Pros: "I had heard about limited food options during covid flights but everything was tasty and generous. I always appreciate it when my initial flight books my check-in to my final stop and gives me all my boarding passes at once and Delta did just that. They were also really good at communicating updates like changes to the gate."
Cons: "People should just be prepared to be asked more questions than usual. It can definitely make you feel nervous but just remember that the new covid restrictions are stressful for flight staff just as much as they are stressful for you. Be cooperative and honest and you shouldn't have any problems."

Pros: "Kosher snacks! Thank you. Screens and outlets at every seat. Safe, controlled Covid protocols including de-boarding. Excellent!"

Pros: "The boarding was fast and very well handled."

Cons: "My flight from Chicago was two hours late and that's why I missed the flight from Atlanta to Buenos Aires.

Cons: "Plane was sat broken at gate and needed part to be flown in. 150 minutes delayed. Not acceptable."

Cons: "I am a 5'3" 125# woman who, unfortunately, had a middle seat assignment. The passenger to my right, on the aisle, weighed approximately 375# and took up 1/3 of my seat. The arm was not able to go down comfortably, and when it did it was not usable . The passenger on my left, window seat, was probably 6'7" and had to sit with a man spread in order to fit. I could not move and was extremely uncomfortable. The plane was overbooked so I was unable to move. Therefore, worst flight ever. Plus, I paid for a full seat and was only able to occupy half of it."

Pros: "The entertainment was wonderful the staff was nice."
Cons: "CONSTANT ANXIETY!! Our flight to Chicago was delayed. By 2 hours. This normally is not a big deal but it caused us to miss our connecting flight from Munich to Bremen. Then our new flight with a later time to Bremen was cancelled 20 minutes prior to boarding with no more flights to this area. The service center helped us redirect another flight to Hamburg, Germany. We had to fly to Vienna and then to Hamburg. We made it to Vienna after a 40 minute delay however, this delay caused us to miss our connecting flight once again. We were placed on an early flight the next morning to Hamburg which was an easy flight. When we got to luggage in Hamburg we noticed our luggage was missing. Supposably still in Munich. We then missed this flight and missed out on valuable time with friends who live in Germany."

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."

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."

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."

Cons: "Klm is the best, even on a 40min they served small breakfast."

Pros: "15 years ago I told myself not to fly Delta anymore. But these 2 flights Detroit to Amsterdam and back changed my mind. I enjoyed the flight very much and I'm looking forward to the next one."

Cons: "This was the most narrow airplane seat I’ve ever experienced. So uncomfortable."

Cons: "If only there was a way to be able to lie down and sleep - you would be pioneers in aviation"

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

Pros: "Once aboard the plane, all went well and I experienced excellent service from the cabin attendants."
Cons: "The flight was delayed (again!) for some 40 minutes and I was worried that I would miss my connection flight in Atlanata. Fortunately the pilot made up for the delay (probably costing the airline thousands in fuel). It seems these days that every KLM flight I take is delayed. This stretch goes back to 2015! Yet KLM prides itself as being punctual. Not the KLM that I have been flying!"

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: "We got to Amsterdam on time"
Cons: "1. Paying for the seats we chose...that will never happen again...I'll fly another airline first. 2. The food was terrible. I have flown KLM for years, this was not what I expected. 3. The plane was very dirty"

Cons: "None of our 4 checked bags arrived with us. This was despite ample connection time (2+ hours) in Amsterdam."

Cons: "Landlords gave an unpleasant service! Which continued with late of 50min of the flight, they didn’t do anything to help/ to provide the passengers the answers. The food was cold It was comfort place to sit. Bad experience with KLM"

Pros: "NOTHING"
Cons: "Having to change my seat to accommodate a rude belligerent passenger, who had taken my seat, refused to move until spoken to by steward. She then made my flight a nightmare, until I let her sit in my aisle seat. Even then she was not satisfied, she abused me the whole flight damaged the screen so I could not use it until the steward fixed it. Demanded that I except any and all alcohol to give to her to drink. When I am tea total she then continued to abuse me. I asked the steward to move me he just shrugged his shoulders and said there was nowhere else. This is definitely my the worst flight I have experienced."

Cons: "Flight was delayed, landing at vce took an additional 10 minutes due to no one at the jet way. Luggage service was very slow"

Pros: "Flight crew very nice"
Cons: "Paid $70 for seat with more leg room and was the exit role to main entrance. No overhead space for carry on: broken food tray holder. People stepping on my feet. And gather in your space waiting for bathrooms. Window seat had no room for feet because of closed door"

Cons: "Not enough legroom"

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

Pros: "The cabin crew was so kind, efficient, and attentive. All meals and snacks were delicious."

Cons: "Nothing good to say about this flight. The plane was old with no entertainment. The sits where very compact and not comfortable at all. The food was a sweet bread and water. The flight attendants were rushing and will take a while if you needed anything. I felt like I was taking a bus with graffiti all over the place."

Cons: "... ear plugs, masks, good food or even picking seats? I remember when it was all complementary and standard on overnight flights. Oh, and the vegetarian breakfast was unfortunately poor as well. I know you can do better, because you used to."

Pros: "I got some rest"
Cons: "unable to charge my phone or watch movies"

Cons: "Actually the Welcome on board announcement. The part where they special welcome loyalty program members. I do not get that... I am an explorer holder my self, but really?? so other paying customers are not as welcome. This is leftovers from the older days.."

Pros: "Good Experience"
Cons: "Nothing much"

Cons: "I can't take the flight because i'm not Chilean and I don't have a reembolse or other flight ,... nothing . Finally I take other flight with other company"

Pros: "was very quick"

Pros: "Comfort economy well worth the extra."

Cons: "OLD OLD plane with hard seats and tiny screens"

Pros: "Everything - Checkin, crew, food, entertainment"
Cons: "Nothing"

Cons: "One of the senior stewardesses we're very rude. Whether it's her personal opinion or KLM's policy, it's unreasonable to think that a 3 years old child could or should hold her pipi over 20 minutes, while they slowly and inefficiently trying to give out food. Several parents were there with the request to let us through to the toilet with small children and she smiled in our face and said "no, we will finish first and than you can go". She might be not fit for the job anymore, but KLM can't afford this kind of treatment."

Pros: "The crew were really helpful since I am a short person in putting my luggage away in the overhead compartment and attentive to everyone's needs. I am a fussy eater and don't really like airplane food but the food was actually really nice. We was given plenty of snacks and drinks in between meals as well. There was plenty of programmes to choose from to keep me entertained."
Cons: "The seats in economy were a little too small for a 12 hour flight"

Pros: "Quick (relatively) flight."
Cons: "Skinniest seat ever. Couldn't even lean back. I now have hunchback."

Pros: "delayed"

Pros: "Good flight, we got a nice snack despite it being a short flight, the staff was great."

Cons: "The crew on the Lagos Amsterdam route (in economy) are particularly unfriendly and brusque. This is my experience each time i fly this route in economy"

Pros: "Crew was excellent"
Cons: "Economy was very tight! Seats were uncomfortable"

Cons: "Our flight from Nairobi to Lusaka was cancelled for some reason and we did not find out until we happened to log into the website to double check our itinerary. They automatically rescheduled the flight only giving us 25 minutes to reach our next flight...impossible. so, after calling, we were re-booked again and forced into a 13 hour layover in Amsterdam. Our original flight plan had 4 hours. so, because we are a family of 7 with a baby, we had to buy a hotel room to rest, costing us a lot of extra money we had not planned to spend. We contacted KLM for help with the cost but were rejected. We also lost 5 bags somewhere between Chicago and Lusaka, but after 2 days, we received them."

Pros: "My bag was lost!"
Cons: "To have my bag delivered"

Cons: "Things were very scratched"

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: "Finnair cabin/seats, clean, quiet and comfortable airport in Helsinki"
Cons: "Not only the first flight got delayed for over 2 hours. I had to re-book the second - connecting - flight because of that. Now it made my layover instead of 1 h 45 m - 5 hours! Then the second flight got delayed!! So instead of 5 hours layover it was over 7 hours!!! Very inconvenient and upsetting experience. The only reason I booked these particular flights is because they were advertized as "the shortest trip" time on your website..."

Pros: "Leg room, friendly crew, good choices for entertainment, nice blankets!"
Cons: "The flight was delayed for an hour, but the transfer in Helsinki was easy, I made it to the connect flight just in time for boarding"

Pros: "Well oiled service machine."
Cons: "None."

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: "Good airline teamed up with crappy American brings them down. Don't waste money!!"

Cons: "Unwashed pillow and blankets, stains on the pillow"

Pros: "I liked that they said ...you need to wait for 5 hours for the decision to get you or not on the next flight...and how much it will cost you extra now after having a great night spent at the terminal."
Cons: "All that matters for Finnair is that the flight took off on time... If you make it or not....if you know where to go...why to worry! It is your problem now! We will charge you up to "current" price now!"

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."

Cons: "The seats were chargeable. I paid a higher price for extra leg room. However these seats were the same as other ones that were much cheaper. Why charging so much extra?! False advertising?! This is unbelievable."

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: "The ease at which the check-in and boarding was done"
Cons: "Nothing"

Pros: "The plane was good, the flight time was nice, just 9.5 hours."
Cons: "The boarding was kind of chaotic, but the crew was kind. The plane seemed comfortable but the seats sit too far back, so when the person in front of me sat his seat back, his head was almost in my lap. It made it hard for me to move or read or do anything. The food was super bland and the drink options were pretty limited. The entertainment selection was much more limited than most flights."

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

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

Pros: "Great service and great food."
Cons: "The long hours"

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: "Crew and entertainment great."
Cons: "Big 3.5hrs delay. Missed my connection."

Pros: "On time , excellent service"

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

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: "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: "planned time of departure Fare potential for getting 5 seats so I could get a good nights sleep"
Cons: "Plane left 3 1/2 hours late due to a mysterious mechanical problem that caused them to taxi it away from the gate more than once. Relatively little communication from American whose flight it was. Scheduled departure 10 PM. Actual departure 1:30 AM I reserved a center aisle seat in a row that was completely empty a day or two before departure, hoping to get the whole row. Didn't work out. Just before we closed the doors a couple arrived at the row and took up three of the seats. Darn it. But I still got a good nights sleep. Wish there was an option to check N/A on several of the options above. I didn't speak to a crew member. I didn't eat or drink anything. I never turned on the entertainment system."

Cons: "There was a very poor selection of movies to watch:( Last tim ei flew AA, and there was an absolutely huge choice . . . Would love to see that improved . . I think you have to cater for all tastes . . . and that definitely was not the case on my 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: "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: "Good service"
Cons: "Ancient aircraft."

Pros: "And perfectly on time!"

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: "The crew was very nice and helpful and the flight went well and was ontime, in fact early."
Cons: "I thought that I got one bag checked for free and another one would cost $50. But when I got my boarding pass I was charged $100."

Pros: "Crew was not very helpful, last time I fly Iberia."

Pros: "Crew were nice, and since it was actually an AA flight we got upgraded to economy plus. And the price couldn't be beat!"
Cons: "It was one of the oldest planes I've flown on for many years; single screen entertainment and uncomfortable seats. Food was unusual, but pretty poor."

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: "It is over a month now and I am still waiting to get my American Airlines miles awarded to my account. The trip was booked through FinnAir but operated by American Airlines. They are both members of the same alliance. The airline miles number was confirmed with American Airlines upon check-in. But now, American Airlines wants proof of my ticket receipt and boarding pass. I have my ticket receipt but who keeps their paper boarding pass these days? Hope my photo of the gate details suffices for my boarding pass."

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."

Cons: "Food service and better social distancing"
