Pros: "One on the plane, the flight was fantastic! Great service and food. Comfortable for a long-haul flight. Very modern aircraft with nice entertainment system. Overall great experience."
Cons: "Scheduling! We were 4 hours delayed after I had already had a flight cancelled that day. And this 4-hr delay caused me to miss my connection.

Cons: "We were delayed for quite some time with no explanation."

Pros: "Requested for a aisle seat. Done without any issue. Very good food."
Cons: "Airport in Istanbul"

Cons: "the boarding was delayed and i missed my connection flight and have to stay 8 hours for another flight."

Pros: "Timing. Food and service"

Cons: "Istanbul Airport: Overcrowding at Arrival / Transit Terminal Way finding-poor signage for transit passengers"

Pros: "They offer 3 meals"

Pros: "Friendly staff,"
Cons: "My infotainment center was broken for the entire 13 hour ride. Luckily I had my phone but it would have been nice to have the expected entertainment options. The service carts only came through twice leaving a many hour gap with no drink or food service."

Pros: "Stewards and stewardesses were friendly and very helpful."

Pros: "Had ti spend while night in the Istambul airport. ...."
Cons: "No connection till following evning"

Pros: "Entertainment was OK boarding was a good comfortable sitting."
Cons: "I did not have an option to order kosher meal when I did my online check-in so I called customer service and the lady on the line barely spoke English and even though I warder kosher meal and verified it with her when I go to the plane the crew told me they don't have a kosher meal for me. The crew was unwilling to help me find something else to eat and they were very rude. I am very disappointed of their customer service standards. I will not use Turkish Airlines again."

Cons: "No no WiFi. Boarding time was late. Took over two hours. Management staff in the office was inconsiderate and rude."

Pros: "Service, Media"
Cons: "Seat room, very tight."

Pros: "Food"

Pros: "Everything"
Cons: "nothing"

Pros: "I upgraded to business class at a somewhat reasonable fare ($999.00) additional. Experience was much better than in Economy."

Pros: "First time I've had a gift in economy! Very minimal, but nice! Food was very good - especially for airline food. Crew all very nice, and pre-flight in SFO was efficient and pleasant."
Cons: "I'm a wheelchair passenger, which was a DISASTER in Istanbul!. It took nearly an hour to get to off and to passport control. And on the plane, it was very uncomfortable because of so little leg room. To get out of the window seat to go to the toilet was as bad as it gets, because of row in front with reclined seats - only possible to scoot across in sitting position. Not easy....!"

Pros: "Everything."
Cons: "Too small legrom."

Pros: "Staff are EXCELLENT"
Cons: "Internet was spotty."

Cons: "It was delaid too long"

Pros: "Worst airline ever"
Cons: "Worst airline ever."

Cons: "Everything was pretty good."

Cons: "Cabin was too hot. I complained and they adjusted it. The seat really doesn't go back much at all."

Pros: "Good food"
Cons: "No bed to sleep in"

Cons: "My first time flying with Turkish probably my last. Too many delays, first from SF to Istanbul and then the worse part no one was able to tell me from which gate my flight to TLV, I received at least 6 emails from you saying a different gate each time and we had a delay almost two hours in Istanbul. Because of all the delays I missed a few important phone conferences regarding my business. Unprofessional service! if I was running my business the same way I had no business! Not going to do this mistake again!"

Pros: "It is just superb"

Cons: "Wheelchair assistance is the worst when we fly with Turkish Airlines"

Pros: "Everything was great"
Cons: "My suitcase is dirty and full of grease on the side"

Pros: "Staff,food excellent. Very smooth take off and landing. Excellent pilots. As a Turkish citizen I'm proud of THY.,"
Cons: "Narrow seating area."

Pros: "I had a really long lay over and got a free hotel. None of the airline personal will help you find the hotel desk you need to get to, but if you keep asking around you'll find it eventually(in arrivals next to the starbucks). Shuttle service to and from the hotel. The hotel was fine(I mean not great but it was descent)."
Cons: "The flight attendants aren't super nice and if they don't understand you they kinda just move on. So that was sort of annoying."

Cons: "Several TVs were not working. While some were repaired the TV for my viewing did not work. Though it was set right it failed raw weal times."

Pros: "Every thing"
Cons: "None"

Cons: "No leg space for tall people, alas"

Pros: "The food and entertainment system was excellent. The headphones were painful after a movie. But you can link personal headphones into the adapter which is providex."
Cons: "The airplane didn't seem as clean as expected. The crew was adequate but not around between the main meals."

Pros: "The seat was good"
Cons: "The crew was not at all good, I had to call them so many times for one thing, not at all managed well"

Pros: "Boarding"
Cons: "Staff not fluent & clear in English"

Pros: "Kind. Generous. Competent. Thank you."

Cons: "There was nothing I didn't like"

Cons: "Didn't have a dinner option available.......ran out of chicken for dinner"

Pros: "Everything"

Cons: "SAS had simply cancelled the flight and is effectively unreachable for the refund."

Pros: "The crew was very attentive."
Cons: "The seats are tight and uncomfortable. Emirates and Singapore airlines have much more space in economy class. They also have better food. The worst new development is that you have to pay an additional charge if you want to sit together. That is pretty ridiculous for an international flight AND when you have a small child with you. I can see doing that on Ryan air, but that is pretty low for a Scandinavian airline. Scandinavians have a very strong sense of family."

Pros: "My first part of the flight, from SFO to CPH, was good. It was the second part that was terrible."
Cons: "SAS never emailed the second boarding ticket and there was no agent at the gate to help me print one. I paid $20 days in advance for a front aisle seat (6E), but was boarded last (group H) and had to put my carry-on in aisle 26. The stewardess was very rude and seemed racist towards me."

Pros: "Yea"
Cons: "Its simple. Turns out i had to pay 360 dollars for my baggages which was hever specified in the time i was purchasing tickets cause they said im flying without and i can come back with. Who is flying without baggage intercontinental for 1 month? And 3 baggages didnt arrived. Thanks"

Pros: "Cool crew"
Cons: "More leg space on economy section"

Cons: "Seats and spaces seemed a tad smaller and less comfortable than other airlines"

Cons: "SFO-Copenhagen was cancelled. Only hint for that came from Kayak which I didn't even use for booking (I used Flyus). Sas and Flyus didn't notify us and sas customer service had to actually use 5 min to verify that flight was cancelled after we called them. That left some poor rebooking options. Anyway, I am very disappointed how Sas didn't notify us. It would have been even nastier if we had got to the airport before realizing that flight was cancelled."

Pros: "For a middle seat, it wasn’t bad"
Cons: "The seat I selected was changed. I selected 45C and was assigned 54 E Upon check-in. Why? An aisle seat vs middle seat when I paid full faire is unacceptable. Also it was not made clear that I would have had to pay to check luggage. $120??!!!! I always carry on and this could have been easily avoided by not bringing gifts. Again, $120?!!!!! On top of an $1100 flight? You have to be kidding me."

Pros: "entertainment in the back of the front seat with great choice of movies"
Cons: "I would have liked to have had the chance to purchase a better seat. When I asked about it at check-in the plane was full. So I was squeezed in the middle section which made it quite uncomfortable, especially if you have to get up more frequently as an older person, but your neighbor is asleep. A notification about the possibilities for seat purchases would have been great!"

Cons: "Delayed flight - 2 1/2 hrs. No advance info. Departure gate change after check in. No Info at original gate. Unfriendly staff. No apology. No explanation for delay. Food substandard, even for cheap airlines."

Pros: "No problems. I was satisfied"

Cons: "When people lean their seats back their heads end up in your face and you are forced to lean your seat back to make separation from passenger in front of you"

Cons: "Limited selection of movies No food choices No snacks offered during flight First European airline to fall below the standards of US airlines"

Pros: "Being on time"
Cons: "Unfriendly crew"

Pros: "Liked the ticket price, the service, the food and the onboard free movies, free water bottle, free ear plugs."
Cons: "Nothing--it was a good flight - on-time and with little turbulence."

Pros: "Seats are pretty comfortably and spacious for economy class (I’m small though, so take that with a grain of salt). The lunch was pretty solid, would have preferred a hot breakfast. The vegetarian breakfast was grilled veggies with fruit and yogurt on the side, kind of a mish-mash of things."
Cons: "- Would have liked a better breakfast - More entertainment with subtitles (esp foreign films) - More entertainment selection"

Cons: "No food or even water"

Cons: "I would like more checked baggage allowance."

Pros: "The plane from SFO to Coppenhaggen was modern and clean. The flight crew was friendly and efficient. I would fly with them again."
Cons: "The seat was not well padded for the bottom.@9 m"

Pros: "Power in the seats!"
Cons: "That plane was so hot!"

Pros: "I purchased Plus and found it a good value. My seat on the overseas leg was comfortable -- though it could have reclined better. The food & drink service was conducted as at an elegant restaurant."

Pros: "The gate agent at check-in was very helpful and knowledgeable. The entire ground crew did a good job. The crew was friendly and attentive. The plane was clean. The entertainment options were more than adequate. Bathrooms were well kept."
Cons: "I know you can't expect coach to be luxurious. But the space between seats in the airline industry in general have gotten ridiculously small. Words were exchanged between my wife and the lady (nothing extreme, but still) in the seat in front of her. When the lady leaned her seat back, my wife could barely watch her movie. All in all, I would definitely fly SAS again."

Pros: "The crew was nice, the plane was large and had many bathrooms. The seats were comfortable enough and there was a good selection of movies to watch."
Cons: "The boarding process was completely disorganized and hectic. The woman making the announcements on the plane was extremely soft spoken and the PA system was static-y so I could neither hear nor understand any of the announcements. The refrigeration system for the food also broke down on the plane so we weren't fed our second meal. Instead, they chose the cheapest and most unappealing snack of plain almonds to give us. Despite confirming our luggage situation with us at the first airport repeatedly (because of our connecting flight) SAS still temporarily lost our baggage when we arrived at our final destination and caused us to stay an additional hour at the airport after already having spent an exhausting day travelling."

Cons: "Flight delayed so that would not be able to make the SAS flight. Therefore had to switch flights to go to CHicago instead. But initial flight was booked under alaska--but boarding pass unable to be printed from any of the kiosks and we were told to talk to American. American didn't know anything about it. THen stood in Assistance line for 45 minutes to be told that we needed to talk to VIrgin American. They rebooked us on to American, which then promptly was also delayed for several hours, and we thereby missed our connection. Throughout the process there were no customer service representatives either in person or on the phone who were remotely helpful. Overall, worst travel experience of my life."

Cons: "We couldn't check in online because we had an infant in arms. So we tried to check in there. There were 3 different terrible queues. One to use the machines, one to check bags and another for special situations. We tried the machines, didn't work. A rep told us to go to the special situations line. There was a rep there that was trying to prevent people to getting into the line because it was sooo long (1+ hr). So we tied the machines again. Didn't work. So we convinced the guy to let us in the special line. It was nuts. We waited as our flight got closer and closer. Right when it looked like we might make the flight, one of the TWO reps left. When we finally made it, they said we wouldn't make the flight. We rebooked and had to pay extra. WORST travel experience ever."

Cons: "The SFO crew was not helpful at all. Upon check-in, the SFO to Copenhagen leg of the flight was 2.5 hours delayed. When I expressed concern to the SFO ground crew, they said "You'll be taken care of in Copenhagen" in a very dismissive manner. I noted that we would miss our connecting flight (Copenhagen to LHR) and that there wouldn't be another direct flight that day. The SFO crew member told me that I was wrong that there was another flight available (a 4:30 pm flight). I told her that that flight wasn't on the SAS website and she told me that I didn't know what I was talking about in a rude manner. When I arrived in Copenhagen, the ground crew informed me that there was not a 4:30 pm flight and there never was. To get to London, I had to be fly first to Frankfurt then to London on another airline. Overall, this delay cost me over 6 hours. Utterly unacceptable and will never fly SAS again."

Pros: "Food, crew, entertainment"
Cons: "We departed almost 3 hours late. No explanation given over speaker. No compensation, no apologies."

Pros: "Great!"

Pros: "Passenger and Hannibal and Ben, crook with cop father. Excellent movies"
Cons: "Faster arrival"

Pros: "Crew and plane good. Friendly and English was excellent."
Cons: "There was a delay because of a software issue. They had to shift people around manually because of it. Baggage Fee was extremely high (> $50)"

Pros: "A340 just had a remodel. No media boxes installed under the seats taking up foot room"

Cons: "When purchasing the ticket there was no mentione that bagage was NOT included something which I assume when flying with an All Star airline. Ended up paying an extra 70 € for my luggage - not happy."

Pros: "It was a pleasant flight with friendly service. Boarding was smooth and efficient."
Cons: "Food choices and limited entertainment. I know that SAS need to remain competitive, but strict limits in drinks seems a bit cheap."

Pros: "Comfortable seats, nice selection of movies. The best price at that time."
Cons: "Crew attitude was not pleasant: no smile, no "you're welcome", as they were robots. Food was terrible."

Pros: "The seats were comfortable. Two meals offered for the 10.5 hour nontstop flight between San Francisco and Copenhagen."
Cons: "A little more leg room. Ability to change seat once reservation made online. The SAS website does not show your seat relative to entire place seat availability. Would have liked 24 hour customer service by phone option. They are actually closed for phone calls at night."

Pros: "paying extra for more legroom"
Cons: "Everything, small seats, lack of variety for movies, poorly trained staff, lost baggage, delayed flight and missing connection. SAS has dropped in quality"

Pros: "Introduce meals even to economy class"

Pros: "I upgraded for reasonable $$ and it was great - will do it again! Flight was in time, easy, friendly service and good flight"

Pros: "Passenger"
Cons: "Not much talk from captain about local weather and time."

Pros: "they let us sleep, keeping the light and announcements off during most of the flight"
Cons: "staff at the gate kept changing my seat without my consent. i had reserved a seat online and they ended up seating me aomewhere else."

Pros: "Quick boarding , no delay"
Cons: "Flight attendants were not so friendly and as entertainment the movies were outdated."

Pros: "The Boarding was fast and the Entertainment ok"
Cons: "Minimal Service Southwest style. Not the best international trip."

Pros: "Entertainment comfy seats"
Cons: "Food could be better chicken too spicy for kids"

Pros: "Flight was breezy, no complains. Nice staff Food leaves room for improvement but over all a pleasant experience But please read below"
Cons: "So you lost my luggage.. These things happen. However.. If someone pays 8 k for a one way ticket you might be able to come to the conclusion that it's an urgent trip as is. And respond or /and follow up so that I know what to do as far as cancel all things and /or max out my cc to get the things I need. Nothing from you, no word. No one picking up the phones. 8 thousand dollars worth of silence."

Pros: "Friendly crew, the plane was Very new and had wonderful screens for viewing entertainment."
Cons: "Not enough leg room."

Cons: "My flight was canceled the day before my departure via email. The customer service contact number for SAS did not work--I tried multiple times over the course of 12hrs+. The online help page gave a 404 error. I had no way of contacting anyone from SAS. Later that night (night before I was supposed to depart), I received another email saying I was booked on a United flight about 5hrs earlier than I planned on leaving. I had to cancel my morning plans with my wife to make the earlier flight. I never (still, a week later) was able to contact anyone from SAS."

Pros: "Excellent service."
Cons: "Uncomfortable seats in business class and mediocre food."

Pros: "The direct flight makes a difference and leaving from SFO is easy. Boarding was a cinch and it was a pleasant surprise to find a pillow, blanket, and headphones waiting at my seat. Once we were settled in and in the air, it was a pretty comfortable ride. The in flight enteretainment has good content, as long as your console works. Meals were very good and served at good times. There was also plenty of water available at the attendants station throughout the flight. There's no booze offered with meals for free, so if you want a drink you're going to pay for it."
Cons: "There were a LOT of families with small children who clearly had never flown or did not like to fly. Despite it being close to the bathrooms, it might be a better option to get seats further away from the doors (the extended legroom also provides space for a hanging crib). I was woken up by crying quite a bit. While the legroom is good, the reclining angle of the seats counters that if you also don't recline your seat. Also check for seats with entertainment boxes under them, as you lose a lot of space to store your things and extend your legs under the seat in front of you."

Cons: "It was very cold."

Pros: "The flight was on time, and the food was fine. Blankets, pillows and cheap headphones provided."
Cons: "Uncomfortable seats, broken entertainment system, outdated headphone jacks, and disinterested crew."

Pros: "The crew was very attentive, helpful and wonderful. I’d like to mention food too: excellent, fresh and wholesome!"

Pros: "Of all the flights I checked this was the most convenient in timely manner and comfortable."
Cons: "Movie options."

Cons: "Boarding process could have been smoother"

Cons: "Things were very scratched"

Pros: "everything"

Pros: "Was on time! Not croweded!"

Cons: "2 hr delay"

Pros: "It was on one of their newer planes which meant that we had decent comfort and entertainment!"
Cons: "The seats were staggered between the middle and sides, so my family was eventually split across two rows. I hadn't expected that."

Pros: "Speedy boarding process, good meal choices."
Cons: "Plane was a little dirty. Entertainment was also a little limited in terms of new releases."

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

Pros: "Boarding was ok in Dublin, even though they habitually use one of the poor gates with inadequate seating and entry to the plane from the tarmac, not via a bridge. queing and check in were well managed however."
Cons: "Disembarked at Helsinki unto a bus. Despite landing roughly on time, this antiquated procedure effectively made the flight 20 mins late, as that’s when the passengers got to the terminal."

Pros: "All good. Very hospitable cabin crew, great service."
Cons: "Nothing."

Pros: "Nothing."
Cons: "They canceled the flight after 5 hours of us sitting on the plane. They sent us away and told us to check back in in the morning. There’s been no communication since. I’m still at the airport. It’s been 16+ hours."

Cons: "The time. Ity was very delayed. Almost lost my last connection."

Pros: "it was just okay. nothing spectacular."
Cons: "my luggage was misplaced and I didnt have it for 3 days."

Cons: "Food was terrible."

Pros: "Good flight, on time, nice crew"

Cons: "They have no charging points for the phone"

Cons: "N/a"

Pros: "It was comfortable and smooth."
Cons: "It was all good."

Pros: "Decent flight from SFO to HEL, friendly staff ..."
Cons: "Ran out of food options from SFO to HEL. I was sitting towards the end of the plane ... and no more chicken so got stuck with the pork and mashed potatoes options. Need more coffee aboard the flight. ANA cleans the bathroom periodically, and wouldn't be bad to do the same on long flights. The arm rest between seats don't go all the way up, only half way. If the person in front of you is asleep during meal service, the FA (flight attendant) won't lift the seat and it may be a very uncomfortable meal experience. Other airlines will have the FA do it themselves. ...and you need to be careful about staying awake to get food (otherwise you can get forgotten)."

Pros: "nonstop to Helsinki was great...I have done this route over 100 times and this was the first time non-stop. When you have 17-19 hours travel time in your head door to door and then it is 12 - you really appreciate the extra time. THANK YOU!"

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"

Cons: "Seats. Very uncomfortable"

Cons: "My meal had rice that was severely undercooked. The audio quality on the entertainment system was very bad and no English subtitles were available for the majority of the movies."

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

Pros: "Comfort"
Cons: "Choice of movies"

Pros: "Great service, staff and punctuality"
Cons: "They changed the plane & seats"

Pros: "The new Airbus A350"
Cons: "Onboard food and drink is quite expensive"

Pros: "Far better quality and value than BA, it's OneWorld partner."
Cons: "It was all good."

Pros: "We were kept informed about the delay"
Cons: "Has to wait 14 hours in Helsinki for a 25 minute connecting flight"

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

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: "All is satisified."

Pros: "Fantastic service staff food and beverages"
Cons: "Just slightly hard when laying down on the seat to sleep"

Pros: "Professional staff. Easy boarding."
Cons: "entertainment seemed more oriented towards Asian passengers"

Cons: "the flight got delayed for an hour and I missed a connecting flight. Was re-routed through Moscow and was at my destination point 11 hours later."

Cons: "Nothing"

Cons: "Wifi spotty"

Cons: "Delay"

Pros: "Vistas along Mediterranean departing Nice"
Cons: "Interesting conversation with fellow passenger"

Pros: "Movie selection ok."
Cons: "Minimal coach legreeom even for an average-height passenger."

Cons: "They left my baggage behind!!"

Pros: "Very comfortable"

Cons: "My luggage was lost"

Cons: "Late arrival caused late departure for 1 hour."

Cons: "Not offered a beverage ."

Pros: "n/a"
Cons: "The conditions were very cramped. The entertainment system was quite old and had very little selection. My entertainment system actually stopped working all together. I called for assistance from my seat a couple of times, but nobody came."

Pros: "Not much, seats are super uncomfortable"
Cons: "Better code sharing with KLM"

Pros: "It was very comfortable and pleasant."
Cons: "Could be a little better the service, the dinner was late"

Pros: "All went right namely the seats but the luggage condition is the worst"
Cons: "Air France is not a low fare airlines, I had to pay 225 USD against 3 luggages which is not acceptable. We should have the right for one luggage per ticket as all other airlines. If I knew this will happen, I wouldn’t use Air France and this will be the last time I buy a ticket on Air France"

Pros: "Entertainment system failed repeatedly."
Cons: "Entertainment system failed repeatedly."

Cons: "More options for gluten free food. Always get the same dish"

Pros: "Great food and friendly crew."
Cons: "Seatback system was old and not very functional."

Pros: "Crew was very friendly and seat in KQ is super comfortable in Business."

Pros: "Crew great."

Cons: "Boarding clusterf..."

Cons: "Seat was super uncomfortable. Could not fit in my legs at all, could not recline it enough. Maybe sufficient for a one hour flight, definitely not on an intercontinental flight."

Pros: "Over all everything was great, except the bags check in"

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: "Old plane."

Pros: "Food was good, crew was very professional and courteous. Flight was smooth."
Cons: "Coach was cramped and the video system didn’t work very well"

Pros: "SFO - CDG (Air France) was a great journey in all respects. But the one major reason for that was, the middle seat was empty. I was so fresh after the journey, would definitely recommend this flight to anyone."
Cons: "The flight was delayed by atleast 45 mins and therefore had to rush at the CDG airport to catch the next flight."

Cons: "Separated me and my wife for the whole flight! Could not accommodate us together. This reservation was made over 6 weeks ago !!!"

Pros: "Great service and food."
Cons: "Tv screen is resolution is to low. Hard to see details."

Pros: "Nothing."
Cons: "Everything. The crew seemed to skip over me and my husband multiple times. So we sat there with garbage the whole flight. My entertainment was broken and they had no solution but giving me $30 to use at the duty free shop the same day as the flighty. I paid extra for premium seating in an exit row and that was their idea of fair compensation. The crew ran out of vegetarian food so I didn’t eat anything but cold stale bread. The crew was non-existent most of the flight."

Pros: ". Budget airline with no legroom or extras"
Cons: "See above. Nothing specific to like."

Pros: "The staff was very nice and friendly"
Cons: "One hour delay without any information on embarking and another hour in the plane before departure"

Cons: "I did not like that i was in the bulkhead and there was not sufficient overhead storage for us. The bin was only big enough for 1 backpack. 2 of the 3 of us in that row had to go 2 rows back to store our luggage. This is very inconvenient when deboarding because I have to wait for many others to pass before I get a chance to walk towards the back of the plane to get my luggage."

Pros: "It was a wonderful flight and service . Hospitality and welcoming."
Cons: "Nothing everything was amazing ."

Pros: "Nothing"
Cons: "Canceled flight—absolutely no notification. Convoluted rebooking in whcuhbhey lies to us about what flights we were actually on. Spent a couple hours at Delta rebooking our trip. Lost prepaid night at hotel and dinner eaecatuon plus day of vacation."

Pros: "Boarding was on time"
Cons: "flight was delayed by 20 minutes Boarding got me through Sky priority quickly. Had to then wait in the boarding tunnel as the cabin was not ready. large queue Seats were exactly the same as economy so offered no added benefits apart from the meal on board parked in a distant area of the terminal and had to shuttle bus to 2E which meant a very tight transfer"

Pros: "The crew were nice."
Cons: "The boarding process was horrible and it involved climbing down steep stairs from the air tunnel to the tarmac to board a bus that took us to a far distance where the plane was parked. Had to new walk in the sweltering heat to the plane can climb up steep stairs in the heat! We were now kept in the plane for another hour with no aircondotion. It was boiling hot in there. We had to use the safety manuals to fan ourselves. We eventually left late and got to Lagos one and half hours we were meant to get there. Lastly not all the luggage arrived. Two days into my arrival and I am yet to get all my luggage. It was truly a horrible experience which was echoed by fellow passengers."

Pros: "Food and service was good and price was acceptable"
Cons: "Very long route"

Pros: "La entrada"
Cons: "El resto de cosas"

Cons: "Its been a week. My trip has ended. I still do not have my bags. Terrible customer service."

Pros: "Nice food Right in time Police and customs formalities easy"
Cons: "Poor comfort in business class No entertainment at all"

Pros: "Boarding and punctuality."
Cons: "Lagos boarding with rather annoying wait due to repeat hand check. Perhaps added security carried far."

Pros: "The seats are spacious. They give you great amenities such as a toothbrush, etc. The crew was very nice. The food was also superb for airplane food."
Cons: "The check in process was terrible at SFO. We all felt like cattle being herded on. It was such a mess. The seats are surprisingly uncomfortable in premium economy. The headrest is not conducive to sleeping."

Cons: "The food: asked for vegetarian but got incipit vegan... Mostly rice with coconut milk"

Cons: "I think I caught a stomach bug on one of the 3 legs of this route. More likely on last 2, i.e. Mumbai to RDU, as I fell sick almost 10-12 hrs after my last flight meal."

Pros: "Traveled fron SFO to CDG on AF in business class on an A 380. Lounge in SFO was smallish and not many choices in the food bar. Boarding was smooth. my second ride on A 380 in business and this trip reminded me quickly why I did not care for the A 380 on my previous trip. It is a huge plane with a huge sized business class which makes the cost less worth it compared to a Boeing. The crew were extremely helpful and caring. The food was acceptable. The seats on the plane were not comfortable in the lying position. Took a cab to our hotel in Paris (1st Arr) for a flat 50 euros. No meters."
Cons: "Arriving in CDG and facing a slow immigration with the passengers of this huge plane. I didn't care for the baggage delivery system. We were waiting for an hour only to realize that the arrival port for our luggage was changed."

Pros: "Amazing service, seat and FOOD"
Cons: "Nothing"

Cons: "Food and coffee were cold. Service on AF is getting worse."

Pros: "Boarding sevece was very nice and helpful Thanks so much"

Pros: "The food was good, the staff was very friendly and very nice,"
Cons: "The seat configuration in economy is unacceptable, the leg room is terrible and overall a very uncomfortable flight of more than 7 hours"

Pros: "Loved the movie selection and the food was good too."
Cons: "Too many interruptions. Every time there's an announcement, it interrupts the movies and some of the announcements were completely unnecessary and there were so many of them, it was like constant interruptions, really annoying."

Pros: "I like service of AF"

Cons: "The company failed to transfer my checked-in bag to the next flight during the transfer apparently"

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."

Pros: "The aircrew are very friendly. The staff at CDG were very helpfull with our connecting flight."
Cons: "The seats are very cramped for tall people, especially when the passenger in front of you reclines their seat."

Pros: "The boarding process was very smooth and we took off early and the crew was great and then we also arrived 30 minutes early."
Cons: "Nothing could be changed."

Pros: "N"

Pros: "The flights were on time and the staff was very friendly."

Pros: "Nice new aircraft - clean and comfortable. Entertainment selection and system is excellent. SFO airport is clean and efficient"
Cons: "I DO NOT like JFK airport. The signage is poor and it's difficult to figure out where you need to go. There aren't enough monitors and people in the airport are rude (including staff)"

Pros: "Delayed and no AC working..."

Pros: "Good friendly service. Flights were on time."

Cons: "I was on a flight to Dallas on an American Airline flight which arrived late due to weather conditions, and the connecting flight didn't even wait for me although they know why I couldn't make it on time. And I was only late for about 5 minutes."

Cons: "I'm getting to Madrid 24 hrs after I was supposed to"

Pros: "while our flight was delayed, they kept us well-informed about what was happening and didn't leave us in the dark. We were delayed because an fight attendant failed to show up, and there happened to be another off-duty flight attendant passenger on board who volunteered to work the flight so that we could still depart on time. Real thoughtful dedication!"

Pros: "Did not use"
Cons: "Tight seating"

Cons: "I got to Moscow, SVO. I didn't receive my bag. This sucks."

Pros: "NOTHING"

Pros: "The entire fly, connections, food and both crews excelente. Flight on time."

Pros: "Airline and crew looked after us and kept us informed. My app said the flight was delayed but the captain didn't seem to know this so we sat for half an hour or more after planned departure. Maybe he hoped to get an earlier slot. We were 30 mins late in the end."
Cons: "No food for purchase, just a drink and biscuit."

Pros: "Good service, as efficient as possible"

Pros: "No food at all."

Cons: "Late by 40 min"

Pros: "The comfortable sitting and good hospitality by staff. Timely departure and smooth landing of aircraft."
Cons: "Nothing"

Pros: "Na"
Cons: "AA worst airline People They have working in SFO Incompetent Rude Useless"

Pros: "Everything smooth. No hang ups"

Cons: "It was delayed for about a half an hour. Other than that it was great"

Pros: "On time"
Cons: "They charge for everything luggage they can see in the front desk. My 63 years old mother had her small size hand carrier, a travel tote on top (with her travel blanket and her medicine) and a crossbody passport size. They told her to put it in her tote!!! Only 2 items allows. ... In the plane she saw passengers carried way more than what that."

Pros: "Lots of free movies."
Cons: "No free food."

Cons: "it was really bumpy"

Cons: "Pathetic airline service especially towards senior citizens.. One of the worst airline.. Poor baggage tracking system and Etihad staff lacks knowledge about their own airline.."

Pros: "On time arrival despite two issues at the departure gate"

Pros: "The Good: The seat configuration available for an upcharge of $38 gave just enough additional room to make getting my frail elderly mother in and out of her seat and accessing items she needed from a bag stored under the seat ahead of me much easier and safer than it would have been in, say, the sardine can-like conditions of the coach section on United flights."
Cons: "The Bad: At boarding, American does not provide pre-boarding for those who need extra time. I was traveling with my elderly mother, who can walk (very) short distances but is quite frail. American was great about providing a wheelchair to the gate, but then we were on our own. Because there was no designated boarding for people needing extra time or assistance, I had to sharp elbow my way to the front of the post-first class boarders and talk folks into letting her through. Stressful for both of us."

Pros: "tvs at every seat"

Pros: "Friendly and courteous service."
Cons: "Small legroom."
