Great customer service. Safety and cleanliness. Fly delta."

"2hours delayed and didn't give notification right away 🤷‍♀️. I even lost my food to rush to go to the airport. Paid $60 for seafood plate ending just leave it almost halfway on my way to the airport find out the flight was delayed. I wish they have more accurate policy to let passengers knows for any problems about the flight as soon or as early they can"

"I like that I got to my destination safely."

"The TSA screening is absolutely unnecessary. It is dehumanizing and has been proven to be in-effective!"

"Anyone that purchased a Delta 1st Class seat should have access to the Delta Sky Club. My wife and I purchased 1st Class tickets for a Delta flight from SeaTac to Washington Dulles but were denied entrance to the SeaTac Delta Sky Club because we did have an American Express card."

"Really accommodating staff, and on flight amenities. I would fly with Delta again."

Pros: "The seats were very good. The crew was helpful and friendly."
Cons: "We had a connection in Detroit. The flight from Seattle to Detroit arrived about 30 minutes late, and we barely made the connection. Apparently Delta had not told the Detroit-Boston flight to wait a few minutes for us. We did make the connection, but we arrived at the gate with no seat assignment (we had been bumped the day before from our original flight because of a mechanical problem) as the plane was loading. Had we missed the flight, we would have had to spend the night in Detroit and go to Boston the next day. Delta should have told the gate agent that we were coming."

Pros: "Crew attentive, professional, appeared to be enjoying job with full plane."
Cons: "The mew food boxes in furst class taste terrible."

Pros: "Sitting in the exit row"
Cons: "Nothing"

Pros: "Great crew."
Cons: "Mask enforcement"

Pros: "Clean safe comfortable plane seats. friendly staff."
Cons: "A small credit for miles as the Wifi didn’t work."

Cons: "Having cocktails available on-board"

Cons: "The exit row that I paid up for, for leg room, didn't have extra leg room. First world problems."

Pros: "Crew was awesome!"
Cons: "The boarding did not go on time. An announcement about why would have been nice. Still made it on the flight on time."

Pros: "This was a redeye flight which are never the best. We upgraded to first class for a chance to sleep. The sanitizing of the aircraft was beyond expectations. The personal wipes were a plus so we could clean the areas around our seats to our satisfaction. The individual snack bags are a great idea to minimize handling."

Pros: "It was nice that the plane was not packed full."
Cons: "Box water instead of water bottles. The seat wasn’t very comfortable since it wouldn’t recline."

Cons: "The Seattle gate agents never said which flight they were calling and since neighboring gates were boarding at the same time it was very confusing and rather chaotic."

Pros: "Crew was very attentive. I appreciated the extra spacing between passengers."
Cons: "I would have liked to see alcohol served."

Pros: "There was an amazing variety of tv shows and movies. That is essential for long flights like ours was."
Cons: "For long haul flights, I am used to being offered a pillow/blanket, even when sitting in economy."

Cons: "There should not be a pay wall around the internet in today's day and age"

Pros: "Everything from hospitality to the ease of the flight. Captain communicated to put all at ease during this time in which this pandemic has gotten many fearful of flying. Great landing as well."
Cons: "Everything was great!"

Cons: "flight left without 1/6 of the passengers. ¯\_(ツ)_/¯"

Pros: "Crew was great, flight in general was okay"
Cons: "The plane itself and seating was filthy, some unknown substance fell on me from the vent above, there was a bunch of crumbs in the seat buckle that fell out all over my lap when I fastened it. I'm not sure the tray table was wiped down, or at least not very well. The in-flight tracker was completely incorrect, I was on a 4-hour flight and it read 14 hours and counting throughout."

Pros: "Nice crew"
Cons: "No leg room for 6’6” person."

Cons: "We weren't alerted there was a chance of delays. Over two hours late."

Pros: "I love all the complementary stuff on flight"
Cons: "Better ear buds"

Pros: "Everything! Thank you"
Cons: "Nothing. Thanks"

Cons: "Food really bad on both segments."

Cons: "2 seats and neither tv/entertainment centres worked....unacceptable on a 10 hr flight!"

Cons: "Compared to Virhin Australia crew, Delta staff seem almost poorly trained in comparison. For example, Drlta crew don’t check your pass, don’t immediately move down the aisle to move along tourists busy discussing their seats and then line up for Boarding seems chaotic at best."

Pros: "The entertainment was nice."
Cons: "If the screen wasn’t behind the seat. I could hear the tapping of the person behind me."

Cons: "Departure delayed by 1hr30"

Cons: "N-S"

Cons: "Missed connecting flight because the first flight was delayed by 2.5 hours. I didn’t get the comfort seat I paid for because of this and was not given a refund for it."

Pros: "The crew was very professional, hejpful and had good attitude towards the passengers. This made the flight easy and enjoyable."

Pros: "I think they flew so fast. We could land almost on time even though we departed a hour late. Airplane was new and clean."
Cons: "Boarding was chaos. They overbooked 25? 45? Anyway, they are in panic. They tried to request ppl to take next day flight by giving away 300 gift card etc. the ppl who were told there are no seats upset and arguing at the gate. Flight was delayed for one hour. Once we are on airplane, they are still shuffling seats around, so ppl cannot move forward. Just standing there for 10mins waiting for things to settle. Flight attendants did not give us a headphone. (I have a headphone for iPhone X so I could not connect it to their entertaiment system.)"

Cons: "Over an hour delay before boarding due to supposedly bad weather. Because flight was overbooked they were offering $400 gift card to change to standby on another flight. If you didn’t make that flight (evening), you’d be confirmed on a flight the following morning with one stop in Detroit (we booked a nonstop to Chicago). Uh, no thanks. Then to top it off, we’ve landed and been told that it will be at least an hour before we can deplane due to no availability at the gate (it’s 1145 pm right now). All this plus their new policy of not allowing us to select our seats because we bought the cheapest tickets. Really Delta? You go ahead and cater to the rich and I’ll choose to fly with another airline."

Pros: "This was our first time flying Delta and it was a very pleasurable experience. Boarding was very straight forward and the seats allocated comfortable. A surprise for us was being asked if we would like to move seats from the back of the aircraft to Comfort Economy (we think it was to do with weight balance! but appreciated very much none the less). The flight attendants were very professional and helpful, as you would hope all attendants on all airlines would be. We'd gladly fly Delta again anytime."

Cons: "Partner site said it was Aeromexico. First flight was delta so different check bag policy for internal flight that cost me $80. Screw you all"

Pros: "Nothing really"
Cons: "Flight delay further to the 30 minutes additional 20 min due to crew being not there"

Pros: "Nothing, they didn’t care about you or to help, the llady was so rude and unfriendly, this situation ruin my whole trip"
Cons: "I call in advance to paid the fees for baggage, I call Aeromexico because was the main airline for the fly, but Delta at Seattle made me paid again the fees for baggage’s even by phone they said that I didn’t need to paid. BE AWARE AND CAREFUL BECAUSE THE LADIES IN THE FRONT DESK didn’t even look the paperwork that you have in hand, they only want to charge you saying that your payment thru Aeromexico didn’t help you in the 1st fly. How this can happen when Delta and Aeromexico are two subsidiary one of another ?"

Pros: "Boarding is easy as always, I like Delta's system."
Cons: "I had a seat by an exit door. I was incredibly uncomfortable the entire flight due to the cold air comin in and hitting my feet / legs. Two coats and a blanket weren't enough to remedy the issue."

Pros: "It was whatever"

Pros: "Almonds"
Cons: "Seat, did not get upgraded"

Pros: "Great service, very comfortable."

Pros: "The service on board is always GREAT! in Aeromexico"
Cons: "The flight was canceled and we were put in another flight next night. But the staff in Buenos Aires run the situation chaotically and made mistakes that infuriated many passengers. They need more training to learn how to say "I am sorry" more often and know how to avoid getting into arguments with passengers."

Pros: "Food selection and quality were fine. I also enjoyed the entertainment options. Seat area was comfortable and spacious."
Cons: "The flight attendants were uniformly rude and nasty to passengers from start to finish. As I boarded, I asked for a piece of art to be stored in the wardrobe compartment. This was treated as an inconvenience. During and after boarding, flight attendants addressed passengers rudely when encouraging them to take their seats in a timely fashion. Later, when my seat mate politely asked a FA to repeat the food options, she asked, "Excuse me?" several times and seemed very irritated to have to repeat the choices for him. Also, near the end of the flight, a pillow was on the ground and a FA asked those seated in my row to pick it up. We responded that it wasn't ours and she said something to the effect of, "Oh yeah? So how did it get there?" (Maybe because someone else dropped it and we didn't notice?) The FAs seemed irritated to serve passengers at all. Each time they passed through for beverage or meal service, I felt like I was imposing on them. I have never witnessed anything quite like it. Makes me wonder why they were all so upset and and felt it appropriate to speak and act disrespectfully toward customers. (Delta, do you have any insights?) I hope they all got a good night's rest after that haul."

Pros: "Good Snacks, crew is friendly, toilet was clean and we arrived on time"
Cons: "Nothing"

Cons: "As a Platinum AFK/KLM Skyteam member I was NOT allowed to use the Delta Lounge. On the flight the meal choice was poor and the staff were not really geared to serving regular clients. The movie choice was poor. I expected better!"

Pros: "Lufthansa is a great airline."
Cons: "Food was so hot that it was difficult to remove the packaging to be able to eat the pasta.... Desert was ok, brownie was real hard and too sweet...."

Cons: "The least leg room in any flight I’ve taken. We had requested vegetarian and the flight from Frankfurt to Nairobi gave our meal to other passengers.they told us we had to eat the best dish or nothing. This on an 8 hour flight."

Pros: "Staff was extremely nice and helpful"

Cons: "Check-in Seattle was ill organized and folks cut and groused"

Pros: "The crew was friendly"
Cons: "Maybe not have my luggage lost and get rebooked to a later flight for no reason"

Pros: "Flew Business Class with miles program (United). Lufthansa always gives good basic flight experience. Watched two movies so saved some time at home. Lounges are getting better every time I fly. They are especially good, understandably, in Frankfurt."
Cons: "Nada. They get the job done."

Pros: "everything from the boarding and check-in process to in flight comfort."

Pros: "The crew."
Cons: "The airplane arrived over 45 minutes late."

Pros: "Crew were great. Very friendly & helpful"
Cons: "Lufthansa really need to serve something better than high school cafeteria grade food"

Cons: "No proper wheel chair assistant and made passenger miss the flight. Airlines have to take extra steps to make wheel chair passengers to reach the gate safely and on time."

Pros: "Crew were friendly, boarded promptly"
Cons: "Food could have been better."

Pros: "Tv screens, free beverages, frequent service"
Cons: "The single most cramped and uncomfortable flying experience of my life. The chair in front of me recliner lined to 4 inches in front of my nose. Couldn’t move legs or arms for 10 hours because it was so tightly packed. I couldn’t believe it was legal to fit that many people that closely together."

Pros: "My seat was next to bathrooms when everyone start using it start smelling too much very uncomfortable sitting there. Food chicken was very salted, they run out of drinks 10 hours flight dinner served at begging no snacks or anything till 2 hours before landing"
Cons: "At least air fresheners in bathrooms or something better so passengers can sit comfortably"

Pros: "The flight attendants were friendly. The seats were new. The movie selection was good."
Cons: "The scrambled eggs for breakfast appeared to be powered eggs, or overcooked eggs. The storage bins for the luggage were very small for the middle seats (aircraft was an Airbus A330-200). After several hours of flying, there was trash in the aisles and on the toilet floor. The toilets were dirty and not cleaned. Finally, the toilets ran out of paper towels and tissues with 3 hours to go in the flight, and they were never refilled. The flight attendants put a roll of toilet paper next the sink to use for your hands."

Pros: "Lufrhansa is a fantastic airline"
Cons: "The seat pitch and width were too small."

Pros: "flight attendant found me a seat away from the screaming babies."
Cons: "I was surrounded by about 6 babies. This is not acceptable for a long flight! I would like to have options as to where I sit. There should be a baby section where families pay more to be in a section on their own!!"

Cons: "Very bad food"

Pros: "Good plane and service"

Pros: "Crew was very attentive and efficient. Flight was ready to leave on time but was delayed due to security concerns at Sea Tac airport; even though the flight arrived on time."
Cons: "I did not have a problem with anything."

Pros: "Food was ok. Beer offered at no charge. Lots of entertainment options"
Cons: "Plane was HOT no air and economy was unbelievably cramped and uncomfortable. 9 1/2 hr flight was torture"

Pros: "Staff were nice and friendly."
Cons: "The plane was dirty. The seatback was not clean, and the tray table was stained. The 9-hour flight did not have any USB ports or outlets for charging. The touchscreen did not work well, and my seat would not move forward or back without me pushing or pulling it. This"

Pros: "It was an overall good experience. Very well organized. Since both legs of the flight we're half-empty, it was easier on the crew too. They were nice and helpful. Everything very clean. Entertainment choices were good. Had an excellent entertainment system."
Cons: "Food was kind of bland."

Pros: "Crew is very friendly, seats are extremely comfortable and good room overall, comfortable flight."
Cons: "Hi, To be honest, it was embarrassing to serve that dish on such a major airline. Chicken with bbq sauce and corn or something like that. Was distasteful I couldn’t take more than 2 small bites."

Pros: "The Entertainment, the Food and the nice and friendly manner of all personell."
Cons: "Nothing."

Pros: "Such great personnel in the air - can't say enough how much I appreciated them."
Cons: "The airline as a whole, however, encourages you to book with them under the reasonable assumption that connecting flights with Lufthansa will be achievable. Now that I've seen Frankfurt, There was no way they could actually expect any of us to make our connecting flights. And they offer no compensation. When I did get another flight, it was terribly delayed. Talking in line with regular European travelers, they said they expect it. Also met several fliers at the service desk attempting to connect via entirely different routes, all having the same experience."

Cons: "Crew was not nice at all. They would skip us along the way while serving others, or even drop ice on us, and never said sorry once (instead, they would say it's only ice, or if I want 2 since they skipped me already twice when serving tea unlike the passengers around me on both sides). We paid nearly $6k for the 3 of us, but the crew made us feel as if we paid nothing. The entertainment system did not work well, and most of the time the movies refused to play. We were always suggested to restart, and were not even given free access to internet as an alternative. No one ever apologized for anything in the entire flight, it felt like this flight was a favor."

Pros: "Flight went smoothly boarding was a little delayed."
Cons: "Getting to gate 10 minutes after boarding time and no one had boarded yet."

Pros: "Friendly crew. Flight left on time"

Pros: "Everything was generally good and normal"
Cons: "Except the plane was roasting and had no vents"

Pros: "Service , on time"

Pros: "service, care for my 85 pound dog and his kennel while traveling halfway across the globe! Thank you! Flight was smooth, services on board excellent."

Pros: "Aircraft crew was decent."
Cons: "Seattle to Frankfurt aircraft was the dingiest and most crammed aircraft I have ever used on an international leg. The seats were tiny so much so that some other passengers were not able to fit in! The lighting was gloomy, restroom dirty within the first hour of the flight, no space to keep any magazine or books on the back rest of the seat in front of you, etc. Overall - such a bad experience. Not expected from Lufthansa, especially as I have had great experience with Lufthansa earlier."

Pros: "The view - flying low over the northern extremes of Canada was superb. Thanks to the pilots etc."
Cons: "The flight was late arriving at Frankfurt. I requested a notification to my connecting flight. Crew member frowned, turned away and in formed me, "We don't do that". I ran to the Connecting Lufthansa flight and barely made it on time."

Pros: "Boarding was done very quickly. Unlike the norm nowadays, people weren't cramming every single inch of space in the overhead. In addition, the flight wasn't full so my travel companion got to enjoy a full row to himself while I enjoyed an empty seat next to me to stretch out. The food was very good. The staff came by quite a few times to offer orange juice or water. The entertainment syren was excellent. I watched four full movies on the trip and have in mind at least a couple more for the return leg."
Cons: "Not a thing."

Pros: "Lots of room on a 747 - Lufthansa will probably retire them all soon. They handled my special meal request online and loaded the meals on the plane."
Cons: "The crew didn’t bother to confirm who had requested the special meals, and they perhaps were confused by the size of the wide body rows, so they served my dinner to the passenger in the window seat (seat K) instead of me (seat H) By the time I realized what had happened, my row mate had eaten half the meal. The crew also rammed my knee with a beverage cart while I was dozing. Not the best showing ever..."

Pros: "service, good quick flight"
Cons: "late departure in Frankfurt; high noise level of the Embraer plane;s engines; failing AC in the cabin"

Cons: "There was light turbulence in some parts during the flight but the captain never turned the "fasted hour seatbel on" sign which was strange."

Pros: "The crew were very helpful and polite. The seats had plenty legroom. The food was excellent, and entertainment was also very good. Most importantly, there was no delay."

Cons: "Will newer agan fly business with Lufthansa!! It's not business at all just regular econom seats with short leg room and casual service. They should be sorry for that kind of business!!"

Pros: "Flight attendant was very helpful. She went out of her way to bring me a special tea. Large selection of entertainment."
Cons: "Food could've had more healthier choices. Also, kid-friendly food would've been a plus. Not enough leg room. Headphones were only working for one ear which is really bad for the ears. Air conditioning was really turned on really high and gave me a headache and the sniffles. I started throwing up during landing time. Horrible."

Pros: "Our attendents were clearly focused on our needs. Efficient and still very human and kind. A real treat."

Cons: "Missed connection along with about 25 others due to the delay getting to Lisbon (no reasons given)."

Pros: "Good flight good staff. Captain explained the route which is nice."
Cons: "No negatives"

Pros: "COMFORT AND ENTERTAINMENT WAS BEST"
Cons: "BOARDING SLOW CREW A BIT RUDE"

Cons: "A kid next to me keep shifting and kick me and nudge me all the time. His dad was trying to stop him from moving too much but couldn't control entirely. I kept waking up"

Pros: "The plane stewardesses were actually really efficient (German style). Because of being on the waiting list to get on the plane I couldn't get a seat next to my partner so they did the biggest math exercise to put us together. Props to them"
Cons: "The flight overbooked (I still don't understand this concept, since is basically selling twice the same seat, right? Is that even legal?) Also the system was down, so no check-in online = the biggest line at the airport, it took me more than 1 hour to check-in and drop my luggage, all to get there and the ground force lady (the rudest person alive) tell me that I had no seat available, that she was going to put me on the waiting list... WHAT? I bought my ticket already, waiting list? Well, to say that I highly doubt that I'll book with Lufthansa again."

Pros: "Lufhansa did a great job. During flights, everything was good."
Cons: "Security check in Frankfurt was terrible, violating all human rights in every possible way! Please don't tell me that it is for passengers safety; such a humiliation cannot be justified by any reason! Since Lufthansa uses this airport for the most of their flights, I would not fly with this company anymore"

Cons: "We were told by the Delta baggage handler that they strike one day each quarter. This would have been helpful information before we booked our flight from Kayak. We had to delay our honeymoon by 12 hours and fly into a different airport. Delta was great though and the Luthanza agent who rescheduled us was also great."

Pros: "Lots of carry on space"
Cons: "I expect cabin crew to assist me with my luggage. They were telling me to do it myself"

Pros: "Check in smooth and professional. Please change places with Asia air so you are in front of rather than behind the hoard of people."
Cons: "On my flight from Seattle to Frankfurt I had one stewardess repeatedly skip me. She was a bit older. I thought after the first overlook she would take extra care but did not. This resulted in me having to ask the crew to repeat their previous steps just for me. "Hi, I know you are serving coffee but I wanted red wine". She was a bit clipped about having to repeat steps but what was I to do? She never looked up enough to see my hand and clearly didn't look at my face. She also didn't pick up my hand towel. I essentially had to rely on the rest of the crew but the care from this lady started to feel purposefully negligent of me. The rest of the staff was friendly and efficient. I also thought we were supposed to get an appertiff...one was never offered. Couldn't check in online. Was fine once I got to the countr but could you trade space with Asia air? It makes sense to have them at the end as they have a huge hoard of people it would be nice not to have to go through and several spots to check in. Check in at the desk otherwise was smooth and professional."

Cons: "Friendlier crews"

Pros: "Comfort"
Cons: "Internet"

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

Pros: "Nothing"
Cons: "Transavia does not serve anything complementary, not even water. A flight between two countries that is five hours long must be better than this. I was not aware of Transavia doing that before I booked. I will never fly with them again"

Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."

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: "The crew was informative"
Cons: "Inflight sandwiches"

Cons: "Flight got cancelled"

Cons: "The KLM crew are always great serving and treating you. Well above many other airlines."

Pros: "Crew was great and helpful despite oversight in my special meal."
Cons: "Special meal request was overlook. I did not mind so much as eating less does some good! It is human to err!"

Pros: "Food and service"
Cons: "Working wifi would be good. Better A/C. More comfortable seats"

Pros: "Seat was uncomfortable. There was nothing to like. In past I have traveled by KLM but this time it was worst."
Cons: "No proper food service. Even to the passenger of Amsterdam no dinner was served. No inflight service. It looks like domestic flight. I will think twice to travel by KLM. The check-in staff at counter was absolutely arrogant. Staff ar boarding gate was nice."

Pros: "Friendly crew"
Cons: "KLM lost one piece of my luggage"

Pros: "Everything was smooth and effortless."
Cons: "Can’t think of anything."

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

Pros: "The crew"
Cons: "Seat comfort"

Pros: "Awful"
Cons: "Everything"

Pros: "Nothing"
Cons: "They check for everything in the counter as if it was a low cost airline. If you go a kilo more over your baggage allowance you have to pay 100 eur. And for your cabin luggage you only have 12 kg that they check you twice and they have security staff at the airport specifically check in this."

Cons: "The overall travel was good, no wifi and the entertainment system had a faulty headphone connection, and no place to charge devices other than through a USB port"

Pros: "Service was great as usual. Food was very good and entertainment options were great so you won't have to be bored throughout the trip."

Pros: "The flight AMS to MEX was smooth, very helpful personnel on board, we enjoyed a bit more space and the seat seemed a bit more comfortable."
Cons: "Besides the seat relative comfort, it did not recline much at all, i wondered what the extra money (at least $5 or $600) got us. The food, wine/ beer service was same as regular economy, the boarding took place at same time as economy, no drink before take-off if only sparkling water. And the plane was old generation 747 and the entertainment was same vintage: screen was not very bright and the selection of films was poor. No plug to charge electronics. We were disappointed with KLM when comparing with other airline companies offerings when you book in Premium Economy."

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: "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: "The staff tried to help me when it was evident we would not arrive on time"
Cons: "The connecting flight is too short of a time. We were late out of LAX and I missed my connection and had to sit in airport for 5 hours. Missed my grandson’s third birthday party. Just made me sad as Travelled from far to try to make it."

Pros: "I bought the Airport tickets for my Russian friend. However customs would not allow her to board the plane unfortunately. That's not Kayaks fault. I would definitely book with Kayak again. Many thanks."

Cons: "Flight was cancelled."

Pros: "The leg room, was surprisingly roomy"
Cons: "The food and that there was no entertainment."

Pros: "Friendly attendants. Decent food, and frequent snacks and beverages."
Cons: "No charging ports for electronic devices."

Pros: "crew were absolutely delightful, full of smiles and doing everything to make you comfortable. seats were fine enough and got some work done and a bit of sleep. first lunch was fresh and tasty, but the second, a burger, was edible, but not much more."
Cons: "tv screens are dated so movies are not as crisp as you find in newer planes. you need a 2 prong audio adapter to use your own headphones."

Pros: "The flight crew was nice. Plane departed/arrived on time."
Cons: "I paid €60 extra to sit in the emergency door seat to get more leg room but once.i was in the plane learned for more leg room I accepted a smaller seat next to a bathroom and no entertainment. I could not store my belongings near me. No power outlet to charge my devices for my own entertainment on a 7 hour flight. Dealing with constant traffic for the bathroom. I sat in the middle seat between two hours other men. It was a constant struggle arm space. After 7hours in the air I could not wait to get off the plane. If I didn't actually pay an extra €60 for the seat I may not feel bad but I feel like I might have been better off without paying for the "upgrade""

Pros: "Consistently high standards"
Cons: "Nothing"

Pros: "The food was excelent"
Cons: "I have to pay to pay a little more confort"

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

Pros: "The flight was great."

Pros: "Cabin Crew was awesome."
Cons: "Entertainment System was not working and no Non-veg food option in flight."

Pros: "Good multi media access and content"

Pros: "From downloading the KLM app to the final touchdown of my final flight, everything was an ease, checking in, the option to change my seat, the service received was great."
Cons: "The ability to state a seat or meal preference within the app would be good but otherwise all was good."

Cons: "suitcase didn't turn up, although connection was quite tight"

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."

Cons: "Not only was there free food but they tried to sell you a bunch of stuff. Not a moments piece."

Pros: "Speed, crew, and reliablity."
Cons: "Food wasn't good, no entertainment or accessory plug ins, and seats were worn out! Not comfortable at all. Great leg room though."

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: "Good and plenty of food available."
Cons: "No power to charge phones, laptops, etc and no WiFi available. For such a long trip (10 hours) below industry standard."

Pros: "The crew was very nice and helpful."
Cons: "The space is no longer a respectful space. Paid 32 Euros for my seat, there was not enough space, the man beside me kept jabbing me on the ribs."

Pros: "We really liked the KLM people, from the check in crew to the flight attendants."

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: "I missed my flight because of MU"

Cons: "sardines!"

Pros: "KLM food and service are great"

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!"

"Kayak was terrible, I was told that I got 1 free checked bag, but when I got to the check-in counter I was told otherwise and had to pay for my checked bag!!!!"

Pros: "Great crew, on time, could get a good nights sleep"

Cons: "I didn't like putting two family on different seats far from each other"

Pros: "Nothing"
Cons: "Customer service"

Pros: "At least the crew was friendly"
Cons: "The flight was delayed for 1 hour and we were sitting inside the airbus with no air condition due to technical difficulties on 35 degrees sweating like pigs. No water or snack was offered even though the delay was so big."

Pros: "I got to my destination"
Cons: "Endless waiting and lost luggage. Excuse was unpredicted weather conditions. It was snowing in Finland so they had to clear the Ice from the planes.. Snowing in Finland? How uncommon is that during December? I think most of this is poor ground handling In Helsinki."

Pros: "I got there"
Cons: "Endless waiting and lost luggage. Excuse was unpredicted weather conditions. It was snowing in Finland so they had to clear the Ice from the planes.. Snowing in Finland? How uncommon is that during December? I actually think most of this is poor ground handling In Helsinki."

Pros: "Hi enjoy the trip"
Cons: "No complaints"

Pros: "Excellent"

Pros: "I really enjoyed the whole flight - Finnair is definitely one of the best airlines."
Cons: "I wish there was a bigger choice of classical music in the entertainment program."

Cons: "The plane landed much later than expected, and I missed my connecting flight to Moscow. While I was given another boarding pass, I had to have another layover in St. Petersburg, and fly to Moscow from there. The flight turned out to be much longer, and much more exhausting. My overall experience was unpleasant."

Cons: "Late takeoff caused me to miss connecting flight from helsinki to Tallinn"

Cons: "N/a"

Pros: "I like the crew, the new aircraft, the airport in Helsinki, the business lounge in the airport"
Cons: "There was nothing that I truly disliked. I thought the food was mediocre and the business seat rather lumpy"

Pros: "The flight was good! Much better than US domestic carriers with comfortable seats and a good layout to the aircraft."
Cons: "Food was good, not great. Crew was attentive but missed being great by one notch and the flight could have been faster. All trifling details. But overall... If they didn't run out of chicken on the flight"

Pros: "Airplane was nice."
Cons: "I paid $90 for economy comfort for my flight and did not get an economy comfort seat. I am very disappointed with Finnair in this. They will not refund my money at the airport and now I need to go through their home office for a refund. It was bad enough not having any extra leg room on a red eye when you are over 6 feet tall but now I have to jump through hoops to get my money back."

Cons: "I could not be given the boarding pass fir the last leg of my trip"

Pros: "The general entertainment/informative systems ran perfectly smooth without hiccups! Cabin crews were all pleasant to everyone onboard and I didn't feel as tiring after my 10.5 hours flying time as compared with other airlines!"
Cons: "The pre-booked in-flight WIFI service can hardly say it's working as the connection speed was way too slow to perform any general tasks and that's ashamed as I paid premium charges for that and didn't expect that I couldn't use the service at last"

Pros: "In JFK the Finnair staff helped us expedite our connection process (the flight from Helsinki was delayed and we hardly had time to make the connection)."
Cons: "The flight was delayed by almost 4 hours. It was a miracle we made our connection in JFK."

Pros: "Finnair is great when nothing goes wrong..."
Cons: "... but a disaster when things go wrong. Too many pilots "sick" on new year day so our HEL-SIN flight was cancelled. We spent three hours at the airport queueing and only getting a hotel. No alternative flight. We spent an hour waiting on line at their call center (no local numbers, only one Finland number) and got rebooked on a super tight HEL-FRA-LHR-SIN connectiob, which we barely made as the connection times were so short. Plus they messed up the checkin so we got denied boarding in Frankfurt and lost our suitcases. Perfect storm... we will NEVER take this airline again. Totally understaffed and I competent. Fly a major airline and pay a little more to avoid things like this..."

Cons: "They lost my luggage at some point in the short journey."

Cons: "business class was empty and not able to upgrade at an affordable price"

Pros: "On time , excellent service"

Pros: "One cool things is that some of the moveis were translated with several different languages in addition to English and Europearn languages."
Cons: "Distance between the seats are short and seats are somehow uncomfortable."

Pros: "crew, food"
Cons: "Sat in row 53 of 55 rows, should have boarded in sections instead of everyone all at once. Could not sleep due to passenger behind kept jostling my backrest."

Pros: "Food was provided when the flight was delayed for 2 1/2 hours. I also really liked the text update from kayak about the delay. The airline did not keep me updated but kayak did."
Cons: "The delay when it was already a 6 hour flight. I also was not able to reserve a seat because I had booked through kayak and not with the airline. Finally of the most irritating of all annoyance was that there was no movie. This was an international flight and there was no entertainment. I will never fly American Airlines again."

Pros: "They moved my boyfriend and I from the back two seats on the plane up to the front with four seats across the middle! This was amazing for the long flight and allowed us to be very comfortable throughout the flight. Great service as well with three food servings and constant trash pickup."
Cons: "Woman in front talked endlessly"

Pros: "Not much to enjoy"
Cons: "The service. 3 hour late flight, had to rebook my connection out of my own pocket. After we got on the plane, we find out the issues were not fixed and had to wait another hour. Terrible food. Yogurt was actually expired, so I had no breakfast. People were all nice as they told me I should have booked the flights together. Hmmm... Maybe you should not have been 4 hours late. I planned my trip with more than enough time to make connection... Called about my travel insurance and found out it kicked in after 6 hour delay. Customer service should never make you feel like the issue is your fault."

Pros: "I had an empty seat beside me on both legs of my flight. This always makes flying more enjoyable. They fed us two meals both directions. There were pillows and blankets for everyone on your seat when you arrived."

Pros: "The service were very good. Just wish the food better selection."
Cons: "The leg room were tight."

Pros: "Very pleasant crew!"

Cons: "I missed my flight from Chicago to Paris. Because I purchased it through Kayak instead of directly through Finnair or American Airlines, their 'hands were tied' and they could not reroute nor reschedule me. Not only that, but because I was not on the flight to Paris, my returning flights were automatically cancelled. While this is probably included in the fine print etc., I find it ridiculous. There should be a better alternative for people who miss their flights than forcing them to pay a lump sum that is higher than the original ticket price in order to reschedule their ticket. Moral of the story: BE VERY CAREFUL WHEN YOU BUY THROUGH KAYAK OR SIMILAR AGENCIES, BECAUSE THE CUSTOMER SERVICE IS ATROCIOUS."

Pros: "I did get to move away from complaining passengers but "lost my coat" in the process. People are awful and obnoxious"
Cons: "Who doesn't turn off the plane lights at night inside the cabin? Especially when you're feeling late at night? Didn't post gate until very last minute…LHR..Then it said boarding immediately. Nowhere to get water. Hurriedly Boarded plane to find out we have the sit there an hour. Girl next to me was so childish Loud mouth complaining because she couldn't sit next to her bf."

Pros: "the price was very good"

Cons: "Seats given away that we selected six months ago even though we checked in days early. Four family members all over plane."

Cons: "Experienced very rude cabin crew"

Pros: "Called BA (the carrier for our FinnAir flight) when I couldn't check in (didn't have a booking number that worked). Staff member did tell me that all was in order with our booking. He wasn't able to check us in anyway, as something was amiss with 'the system'. In the end all worked out fine, we just made sure to get to the airport early to make sure we got decent seats."
Cons: "A bit nerve wracking to see online that our flight information 'could not be found' when trying to check in with the booking numbers I had!"

Pros: "Movies Food Comfortable seating"
Cons: "Going through security"

Pros: "Nice dinner, drinks, and snack services"
Cons: "Could be a little friendlier. Lights on the whole time during a red eye was pretty annoying. Don't know if this was on purpose or a malfunction. Entertainment system was hard to see and a little outdated."

Pros: "Power in every seat. Great headphones. Solid in-flight entertainment."

Cons: "No leg room"

Pros: "The energy of the crew was upbeat despite the lock of enertainment they tried their best by accommodating my various wishes."
Cons: "They were no snacks available except the ones that we had to pay for - which in fact I thought was a bit pretentious towards the passengers."

Pros: "Nice flight, plane was new so that was great. I was traveling alone and got upgraded to Premium Economy. Lovely!"

Pros: "Once we got on the flight it was all good!"
Cons: "We had the worst experience getting to our flight this airport is so badly managed it is laughable."

Cons: "For an international flight I have never seen such small seats, the entertainment was awful. My tv was in black and white. I didn't even want to try the food as looked bad."

Pros: "Other than the fact that it's a direct flight from jfk to Helsinki, there's not much else to like about it"
Cons: "Even though we paid extra for comfort seats, the seats were extremely uncomfortable! Not just the lack of sufficient leg room (especially when the person in front reclined) but most importantly the quality of the cushions. They were like cardboard and extremely uncomfortable to sit on. We were not able to sleep at all due to the discomfort! Additionally, they lost my luggage. It has been more than 24 hrs since I landed and I still haven't heard anything from them as to where my luggage was, when I should expect it why it still hasn't been delivered. Overall, a terrible experience."

Pros: "Nice one"
Cons: "Nice one"

Pros: "Great service. Comfy seats."

Cons: "We waited for 3 1/2 hours in the plane before taking off. We ended up landing with a 3-hour delay."

Cons: "Nothing was dairy free, staff did not even have access to ingredients so I could check myself."

"The cabin crew was friendly. But boarding takes forever and the flight gad long delays on both inbound and outbound flight"

Pros: "How great everyone was and smooth sailing."
Cons: "Made sure the flight was not over booked."

Pros: "Na"
Cons: "They have a terrible communication problem, they never communicated why the flight was late, they never communicated what they were doing or what was happening. Bad customer service. Bad communication with the client. They told us when I asked several times that we would not lose our connection and that everything was fine and that was not the case. We lost the connection. No one told us anything. Another problem was that the girl in the boarding process removed the suitcases tickets from the boarding pass and did not want to return them, and held it without any cause. The flight staff went looking for us. Pretty sad and disappointed by their service. I understand that they were causes outside the airline but must communicate to the client. They cannot remain silent and say nothing."

Pros: "The seats were spacious and the crew was wonderful. The crew actually made the long flight more tolerable. Will seek out Delta/Air France for further international flights."

Pros: "Nice and attentive crew."
Cons: "Seats not comfortable in premier economy."

Pros: "The crew was excellent and surprisingly the seats were comfortable."
Cons: "I think more attention should be paid to cleaning the plane and eeek, there was no liqueur in economy class. Music selection in entertainment should be wider too"

Pros: "I like the comfortable seats"
Cons: "Service lag a little"

Pros: "Boarding procedures and crew were top. Wines and beverages excellent and even in super economy water was served several times"
Cons: "The food could have been much better, should consider doing everything organic. As it was, the chicken in the meal was awful, the dessert terrible. The rice in the salad hard, almost uncooked. The only good quality food was the bread and the cheese"

Pros: "Crew was ok and servicial"
Cons: "Food and reception at door of boarding"

Pros: "The crew was amazing and extremely helpful!"
Cons: "The food could have been better"

Pros: "Excellent service"

Pros: "The crew was very helpful in all respects."
Cons: "Not getting everyone standing in line to board one hour and 10 minutes before scheduled departure."

Pros: "Good crew, as usual with Air France."
Cons: "Old plane with very lousy seats for a super expensive business class. Super slow check in and overall process till boarding because of lack of ground staff compared to passenger volumes"

Pros: "On time, no hassle."

Cons: "Too much time spent at boarding. On luggage missing."

Pros: "Crew was amazing. Service and food was good."
Cons: "Random TSA check was not needed at the end when boarding."

Cons: "Great experience"

Cons: "Two hour delay meant we missed our connection. Then given a very late flight and had to haggle for ages to get earlier flight and told we should pay extra for it!"

Pros: "Crew members"
Cons: "Up to 1 hour late and they leaved my baggage in Paris"

Pros: "The staff..the attentions..food."

Cons: "Flying back to US, passsengers get charged for their luggage. Which this is not informed to us, neither On our email nor when we were checking ( for free) in Us"

Cons: "My entire travel experience became extremely rushed and chaotic due to my flight being canceled and me being alerted -LESS THAN AN HOUR BEFORE IT TOOK OFF! This is unacceptable."

Pros: "Great service"

Pros: "The food, beverages and choices of movies, entertainment There was a medical emergency that caused the flight to land in Canada. This was handled very professionally - I hope the passenger ended up getting the care needed and is doing well."

Pros: "Modern aircraft with power, big screens etc"
Cons: "Teenage crew, poor service (not even water brought on request, all "self service" at back of flight, and not being allowed a second drink with dinner), poor language skills (crew not very helpful when 2 hour delay meant I could miss connecting flight, suggesting I "walk fast")."

Pros: "Staff"
Cons: "We were 2h late"

Cons: "We paid for Business Class from JFK to TLV. The flight to Tel Aviv was in a small plane with 3 across seats that hardly reclined. We are most unhappy and will complain to American Express Platinum Card."

Pros: "The service was very professional."
Cons: "Everything went well."

Pros: "Nithing"
Cons: "They were unfreindly and rude."

Pros: "The friendliness and courtesy of the staff."
Cons: "One piece of my luggage was left behind in Paris."

Pros: "great seat, good food and drink, pleasant staff, efficient boarding and exit."
Cons: "no complaints"

Pros: "The food, the service and everything else is fine, quite good."
Cons: "However, our baggages were 1 day late. Your missing baggages would deliver to you 1 day later, for some maybe 2 days later...Quite a few people said that it's been always like this with air Aeroflot if there is a transfer flight."

Pros: "Crew was friendly and professional, fresh croissant and hot chocolate on my short flight. As many airlines charge now for any and all food items it was nice to again experience fast and efficient food and beverage service without the tedious hassle of ordering and paying. I’d gladly fly Air France again. First time, but likely not the last."
Cons: "Like all airlines , the seats could use a few more inches of space, even two would be nice."

Pros: "Friendly staff"
Cons: "Window pane was broken on my side and I couldn't shut it down. As it was a day flight the sun heated my skin badly"

Cons: "Not checking my carry on weight at check in then letting me walk all the way to security to then check my bag and tell me to go back to check in then the counter is closed and they tell me it's too late and that I need to get ride of my things so that my bag is under weight and barely making the flight"

Pros: "Short & easy flight"
Cons: "All ok"

Pros: "Got pillow, blanket, headphone and eye cover"
Cons: "Older plane Very small tv screen Didn't get the bread roll with my dinner. Asked for it but she didn't bring it to me. No usb plug to charge"

Pros: "Friendly onboard staff"
Cons: "Treated like cattle while boarding unless your preferred member. Average food quality."

Pros: "Pretty decent"
Cons: "Not much"

Pros: "the Airline"
Cons: "The Airport, Security, Boarder control."

Pros: "1) USB charger and electric outlet 2) Availability of 2-across economy seats (for a price) 3) Vegetarian dinner option available and not too bad 4) Flight arrived on-time"
Cons: "1) Front seat pocket bulging with 2 extra-thick in-flight magazines 2) No on-board wifi 3) Not much seating room - very thin"

Pros: "Great crew"
Cons: "Food could be a bit better. White bread is unhealthy."

Pros: "Staff was responsive, effective and pleasant; Nice selection of digestifs too. Food was decent and, in airline level, even good."
Cons: "The audio system is outdated with unreliable touch-screen that makes it frustrating to navigate."

Cons: "The leg-space is very narrow The chair is very tiring No entertainment at all Food was tasteless But most surprising was that we were on stand by for our connecting flight. Though we bought the tickets months ago and we got our luggage checked in all the way to the final destination."

Pros: "Nothing..worst experience ever. Simply apologising for delayed doesn't help"
Cons: "Flight into and out of indiapolis was delayed by 2 hours. Missed my connection flight to LHR because of the delay. never had such a flying experience. Flight was operated by Delta. I won't be flying them again."

Pros: "The boarding process was smooth and the crew friendly. Flight ran on time."
Cons: "Unloading the baggage took over 90 minutes, and there was no explanation for the delay and nobody from Air France in sight on the ground in Boston."

Pros: "Efficient check-in."
Cons: "It was raining in Prague so I can understand that luggage is going to get wet. But when we opened our luggage at least half of our clothes were wet. It would seem that the luggage sat out for quite a while prior to departure for that much soaking of clothes. Fortunately we are staying in Paris for a few days and can get our clothes dried out."

Pros: "Boeing 777 had a lot of space. Good legroom. Timely departure and arrival, hassle free, safe trip all the way. Enjoyed the red wine; very delicious!"
Cons: "Seat didn't recline. The entertainment unit was very difficult to dislodge and raise to use (We were in the front). Movies were kind of older ones but I had reading to do so entertainment wasn't that important."

Cons: "Flight was delayed by 1 hour 30 minutes. After over 24 hours of travel this was not appreciated. Also no lounge access at Toronto airport."

Pros: "Efficient boarding. Interesting hot food. Entertainment variety very good."
Cons: "Business class seats hard. Did not flatten out for sleep."
