The ticket agent, the gate agent and the cabin crew all did nothing to make up for the fact that their system screwed up and stuck me in a cramped coach seat in the back of the plane for 11 hours-- TWICE! Beyond that, KLM must have one of the oldest fleets in the sky. Both ways LAX->AMS->LAX, I was on a 30-35 year old 747 with no wifi, no power and a ten-year-old entertainment system. Never again."

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

Pros: "Crew was very helpful.food"
Cons: "Food was not upto the mark."

Cons: "Flight delayed by one hour which meant I missed by train at Southampton by 10 minutes and subsequent bus connect home. Next bus would have been 2 hours later so 45 minute walk home from train station. Didn't bother with food offering, put off by that supplied from Hannover to Schiphol."

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

Cons: "Kosher food could be improved"

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."

Cons: "With skyteam elite status cannot select free upgrade from economy to premium economy unless it is 30hrs before boarding for this code share which is actually a KLM flight"

Cons: "Nothing​"

Cons: "video was broken"

Cons: "Paid economy comfort and did not allowed me to board on group 2 as advertised, eorst entertainment system i’ve seen in a long time, aparently the experience is totally different if you fly A350, Jfk-HEL fly the A330"

Cons: "Sat on tarmac for 2 hrs, told we would get a snack then they changed their minds"

Pros: "leg room, service, movie selection"
Cons: "the arm rests don't go up, the food was weird. It's nice that they served two meals but both of my vegetarian option meals were cold and unidentifiable."

Pros: "The flight was good. Enough legroom for me, the food was ok. And the crew was pleasant and attentive."

Pros: "Liked this flight had exit row with lots of leg room for my 6'6' husband. As we requested"

Cons: "Food, no option asked just served from Helsinki to Miami. Entertainment system was not working and later had only limited options."

Pros: "It is misleading to review this as finnair flight. Not relevant"

Pros: "Good movie selection, frequent water refills, boarding was quick and easy with ample overhead stowage"
Cons: "Seat recline was broken, non-adjustable headrest, older flight crew less tolerant of passenger disrespect, not quite enough bathrooms, food had my stomach in knots"

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: "Pleasant staff and crew."
Cons: "Tv screens are old and function very poorly."

Pros: "The crew did an excellent job definitely went beyond good service, I enjoyed the food and they came often offering drinks. It was probabky my first long flight I wasn't thirsty at all. Overall I was very happy with my trip hope thank you!"
Cons: "I got slightly cold at one point and wished the lights were I little lower but I understand why the weren't."

Pros: "Friendly staff"
Cons: "The entertainment system is terribly slow and hard to work with, food was awful. Next time I will bring my own."

Pros: "great flight. a little cofusingto get the right airline"

Pros: "There was a flight attendant who was perfect for his career-absolutely the best ever on the Rome to Philadelphia flight-a tall, African American gentleman. So accommodating and friendly!"

Pros: "The fact the plane didn't crash"
Cons: "Couldn't check in online- extremely slow at counters to get my checked bags, forced a meal of curry since I was in back of plane and there were no more 'non-vegan meals'- smelled NASTY! Ignored a lot by attendants bc rushed to get to back of plane attendant area and chat. Tv could barely be seen from window and then volume/distortion was awful while flying. The attendants were gaga about a screaming baby but ignored the rest of us"

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

Cons: "I paid for an upgraded seat and after boarding other passengers were being moved to the same area that I had paid for an upgraded seat FOR FREE!"

Pros: "Good service...."

Pros: "I flew with American to London and with British in the way back... British air is such a nicer experience from the food, to the crew, to the entertainment."

Pros: "The flight attendant ruined my trip and experience3 with this airline."
Cons: "Twice I was passed up and overlooked for food and drink when they were being provided to all. The attendant said i needed to speak up if i wanted something and i pointed out i did and he said he would get me on the way back but never came back until he was picking up the empties. He said everyone else seemed to get served what was my problem and I pointed out the girl next to me was also skipped to which he turned around and never walked down my aisle again. Also, the lack of wiFi on this leg was a disappointment as it was available on the trip to Barcelona. That goes a long way to making the long trip more enjoyable."

Pros: "crew was friendly and courteous"
Cons: "had to be bussed to different part of airport to board plane no sound on the entertainment console"

Pros: "The fact that I got home in one piece I really like."
Cons: "Planes are old, small tv screens in aisles, older seats and headrests. I had requested Gluten Free meals and on the way to Amsterdam they did okay (besides the snacks). On the way back they didn't even offer me the second meal GF, I had to ask another flight attendant who went looking for it and found one.. so it was there, they just hadn't bothered to look for it. I also never understand why you wouldn't start boarding with the last rows? Is that just me? The aisles are always so crowded when the last rows walk in and there's always a line."

Pros: "Crewmembers were professional and nice!"
Cons: "Snack and meal were not so tasty, and the descending before landing was really uncomfortable."

Pros: "Good service, on time, friendly and helpful flight attendants."

Pros: "Departed on time and arrived early. What more could you ask for?!"

Pros: "Seemed to be a little more leg room than usual. Crew was courteous and efficient. It was an American Airlines trans-Atlantic flight that arrived early. Overall a good flight."
Cons: "The response of the American Airlines entertainment system is as slow as pond water, although the choice of entertainment was very good."

Pros: "The more modern plane with USB ports that actually charge and the higher quality and bigger displays really help make the trip more enjoyable."
Cons: "Not as much to eat on this BA flight back to Philidelphia from Hethrow as there was on the American Airlines flight there."

Cons: "The plane was old. The movies were played in the aisle and the selection was inappropriate/terrible. No kids on the flight and they played a Disney dinosaur movie and the Peanuts movie."

Pros: "The plane was not full"
Cons: "I wish it truly were Finnair instead of American: The seat, the legroom, the fact that you have to pay 20% more to have the same rotten seat 12 rows further up front, the food that's barely fit for human consumption, the presence of 20 year old cathode screens that can't be watched but do prevent the cabin being dark, etc."

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."

Pros: "Friendly flight crew made me feel very welcome . Food and drinks service was excellent, nice choices. Movie selection was vast."

Pros: "I was not well and at the check in the lady was kind to change my seat ..."
Cons: "I order a special meal ....no meal for me on the plan ."

Cons: "The flight attendants blocked off the last three rows of seats and laid down and went to sleep!"

Pros: "Flight operated by BA; food was excellent, wine was free, crew were friendly."
Cons: "Legroom so cramped its dangerous; worse than on my CRJ connecting flight."

Pros: "Great service. Comfy seats."

Cons: "The food was terrible , the flight was canceled from Paris to phila , i didn't know til 8 pm . It was very hard to have an other flight from London to phila. A lot of souffering for me ."

Pros: "Courtesy of attendants, smooth flight, good service"
Cons: "Food and your TV screens are not good. Very hard to operate a touch system which is so insensitive. Movie choice rather poor as well"

Pros: "Very friendly staff, smooth ride and information provided"

Pros: "This was actually a USAirways flight now rebranded as American. A lot of people had to check baggage. There was no in-seat video entertainment. The crew were surly."

Pros: "About the only positive was that the plane left on time and arrived on time."
Cons: "Checking luggage was a nightmare. I stood well over an hour in line. We barely made the flight, and afterwards our luggage was lost, and it still has not been found. The wheelchair that I had ordered for my travelling companion was not there, either at Manchester or Philadelphia. The seats that I had reserved were given away to someone else. Whilst the plane flight itself was okay, the airport experiences on either end were miserable."

Pros: "The service is great , I enjoyed the food as well. Attendants were very friendly."
Cons: "When flying from US to Erupoe there should be a private tv screen directly in front of every passenger. On this flight the tv is in the middle of the isle on the ceiling. That's terrible ! When you are on a 8 + hour flight. People want their own screen with their own options. Been on many flights to and from Eruope , this was the only flight that was set up like this. Change it"

Cons: "The headphone socket didn't work, the screen was tiny, the food was bordering on the inedible, the seating was cramped and uncomfortable, the air was dirty and unhealthy."

Pros: "The crew was very helpful and the entertainment was updated."
Cons: "Philadelphia airport services were terrible: - immigration processing was too long and took more than one hour dur to out of service customs machines and insufficient immigration personnel. - luggage handling at the airport careless and resulted in the breaking of some of my belongings."

Pros: "I was running late getting through check-in because there was an abandoned backpack that caused a huge mob scene and delay. The American Airlines/(Finnair) check-in staff were WONDERFUL and made it all OK, pulling us out of the mob to get us through check-in. Then I went through security, which the check-in staff had tried to expedite, and got stopped for a random inspection. Then, after boarding passes were scanned, I was again stopped for a random search that took apart every zippered corner of my purse and my carry-on bag. But again, everyone was lovely to deal with. By the time I got on the plane I was grateful for having caught the flight, and for the kindness of the Paris staff, and marveling at what an obstacle course it had been. And I had enough leg room."
Cons: "1. The sound on my in-flight screen did not transmit the movie sounds, so I read a book all the way back. 2. The red wine was great to have. The food was like school cafeteria food, so I ate what I had brought with me. 3. The seats on airplanes never fit my body right. I sit very straight and upright, and I'm fairly tall. The airplane seats keep forcing my head forward and my back into a hunch."

Pros: "everything except food"
Cons: "food"

Cons: "A bit confusing and not sufficiently emphasized and explained. There were two sets of record finders, two sets of billing. For a while, I was wondering if I was double billed."

Cons: "One crew member was extremely curt to myself and fellow passengers, not telling us to put down viewer, just slamming it away. Could have said something, been pleasant."

Cons: "I was"

Cons: "Last plan of the day waits for all transit passengers! Never take the last plan out of SAS hubs anywhere if you want to avoid delays..."

Pros: "At når det bar noe som var mistenkelig så var det ikke noe alternativ, skift fly"
Cons: "Å måtte skifte fly"

Pros: "On Time, Friendly,well maintained equipment"

Pros: "Friendly staff"

Cons: "Not enough characters to express my disappointment."

Pros: "price, water, easy boarding, in time"
Cons: "noise, no snacks"

Pros: "The airline staff were so positive and friendly. Really made the long trip easier."

Pros: "My Plus ticket brought me an excellent cold lunch despite the shortness of the flying time (only 1:10). The seats need more recline!"

Pros: "Pleased with everything."

Pros: "Real meals"

Pros: "Super"

Cons: "Seat was uncomfortable."

Pros: "Had to pay USD 75/bag which was not clear when I booked the ticket. You have to inform the customer about these rukes."

Cons: "Small, uncomfortable seats which is tough for a long fight."

Pros: "boarding is different and they were talking over pa announcements at heathrow so you could not hear what to do. you go through one ticket agent to the down stairs to another ticket agent. everyone knowing what to expect crowded around the second ticket agent and there because of that forget about boarding by row or zone you couldn't get throught the crowd. plus the second ticket agent was right next to the downstairs escalator so people coming late got on before us."

Cons: "to realise at the airport that they will charge me 70 EUR for one luggage for one way only is outrageous! it wasnt clear at all that there wasnt luggage included in the price of the ticket... all of my previous tickets bought via kayak and priceline were also with luggage included and we have understood the given price as including luggage! i find it very negative and very bad experience and feel robbed, this is not acceptable business approach. my suggestion is that you will refund me the extra cost for the luggage. thank you."

Pros: "Too upset to continue senseless survey"
Cons: "Vacation ruined"

Pros: "Much roomier than united"

Pros: "Easy embarkation, helpful staff."
Cons: "Shock to discover that suitcases were not included in price of tickets purchased online. We had to pay the equivalent of $100 (australian) per case. My seat was extremely u comfortable as the cusihion was misshapen. The male passengers seated behind us were drinking alcohol and became loud and garrulous, making the trip most uncomfortable and unpleasant."

Pros: "Everything was smooth"

Pros: "Sear had great leg room."
