Cons: "crew at the gate."

Pros: "Service was excellent"
Cons: "Carry on baggage size misleading"

Pros: "Movies"
Cons: "Crew was rude to passengers. One passenger asked for extra bread and crew arrogantly commented , we dont give but ok take one."

Pros: "Coach seats were comfortable but if the person in front of you reclines, your video screen will be inches from your face and it becomes difficult to get out of your seat."
Cons: "Crew was not particularly friendly....almost downright rude at times"

Cons: "Only two options for dinner is very few options."

Cons: "The crew responsible for boarding did not provide timely information (especially on who boarding order) and "made up" for this lack of communication by yelling and screaming at passengers as if they were cattle."

Pros: "Again boarding was smooth"
Cons: "The seats were terrible"

Pros: "Boarding was smooth"
Cons: "The aircraft was horrible No space at all even after paying for a better seat"

Cons: "I’m a small person & your seating is cramped & uncomfortable!"

Pros: "Great airline overall!"
Cons: "No leg room due to the airplane box under the seat in front of me. Very difficult to straighten legs out, difficult to get comfortable."

Cons: "My special meal wasn’t available."

Pros: "good flight didn’t have any problems"

Cons: "Almost missed my third plane, too."

Pros: "Online check-in was easy, boarding was smooth, and time on the flight seemed to go by quickly. Seats were a little too close together in economy to fully relax but that's the nature of economy seating. The dinner was very tasty, crew was friendly."
Cons: "My seat-back entertainment system did not work, but I had not planned to use it anyway. For the other three members of my family it did work, but not very well. Fortunately they had other options they brought with them."

Pros: "Captain kept us informed regarding takeoff"
Cons: "Sitting too long"

Pros: "Fast flight and crew was amazing."
Cons: "Seats are terrible. Food is just ok, could me better, I remember 2012 when I was flying first time with Swiss (same route), food was excellent and seats were much more comfortable. I’m thinking to get back on Turkish Airlines although the trip is much longer, they are much better in both above mentioned segments."

Pros: "Excellent Service. Excellent food."

Pros: "The flight was perfect until we hit horrible turbulence. 1 out of every 4 people was throwing up. We had to redirect to Milan."
Cons: "Swiss air is completely inept at handling a very normal reroute due to weather. 200 displaced people are standing in line. I’ve been here 5 hours and have not heard a word of announcement from them, our questions are rudely thwarted, and they continue to take half-an-hour to an hour per person with uncertain results. Give use new flights or a hotel."

Pros: "I hope this carrier grows by leaps and bounds. The plane was new & clean, the pilots executed flawless takeoff & landing, the flight attendants were friendly to a fault, the plane left on time & arrived early. Round trip Orlando-Venice was $980 round trip. The only niggling detail was the somewhat limited selection of movies."

Pros: "I am a frequent flyer with swiss airline. Amazing crew, boarding, taking off and landing is on time if not a little earlier. However, I was quite disappointed with the enertainment package and food."
Cons: "I am a frequent flyer with swiss airline. Amazing crew, boarding, taking off and landing is on time if not a little earlier. However, I was quite disappointed with the enertainment package and food."

Pros: "very professional crew, clean cabin, interesting choice of documentaries"
Cons: "it would have been nice to see a hostess walk through with water every hour, of so why is there no world news in your tv selection?"

Cons: "Warm breakfast in coach would be appreciated, but i understand it is just coach."

Pros: "I like the space in business class and the staff were really nice"
Cons: "The seats were not comfortable, they ran out of scotch (single malt) and I only had 1 drink"

Pros: "Food, staff, service"
Cons: "No leg room"

Cons: "Airline lost my flight, no explanation and or apology. Seats were terrible could not move when seat in front was reclined. No economy plus, no reciprocal consideration for gold status on star alliance except for one checked bag free. I will never fly Swiss again"

Cons: "There was a supposed difficulty with my entry in Europe when I tried to Check into Chicago. I thought that I had to cancel my flight. Swiss air representatives had to do much consultation, which took nearly an hour, while I was standing there the whole time. At the end, I was thanked for my patience and told all should be well and not even given a small upgrade for the distress this caused me. Traveling is disagreeable in general now, and personally, even moreso after this episode."

Pros: "On time, efficient, good service, professional"

Cons: "They lost my bag and after 24 hours, still no word on whether it's been located."

Pros: "Very prompt and courteus"

Pros: "Flight attendants were perfect, sincere, and friendly. Great selection of free movies."
Cons: "I could not open my laptop and do any work once the person in front of me put their seat back. Big time bummer."

Cons: "Seats are too close together in coach, very cramped and uncomfortable if you are a tall or large person."

Pros: "Good entertainment"
Cons: "Couldn't control the airflow at your seat."

Cons: "My flight attendant was rude and condescending the entire flight. I don't appreciated being treated like a moron for asking someone to repeat a question."

Pros: "The flight crew were friendly and helpful. The food served on our flight to Zurich was delicious. We loved the big movie selection which helped pass the time."
Cons: "The leg room was terrible on this plane. If anyone reclined their seats, you were trapped and could barely get out of the row to get up or go to the bathroom. Boarding was a bit like herding cats and everyone was jammed up trying to get on without any orderly direction."

Pros: "crew"
Cons: "seat size and comfort. Had metal nox take good part of my footroom. small aisle. Food lousy."

Pros: "First time flying with swiss air, loved everything about this airline!!"

Cons: "By the time they got to me I only had one choice for the dinner meal. No restroom in the back of the plane so I got stuck waiting for the cart to come all the way down the aisle before I could go to use it."

Pros: "Flight boarding was quick and fast and food was great."
Cons: "Seats had no room and if someone in front reclined the tv was right in your face. Also what happen to having individual fans above. It was so hot I felt sick the whole way and when we pushed the call button no one came had to flag down an flight attendant walking by. We had to ask three more times to get the heat down. Overall it was okay."

Pros: "same"
Cons: "same"

Pros: "Everything else."
Cons: "The selection of movies was not impressive"

Pros: "I like"
Cons: "Good"

Pros: "Friendly staff. Clean planes."
Cons: "My boarding passes for the second legs of this trip were not available for printing to agents in either NY or Geneva. as a result, I was forced to leave security in Geneva for special assistance, adding time, inconvenience and worst of all stress to an already difficult trip. I will NOT consider buying another ticket in his manner due to this horrible experience."

Pros: "Empty middle seat; disinfectant wipes. I know these measures were implemented because of COVID but I wouldn’t mind having these last past the pandemic!"

Pros: "The crew was lovely and friendly, very pleasant to fly with."
Cons: "Not a fan that I was seated between 2 men I did not know which made me uncomfortable enough that I couldn't sleep at all during my red eye."

Pros: "The crew was great. The flight was on time."

Cons: "The Anchorage airport was FREEZING cold and it was August, maybe a little less AC IS IN ORDER"

Pros: "The crew was very friendly. The plane was very quiet (except for noisy crying babies)."
Cons: "Unless you can afford the higher priced "comfort class" or first class seats, the seating is very, very cramped on Delta's 757s. It's a good thing the flight was only 5+ hours (but that's not long enough to get any decent amount of sleep on this flight scheduled as a redeye)."

Pros: "The only thing I liked about the experience and flight was the Delta Sky Club"
Cons: "Everything"

Cons: "More leg room and seat width. I don’t like having other passengers pressed against me."

Pros: "Flight was smooth"
Cons: "More leg room"

Cons: "First class seats were too close together. It was very difficult to get out of you seat into the aisle. Food was not what it should have been for 1st class There was no wall between 1st class and coach giving little privacy when I worked my laptop. it was in direct view of the middle seat in coach"

Pros: "Entertainment and food and service were great."

Pros: "Can’t do anything about bad weather-we got through despite a weather delay. Crew was terrific."

Pros: "The plane was 2 hours late and I could not get home. Missed the connection to Greenville at 11:38. They told me there were no hotels in Atlanta and I would have to stay in the airport and then take the 8:55 am fight to Greenville. That took an hour in line and there was no help."
Cons: "The pilot was awesome. He flew as fast as he could to help anyone make their connection but it didn’t help. But I appreciate him trying. Just frustrated that being military I didn’t get to board earlier or that they didn’t help me find a way home"

Pros: "Having the whole center three seats to myself. The food and beverages were really good as well."
Cons: "Both flights were significantly late to depart. Also the WiFi on the transatlantic flight was out."

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

Pros: "Our flight attendant was excellent. Service with a smile."
Cons: "We almost missed the flight sitting right in front of the gate. No announcements could be heard in the gate area and when we asked, they said they were already removing our luggage, Very odd. Food was terrible! Choices were pasta and cold chicken salad. I had the pasta, which was bland ravioli in two bland sauces. I was surprised, because I had experienced better food on recent international flights."

Pros: "The crew at the airport was very courteous and helpful."
Cons: "No food; not even offered water; I asked a Delta employee about our seats and she was very unprofessional (mind you I'm traveling with kids and my boarding pass said that seats were to be assigned at the gate)."

Pros: "Nicest crew"

Cons: "Flight was cancelled"

Cons: "Courtesy, on time and good communication."

Pros: "It got me to SFO earlyish"
Cons: "Was told to go away and wait for name to appear on screen for seat assignment. Was seated apart from travel companion. Got to sit next to folks with questionable hygiene, seat broken. Seatbelt broken. Stuck in back of plane window seat and was supposed to be “happy”. I was brilliantly ignored by crew. Seat back entertainment broken snd flight crew never answered the call button. Got to watch bag handlers throw and drop luggage like true gorillas. Delta, this time you truely are the worst. Wont book you again."

Pros: "It was on time. Flight crew was courteous. Plenty of room and comfy seats. Good entrainment media"
Cons: "Wish it would've had more movie options"

Cons: "Long delay due to maintenance of oxygen masks issue. Why hadn't this been taken care of with preventive maintenance?"

Pros: "The Delta planes on both legs were comfortable and the crew very pleasant."
Cons: "The check in lines were chaotic and I had already checked in online. I just needed to drop off my baggage, so to save time due to my early flight I paid more for the curbside check-in."

Pros: "the majority of delta flights i've taken over the past few years have had huge issues - either long delays or cancellations. i won't be flying Delta again"

Pros: "Left reasonably on time, arrived a bit early, able to find overhead storage for my roll-on, even boarding in Zone 3"
Cons: "Very tightly packed; minimal comfort for the flight."

Cons: "1. Boarding order is not by seating making boarding very inefficient"

Pros: "GRU to ATL to LEX - all was fine. The plane from GRU to ATL was one of the nicer jets I have ridden in. The ratings above reflect my overall trip of going to Sao Paulo and returning to Lexington, even though the first part had to be re-booked on United."
Cons: "LEX to ATL to GRU did NOT happen because the LEX flights were delayed to the point of missing the ATL connection. While Delta re-booked me on United, my flight arrived 3 hours later than scheduled (so transportation plans had to change), my bag did not successfully move from the Delta flight to the United flight (and was thus delayed in getting to GRU) AND once the bag was received, 4 shirts had been stolen. While a delay/theft claim has been filed with United, this could all have been avoided if the Delta flights had been on time."

Cons: "After 600,000 miles of flying, this one was the worst. 5 hours on the tarmac for a 4 hour flight."

Pros: "The crew was nice"
Cons: "I didn't like the fact that I didn't get my luggage with me when I arrived to casablanca as I lived 4 hours away from the casablanca. I have to come back the next day to get my luggage. I was very mad about it.plus I noticed one of my luggage has been damaged so now I have to buy another one because I can t use it. It was disgusting."

Pros: "The flight crew was nice and polite. They served drinks and snacks in a timely manner while on the flight."
Cons: "Flight was scheduled to leave early, the plane arrived, but they couldn't turn the plane around fast enough. We left the gat late, then pilot said we would still be arriving half an hour early. We arrived about 45 minutes late, and that was a problem because our connecting flight was due to depart now in 15 minutes. Lightning forced the airport to shutdown, which was great, we had a chance to catch our flight, but we were stuck in the airplane, and we couldn't get to our gate until the all-clear. I know this is not Delta's fault, but they did arrive quite late on a flight that, according to them, would be early. They also never communicated to the other flight that there were several passengers catching that connection. So by the time we had ran to catch our connection they had closed the ramp. Lightning hit again, and they shutdown the airport once again, so the airplane was still at the gate for about an hour, and they did not allow the 20+ passengers to board that plane, which was right there. So frustrating. The only thing that saved it was that our new flight was the new airbus, and although it left an hour and a half later, the comfort level was phenomenal."

Pros: "The service"
Cons: "The "cheese" plate was kinda sad especially for the price"

Pros: "Free drinks"
Cons: "Corn nuts for snack. I'm allergic to corn. I get people want snacks on a flight and you can't make everyone happy. It was ok. I just said no to them."

Pros: "IT WAS A GOOD TRIP AND THANK YOU"
Cons: "EVERYONE ON THIS PART ON MY TRIP WAS FRIENDLY"

Pros: "Despite efforts of most airlines in America it seems like they can't get it together like the foreign ones. ..I've very recently flown vigrin, garuda, malindo, and Cathay and they are miles above in service and comfort."

Cons: "Website is very difficult to navigate and use."

Pros: "Service, Efficiency. Quality of the food compared to Quality of the food other Airlines. Extra room provided by premium economy."

I had been looking forward to catching up on some movies ( rarely have time for to or movies usually) was disappointed to have no working screen on such a long flight. Did appreciate the effort to supply a gluten free meal, unfortunately someone added whole wheat crackers ( luckily still in wrapper ). The boarding area was mixed with people trying to get to New Jersey at the next gate making it very crowded and confusing, people found themselves in the wrong line."

Cons: "Seat headrest flaps were broken"

Pros: "Comfortable seats,good movies,fast service"
Cons: "Everything was great nothing to don't like"

Cons: "Gluten free meal for breakfast was a turkey sandwich?? I would have preferred yogurt"

The food was wonderful. The service was wonderful. The flight left on time and arrived early. The seat was comfy. Really nice flight."
Cons: "Um, have to think. They could find a better ice cream? They should have turned on the outlets earlier so I could recharge my phone?"

Cons: "My luggage is mia(possibly munich). Have no clothes, no gifts to bring my family, and not questions answered the where and when ill get my luggage"

Pros: "The attendant who did help was fantastic! The ride was smooth."
Cons: "My 12 year-old had a screen that was not working and finally we got an attendant to help us out. But until then, I had attendants who were telling us to try things and then they'd leave and not come back to check up and follow through, which left us constantly trying to find someone...one time our call light was on for 20 minutes before anyone attended to us. In addition, the bathrooms were very dirty. The breakfast was a really bad muffin that I couldn't eat."

Pros: "Service and food were excellent."
Cons: "Every seat had headphones, but the plug didn't fit the available jack. If we hadn't brought our own earbuds it would have been 9 hours of silence."

Pros: "crew was helpful, seats comfortable, leg space good, entertainment good. a good flight without incident. boarding and getting off plane went smoothly."

Pros: "The choice of entertainment was wide ranged."
Cons: "It was a big plane, and I was sitting at the back. When they started to serve drinks and our meal, both times it took way over half an hour for them to get to us after they started to serve."

Pros: "I loved the food for the flight and the service, it's always a pleasure to travel with Lufthansa. Awesome entertaining opportunities."
Cons: "Nothing really"

Pros: "Lots of movies."

Pros: "Timely distribution of meals/drinks, uncommonly quick boarding and ... unboarding. I travel with a musical instrument and some airlines want to check it and some even insist on checking it, even though there is always plenty of room. This was a completely full flight and no one even mentioned the possibility of checking it; they put me in an early boarding line and put it in a closet. The way they handle this for myself and the other passenger with an instrument made our day, as well as making boarding smoother forbus and everyone else. Really excellent job on that!"
Cons: "Old televisions with somewhat limited entertainment options. Im tall and every seat in coach is too small for me, but thats the case on every flight ive been on."

Pros: "Pretty smooth flight"
Cons: "Entertainment options weren't great"

Pros: "Yes"
Cons: "Nothing. Flight was amazing"

Pros: "Crew is excellent, polite and personal!"
Cons: "Plane is super old and outdated. Comfort seat is not, comfortable, very tight. TV screen is not good quality, with the old controls on a handset. No touch, no 1/8 inch audio jack (it has the old 3 holes one). Wifi for streaming freezes every other second. Just make a face lift to the plane, everything else is good."

Pros: "Comfort"
Cons: "Wifi on klm"

Cons: "Keep the temperature at a more reasonable level. Blankets + two layers of clothing was definitely not enough."

Cons: "A little bit chaotic when they loaded two planes at the same time in a very tight space in Amsterdsm but this was most likey an airport soecific design issue and not a KLM issue. The flight was as good as can be expected fir an international flight. The staff was great"

Pros: "I was sorted on Row 3 and the drapes kept hitting the back of my head."
Cons: "Move the drapes a few more inches back."

Pros: "Great crew."

Pros: "Crew was very engaging and service was good."
Cons: "My seat was horrible. Right at the door, crammed, and no place to store my carry-on luggage."

Cons: "We were allowed to choose our seats from SFO to Amsterdam but not for the return flight. I like to be able to choise my seats when I book the flight. Choosing seats 24 hours before is not convenient when traveling for the return trip."

Cons: "Lost a single baggage item, a car seat. Critical for us to leave the airport, and delayed us for over an hour upon arrival. Gave us a loaner car seat that barely fit our child."

Pros: "Being fed was amazing and watching free TV was great!"
Cons: "I wish there were personal fans because it got uncomfortably hot sandwiched between people"

Pros: "KLM was a great experience compared to Airitalia. The food was good, the flight attendants were very helpful."

Pros: "My seat at the window was great and the staff really friendly and courteous!"

Pros: "Good food, friendly service"
Cons: "More trash pickup; only one round of beverage service"

Cons: "Turn the lights on early making it hard to sleep"

Pros: "Last year I flew Lufthansa which was my worst experience flying ever. I thought the new standard was so low I would never fly to Europe again. I had heard KLM was good but I felt this was as good as could be expected actually much better. The food was even good."
Cons: "I would have to dream something up."

Cons: "Poor food, flight attend and finally baggage missing. Overall experience is extremely bad."

Cons: "wasn't able to take the flight since I missed it"

Pros: "Amsterdam airport and Rome airport were as breeze to navigate, even only knowing English"

Pros: "Flying with KLM is a pleasure"

Pros: "The food rocks! I know that I will always be eating well with KLM. The staff is always so nice, professional and cordial...I always know I'll be in good hands with the flight. KLM #605 from Amsterdam to SFO---please pass the praise to all of them."

Pros: "The seats seemed to have more space on this plane which was nice."
Cons: "It felt strange that the crew members completely skipped over me when serving lunch and drinks. At least something as basic as water should be given to all passengers."

Pros: "I am so grateful to have been provided delicious and filling vegan meals on this long flight. Thank you for offering a dietary option that is compassionate toward animals and contributes less to climate change! Now if only the planes were powered by clean, renewable energy... Hopefully that will become a reality someday very soon! Oh, and also the crew on this flight was exceptionally kind and helpful. Thank you so much!"
Cons: "I did not enjoy the turbulence, which I suppose is unavoidable. More importantly, I felt quite guilty about the greenhouse gas emissions of my flight. I have decided to cut down on my air travel as much as possible as a way of reducing my carbon footprint."

Pros: "Good entertainment options. Nice flight attendants"
Cons: "It would be helpful for short people to be able to adjust the head rest lower on the seat. More recent released movies would be helpful. More leg room. Not charging more money to choose seats."

Pros: "Arrived early!"
Cons: "Boarding seemed disorganized."

Cons: "KLM staff in the Prague airport were some of the rudest humans I have ever met. So incredibly uncaring and outright mean."

Pros: "The attendants took great care of us. Super smooth flight."

Pros: "Nice to have a wrap for the snack."
Cons: "Would have preferred boarding by row - back of the flight first so would have been more organized."

Cons: "We did not get two of baggage at the destination."

Pros: "Nice crew; clean plane; decent dinner"
Cons: "No entertainment system; insufficient knee space"

Pros: "Great service"

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)"

Cons: "Unaccompanied minor flying to Lisbon overnight. Bag was lost. No real effort to assist. Bags of unaccompanied minor should be treated with priority."

Pros: "Boarding was quick, Flight on time....just a regular service and plane"
Cons: "Terminal 3 Manchester is not worth staying longer then necessary, loud music, crowded....old"

Cons: "Bag was lost"

Pros: "The cabin crew were pretty good. That's about all that was good."
Cons: "I paid almost $400 for upgraded seats. When I got to the airport-- no seats-- both ways!! i didn't even have regular seat assignments. I had to choose from the last few seats available. 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: "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: "The flight was very good, specially considering it was a daylight one. Staff was friendly and servicial. Tue food was above the industry's average."

Pros: "quick boarding, responsive Airline stewardess, very polite."
Cons: "temperature control was not good, service was fine, seats were not comfortable. plane need to be cleaner."

Pros: "Friendliest economy class service I've ever encountered."

Pros: "Special treat for King's Day Friendly crew"
Cons: "15 min late boarding 30 min delay leaving the gate Very little leg room"

Pros: "The flight was not crowded and that was a nice surprise for a transatlantic flight. Each passenger was offered a personal bottle of water upon boarding, cabin crew was very nice and professional. The flight was on time and we arrived at the airport of destination even ahead of time!"
Cons: "There was no soap in the toilet..."

Cons: "I purchased a ticket that included one checked bag but their system said I purchased a ticked which didn’t include any checked luggage and I had to pay $60 to check my bag. Very frustrating!"

Pros: "The choice of entertainment is huge"
Cons: "The fisical conditions are terrible. Seats so narrow and rows are so close, that you practically pooched into your neighbors, those that behind don't let you to recline your seat as then your seat is in their face. It looks like American Airlines hopes to exchange your reality with virtuality, but our bodies that we are for some reason taking with us on that itinerary - suffer."

Pros: "Food."
Cons: "No audio."

Pros: "Given the choice I would hands down pick Finnair over a US based carrier the Europeans provide bigger seats and better service... Little things like hot towels, extra wine and chocolate after meals was truly appreciated..."
Cons: "Im an amateur traveler and I could have used a little more info at the gate and about getting to my connection I had no idea where it was and that you had to go through a passport line to catch the connection. Came close to missing my connection..."

Pros: "Friendly service, clean airplane, great food."
Cons: "No leg room in economy. Worse then United and American Airlines!"

Pros: "I was very satisfied by the flights by Finnair - kind personnel, good food, on time flights."

Pros: "I flew in economy. 9+ hours from ORD to HEL. The seat was average size. We were provided with a pillow, blanket and headphones. I did not use the in-flight entertainment, which was on an LCD screen. It was warm, so i didn't use the blanket. I also brought a neck-pillow, which is vital on overnight flights. They served a full dinner shortly after takeoff: I had meat lasagna which wasn't that bad, along with corn, a roll w/ butter, two saltine crackers with decent cheese and a chocolate pudding. Upon waking, I ate the breakfast, which was scrambled eggs and two sausages and a roasted tomato, a roll with butter, fruit cup and orange juice, coffee on the side. All pretty good, it was nice to have a meal before deplaning in Helsinki and waiting to get through passport control. Attendants on this flight were quite friendly. Check-in was run very efficiently. No problems with luggage. All in all, a real bargain price, and I got more than I bargained for."
Cons: "As for the downside, I had no significant disappointments on the long leg of my flight on Finnair. I hope my return flights will be just as good."

Pros: "Great customer service; food was good; excellent movie selection"
Cons: "For some reason about half of the passengers had to have their boarding passes reissued so departure was delayed- thus arrival was delayed & some passengers missed connections- I had plenty of time so it wasn't an issue for me"

Pros: "They lost my bag."
Cons: "They lost my bag."

Pros: "The crew was friendly. We were delayed, but I think that's because we were waiting on travelers with delayed connecting flights."
Cons: "The food was very heavy, heavier than airplane food usually is. The touchscreen TVs were not very responsive."

Pros: "Finnair was every bit as good as the best European airlines I've used in the past. Compares favorably to British, KLM, Swissair, etc. Service was top notch, good food, entertainment, comfort, airport lounge, etc."

Cons: "You have canceled my flight and you have just sent me an email."

Cons: "Crew wasn't attentive. Seats were small."

Pros: "We had a very reasonable fare that included two meals a glass of wine and movies. We weren't expecting any thing more than a plane ride. Thank you FinnAir."

Pros: "IT WAS THE MOST ENJOYABLE BUSINESS CLASS FLIGHT I EVER HAD. THANKS FOR THE HOSPITALTY AND SERVICE."

Pros: "The crew was friendly."
Cons: "The seats are cramped and the most uncomfortable I've ever sat on. An 8 hour red eye flight made it unbearable. The food is pretty terrible too. This is the last and only trip I'll be flying Finnair."

Cons: "My luggage was lost"

Pros: "Perhaps that we eventually got there and that the plane did not crash"
Cons: "Everything"

Pros: "Flight was ok"
Cons: "I didn't like the fact that it was delayed, with weather being in good condition"

Pros: "Flying out of Chicago we had a 3 hour delay. Caused me to miss my connection. The cause was "plane availability". What? It wasn't weather related in the least. Once the flight left the ground, the trip was very pleasant. But, Finnair should have made some sort of compensation to the passengers. They did not."
Cons: "See above"

Pros: "On time , excellent service"

Pros: "Schedule is on time."
Cons: "Food was not much excting and seat distance was rather short, making uncomfortable."

Pros: "Friendly and competent crew, on-time performance, clean and pleasantly appointed cabin, non-stop service always beats transfers!"
Cons: "Cramped seating (A330) for such a long (8.5 hrs) flight. U.S. catered food was mediocre at best."

Cons: "It is ridiculous that they would not allow you to select a seat for free at check-in. There were many unoccupied seats, but some families with children were seated separately, so there was a lot of seat changing before the take off."

Pros: "Flight attendants"
Cons: "Operated by American. Delayed for 4 hours"

Pros: "Nothing"
Cons: "Flight left 4 hours late due to mechanical problems with a very , very old plane. I paid extra for an exit seat that (bc the plane was so old) had cold air seeping in that even with 4 blankets on, a sweater, my jacket I was frozen the whole flight and caught a terrible cold that I have now had for a week."

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: "Flight was not super crowded. Crew were lovely."
Cons: "No seat back entertainment...had to endure The Charlie Brown movie, Nelson Mandela biopic and lousy boxing movie. Seats extremely small...would have been awful if plane was at full capacity. Plane very dated...no frills"

Pros: "Food ok. Service fine, grew nice."
Cons: "Last on board no cargo space..Sears are not great. Passenger behind my wife was pounding on the video games I the entertainment system the whole flight."

Pros: "It was Iberia airline"
Cons: "Put in call light three times without response. They just shut it off!!"

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

Pros: "Everything else"
Cons: "Both the British Airways attendant who check me in in Chicago, and the British Airways attendant who checked me in in London, were not paying attention to my final destination and did not mark my luggage for my final destination."

Cons: "When I arrived at CMI no ticket was issued for my second leg, so I could not use the internal transit bus to at Terminal 5 at ORD ("for ticketed passengers only). I had to exit use the external train (which was delayed) and go through the very slow Terminal 5 security. Almost missed my ORD-LHR flight (arrived at the gate after the official closing time)"

Pros: "Not much."
Cons: "The flight was delayed about 5 hours due to reasons no one really seemed to understand. Food was pretty bad as well."

Pros: "Seats were comfortable with plenty of room."
Cons: "Plane was broken and we had to wait 3 1/2 hours to get a new plane. Crew kept awkwardly mentioning during every announcement that the delay wasn't their fault... My husband's entertainment screen was broken and flickering so much that all shows/films were completely unwatchable. My screen began flickering 1/2way through a film."

Pros: "Checking was a breeze and there were no hassles getting through security. The flight was great and they even had a vegetarian option for my meal! I would highly recommend to anyone for International flight!"

Pros: "Good service"
Cons: "Ancient aircraft."

Pros: "I did not like anything about this trip."
Cons: "Our flight from Chicago to Paris was managed by Finnair, but flown through American Airlines. This was the second disappointing flight on American Airlines. Our first flight was repeatedly delayed over three hours and then canceled. Everyone had to take a new flight the next day on the same plane which was scheduled to be fixed that morning prior to departure. We boarded the plane 45 minutes late and then were informed that the part needed to fix the plan had just cleared customs. After another hour of waiting on the plane, we taxied to the runway and the returned to the gate because another part needed to be fixed on the plane. We waited another hour and a half on the plane before finally taking off. Upon our arrival at Chicago O'Hare, we waited on the tarmac for 30 minutes before the ground crew parked our plane. Which brings me to this flight from Chicago O'Hare to Charles de Gaulle in Paris. Our flight was delayed for maintenance repeatedly for 2 hours and then a new plane had to be brought over. By the time we boarded we were almost four hours behind schedule due to a logbook problem once we boarded the new plane. The plane itself was small - the size of a domestic flight - and VERY cramped. On both of the flights we had no TVs in the headrest. This is something that I have always had in economy class on international flights. It was by far the most uncomfortable flight I have ever been on. Because of the delay, we had to reschedule one of our two connecting flights. I was assured that our bags would still arrive at our final destination. When we finally reached our final destination, we found out that our bags had been lost along the way - most likely because of the flight being rescheduled."

Pros: "Staff was kind, flight itself generally went smoothly. The boarding process itself went fairly quickly, and I was able to disembark within minutes of landing."
Cons: "This Finnair flight was operated by American Airlines, but American Airlines did not notify me about the change in flight number until I called in a panic the night before because I was unable to check in. The plane was nearly 2 hours late departing from Chicago O'Hare with no explanation given. 1hr and 45 minutes is a long time to sit without going anywhere. Food was incredibly uninspiring and the staff was kind, but generally seemed distracted. I asked for a beverage at one point, but the flight attendant was too busy trying to get the passenger next to me who was passed out on sleeping pills to put the window shade down to give it to me. American Airlines is one of the only carriers left that has not upgraded to individual entertainment units for transatlantic flights and so the entertainment was like something straight out of Mad Men. Probably my worst flying experience to date."

Cons: "International flight delayed 2 hours for multiple mechanical issues. 45 minutes before boarding, we were given a $20 voucher for food and drink (which we couldn't spend on snacks, just big meals, which was undesirable so late at night). Flight itself played Mission Impossible 4, then a kid's cartoon, then nothing the remaining 5 hours. Very uncomfortable for those who can't sleep on planes."

Pros: "Flight attendants were grumpy, food was horrible (even for airplane standards), entertainment selection subpar and boarding was confusing (i.e. they was a group "b" and a group "2"- both different? ) received no nice comforts such as eye mask, etc"

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

Pros: "The staff were incredible and helpful. The entertainment made the flight go much faster. The airplane was comfortable and clean. Great flight"
Cons: "The passengers next to me smelled severely of body odor. I know that this isn't something the flight crew can do anything about but it made my flight really uncomfortable. Thankfully the seat next to me opened. So I loved a seat away- but even that couldn't mask the smell!"

Pros: "Good food - two meals at just the right time."
Cons: "I regularly fly between Chicago and London and dread having to get on AA90. The planes are ridiculously old with barely any legroom and no seat-back entertainment. On this occasion, my friend sitting next to me, who is 5'10" had his knees right up against the seat in front. When the passengers in front reclined it was almost impossible to get comfortable. There is no seat-back entertainment. For some this may not be a big deal, what with iPads and other devices, but it speaks to AA's failure to consider it's customers comfort and ease on long-haul flights."

Pros: "We didn't die"
Cons: "Poor air quality No leg room No room in the plane to move about or stretch Terrible food"

Pros: "Sat next to tall, broad shouldered fellow but otherwise fine seats. Food was ok but too cool."

Pros: "Crew was nice and helpful. Food was good."
Cons: "Tiny seats and no leg room!!!! I am not a big person."

Pros: "The flight did get us there."
Cons: "This flight had about 6 different airlines listed. I was supposedly flying Finnair. Make no mistake, this was an American Airlines flight. On an old plane with crummy entertainment, uninspired food, and uncomfortable seats. But we did get here."

Cons: "When I booked the flight there wasn't an option for a special meal and I have dietary restrictions so I was unable to eat any of the food on the plane."
