Pros: "I love the food and the movies"
Pros: "I never usually like plane food but liked Turkish Airline meals on all flights I’ve been on so far"
Cons: "I do like turkish airlines but wasn’t happy with this flight. On check in we were left with seats towards the back of the aircraft. The lady seated neit to us in the aisle seat was in a wheel chair so was a problem if having to get in and out. I didn’t think it was fair that a person who depends on a wheel chair sits so far back on a plane. She also had to deal with our crying baby"
Pros: "The plane was too hot"
Cons: "Plane too hot"
Pros: "Full meal and entertainment system even for a shorthaul flight."
Cons: "Tight leg room"
Pros: "Great hospitality, food was as ordered, plenty of drinks, energetic staff"

Pros: "I loved the food and the staff are very helpful and friendly. I have always chosen Turkish airlines."
Pros: "Turkish do a good job of giving you a good service for your money."
Cons: "Why not keep us informed why there are delays before take off. Headphones that worked well without having to fiddle with the connection would be good"
Cons: "The serbice qnd food was terrible"
Pros: "Big plane, friendly staff, good food."
Cons: "Sometime, it gets a bit too cold."
Pros: "the seats were more roomier than the flight to istanbul."

Pros: "I liked the food."
Cons: "On the way back from Istanbul to London the plane was old and small, the TV kept shutting down,even the earpiece were not working."
Pros: "Charged me >$700 for missing a flight. This never happened earlier. Customer service girls are robotic: they just repeat the same lines. THY wasn't like this, something major has changed."
Cons: "Zero effort to reaccommodate."
Pros: "The staff were very welcoming and the seats were very comfortable"
Cons: "Flight was a little delayed"
Cons: "The food - I always have a v-meal - is sadly inadequate. Not enough of it, and very unimaginative. And they always supply the same thing, unless I was just unlucky to have the same thing three times in a row. Boarding was chaotic - a full flight crammed into a departure lounge with far too few seats. There were many families trying to board and the staff could barely cope."
Cons: "Have yet to arrive"

Pros: "Nothing"
Cons: "I book flights and they toke money and last minute when i went to the airport is not existing at all"
Pros: "Food was great so was service"
Cons: "All was good"
Cons: "My entertainment set didn't work"
Cons: "I missed my connecting flight in Turkey as flight was delayed. It was my worst flight experience because nobody wanted to help me. It took an hour of being ignored by various TA staff to eventually get my boarding pass to the next available flight to London. I nearly missed that one as well because of it. The staff in Turkey was rude and unhelpful and most didn’t understand English properly. There were a number of others having the same issues, it was an awful experience."
Cons: "The boarding was a little more chaotic, but the host airport has a major influence on that process."
Pros: "Better of most European airlines.. nice enough lounge and inflight service pretty good with room to improve for sure."
Cons: "Boarding was simply chaotic where staff isn’t managing the queue well separating business and economy. At arrival baggage priority meant nothing. Half the non priority bags arrived way before a massive batch of priority bags arrived. Defeats the purpose of giving your guest fast track immigration !"
Pros: "Friendly good service"
Cons: "Istanbul changing gate to get to such long walk"
Pros: "The amount of food and drinks we got was perfect, the movies, shows and other entertainment options were plenty and they had a great selection, and the sleep kit (slippers, socks, lip balm, etc) was very much appreciated and helpful. The staff were nice and professional."
Pros: "Everything was great, thank you for your service."
Cons: "NA"
Pros: "Professional and friendly staff. Excellent film selection."
Cons: "Not enough security staff at Istanbuñ and no one from the airline to assist. The queues were too long at security so I had to run to make my flight. Lots of other people had the same trouble and I believe my cousin missed her connection."
Pros: "N/A"
Cons: "Connecting both flights would be good"
Pros: "Everything was fine on this flight."

Cons: "My TV remote was broken. I could have used next seat but was too lazy."
Pros: "It is just superb"
Pros: "Low prices & generally good service and entertainment"
Cons: "This airline used to be excellent. Now, the prices have been going up and the standards down. Service not as good, food not as tasty, plentiful and varied, crew not as warm and attentive. Instabul airport was the usual chaos, which does not add to the experience for transfers. Also: boarding started late and of course was not done and time and since we lost our slot we were further delayed taking off. That made the transfer time even less and the situation more stressful."
Pros: "Comfortable, tasty"
Cons: "The flight was delayed in 40 mins Our entertainment system didn't work"
Pros: "All the movie options, the great food, the great service, and the timeliness of arrival."
Cons: "Nothing, it was great!"

Cons: "Seats could be more comfortable. Headphones are really not very good quality. Touch screen difficult to use (not very responsive to touch)."
Pros: "Best airline food I have ever had. Most comfortable long flight as well."
Pros: "Flight was ontime"
Cons: "1st class seats not as comfortable as other airlines. Food was nasty."
Pros: "The seat was good"

Cons: "Drinks were good, but food was bad"
Pros: "Very fast and cheap flight."
Cons: "Seats were extremely uncomfortable. Boarding was very chaotic."
Cons: "I travelled economy and found the seats not very enabling for big and tall folks as myself ! Other than that I highly recommend flying Lufthansa"
Pros: "Friendly crew, great food, comfy seats"
Pros: "The flight was adequate."
Cons: "Sandwich was extremely unappetising and there were no hot drinks. The worst thing was that in transiting from the SAA flight to the Lufthansa flight we were obliged to go through security which seems unnecessary. The security staff were awful. Bullying, rude and totally unsympathetic to the fact that having brought water from the first plane to the second plane we had to either drink it or throw it away. One guy in particular, a tall greying man evoked the worst stereotypes of brutal secret policemen. Perhaps he formerly worked for Stasi or he was having testosterone problems. Totally unacceptable behaviour."
Pros: "great over all experiance. Don't let the other negative reviews put you off"
Pros: "The Lufthansa app provides updates on plane status and gate number, etc."
Cons: "N/a"
Pros: "All"
Cons: "Nothing"
Pros: "Did manage to get priority transfer which I requested from Dubrovnik but was told. “We do not do those”"
Cons: "Rest of the flight was bearable nothing write about. Typical cheap alow cost flight"
Pros: "Ok"
Pros: "Crew was very nice and professional. We arrived early"
Cons: "Food was disappointing as was the wine. I am not a large person but I found the business class “bed” pretty narrow and uncomfortable."
Pros: "Everything that happened during the flight was fine. The service, the flight itself, and the landing – which was excellent."
Cons: "On the ground, neither the staff nor the signage made it clear exactly where to check in. I was sent to the Lufthansa counter, which didn’t open until 11:30, when I should have gone to the United counter. An hour of my time was wasted, which almost resulted in my missing the one-hour before take-off check-in deadline. The only reason I didn’t miss the deadline was because the flight was late taking off."
Pros: "See above"
Pros: "The crew was wonderful and this is consistent with my previous experiences with Lufthansa. The salami sandwich provided was actually very good."
Cons: "The slimline seats were not very comfortable. I would hesitate to fly Lufthansa's narrow bodies for flights greater than 2 hours."
Pros: "I liked the seats, the space for our legs and the crew members"
Pros: "All the staff were friendly and the complimentary food and drink snacks was lovely."
Cons: "Our flights were delayed both on the way there and back"
Pros: "DID NOT LIKE MY LUGGAGE GOING MISSING! IT'S STILL MISSING AND, AFTER RECEIVING PROMISES OF DELIVERY TODAY, THERE IS NOW NO RECORD OF MY LUGGAGE!"
Cons: "DID NOT LIKE MY LUGGAGE GOING MISSING. IT'S STILL MISSING AND, AFTER RECEIVING PROMISES OF DELIVERY TODAY, THERE IS NOW NO RECORD OF MY LUGGAGE!"
Cons: "I haven’t received my luggage and I have been in Mumbai for almost 3 days!!! I have to buy new clothes and plenty of toiletries, I have only had 1 phone call from the airline to tell me my bags never left SFO!!! Wtf!"
Pros: "The seats and space was ok. Exit from the plane was directly opposite the passport machines and the exit."
Cons: "The flight was very late leaving meaning I arrived in London over an hour late! With knock on problems!"
Pros: "Usual good service for economy class on this airline"
Pros: "All of it"
Cons: "Nothing"
Cons: "Refusal to board as our flight was a few minutes landing"
Cons: "The crew didn't seem particularly interested in helping anyone and worked hard to avoid eye contact. This was an unpleasant flight at best and given the option I will not likely fly Lufthansa again if given the option. I wish that I had better news to report from this flight. :("
Pros: "Gave us snacks when flight was delayed"
Cons: "Flight was delayed Entertainment app didn't work"
Pros: "The crew were very friendly and I liked that they always kept us hydrated with drinks. Before I even left on the trip I called the airlines several time with so many questions and the staff that I talked to each time were so friendly and helpful with all the questions that I had."
Cons: "The only thing I didn't like is that the boarding process was different than what I was used to. I usually board by zones and this time it was more of a everyone got up at the same time and everyone rushed to the front of the lines and some people would push me out of the way to get in front. ( even though we all had assigned seating) Second thing was that I had asked for a wheelchair for my mom and I had seen one waiting outside and was about to walk up to it but another person was limping up to it and put her stuff down on it so I didn't know if it was for my mom or her. I didn't have the heart to go up and make her move if the wheelchair was for my mom so we ended up walking the whole way to customs. I felt bad for my mom afterwards because her knees ended up hurting by the time we got to customs. I would suggest holding up signs of individual names for who the wheelchair is for. Other than that everything was great"
Pros: "Staff was very friendly and caring."
Cons: "No entertainment and half sandwich with some cookies was the only food we got."
Cons: "N/A"
Pros: "They held the gate for us as we got there about 14 minutes before departure."
Cons: "Was delayed in a connection and missed flight. No offer or help provided to get me and children on another flight without charging me ~$9000 for another flight. Paid out of pocket for another airline. Cannot believe the extortion and lack of service provided!"
Pros: "I really enjoyed my flight with Lufthansa. My gluten free meals were very good and the service was excellent!"
Cons: "It would be nice to be able to reserve seats ahead of time without charge"
Pros: "I have ordered the salmon fish dinne and the fish was totally overlooked, dry and tough. I could not swallow the fish and ate the tiny bread roll only. The second was breakfast wigh tasteless scrambled egg and mushroom and spinach. Both serving sizes were really small with just one side dish of fruits. I was hungry the whole 10 hours flight."
Cons: "Changed the chef or the vendors who supplied the meals."
Pros: "Flight Attendants were Excellent. Friendly, attentive, and caring! Thank You Very Much."
Cons: "Lufthansa changed our seats, splitting up my wife and I, after confirming they were together. Thank you to the Flight Attendant who reseated us together but "you know what" to the person that screwed up the seats in the first place. Also the on-line check in process was extremely poor, maybe "bad" is a better word."
Pros: "Service was good, the airplane was good also"
Cons: "This time we experienced a strong turbulence. It would be more helpful if the crew gave updates about the situation more often, was really scary. Also, the food was not good at all...."
Cons: "The flight never took off. We had to wait 6 hours in line, and they still couldn't rebook many of us. When I was finally rebooked on a Swiss Air flight, the flight was invalid, Swiss didn't accept it. I was send to various different lines, and they didn't even understand what my problem was. Finally after spending 2 whole days at the San Francisco airport, I could take off with a 30 hour delay. The Swiss Air flight was wonderful."
Pros: "The flight itself was fine."
Cons: "Chaotic boarding process and tarmac delays consumed the already inadequate prospective layover in Chicago."
Cons: "1 After long stand the line when i want to check in my Luggage i got shocking news According to checkin counter lady said Flight delay more than 2hours and can be 3hours no body knows how long will be delay, she recommended me to go from San Francisco to san jose airport to get another flight. it's time Enough she said , that time about 1pm, i am lucky that i arrived SF airport 3hours in advance so that i could manage to catch up another flight at the san jose airport, i had to go san jose airport from San Francisco by Taxi and the cost was 170usd because driver says over 50mils far a way i need to pay 50% more, i have a alot import meeting in germany, meeting schedule could be mess i was really shocking, how can i get back Taxi fee usd170??? 2. regards to Crew., one Passenger was collecting his handy carry luggage at Cabinet and he forgot to close Cabinet cover after he collected and it was opened that time one flight crew passing by to final check up before landing but don't see that cabinet door open, so one of passenger talk to her to close the Cabinet door, also handy carry luggage after used the passenger should Keep Under the chair for safety but even passenger keept (put) in her beside empty seat, the Crew don't say anything, it was many people keept in next empty seat area. According to rull must keep it under seat, but crew don't say anything I was very very surprised. it's very Dangerous to everybody people may hurt , i was very Scared and nervous. 3. in the dark room passenger can't see or feels that behind them whether crew come or not (passing by or not) Crew passing by and hit passenger but without saying sorry and just go a way. it's impossible... 4. i was standing at Exit door and look at the outside but same time crew came and said to me not friendly and without smile "Excuse me" and i go a way, i saw she crew want to put something inside at dress room. what i want to say the crew could be more nice and smiley face to passenger or could be nice can be wait 5 seconds but was really the way of tone is Racist, this is what i felt, really bad."
Pros: "On time and smooth"
Pros: "At a time when airlines are treating a plane like a flying bus, it's heartening to see Lufthansa's attention to detail for its customers both in terms of ontime departure, arrival and inflight hospitality is second to none."
Pros: "Latest movies few included"
Cons: "The space is so small. For 11plus hours my body could not move. I never had knee problem but they were so sore. My feet and body got extremely tight mid way in the flight. This is my first and last flight in your airlines."
Cons: "Food was lousy. I have not flown L for sometime, but the food was lousy. I don't remember it being this bad previously. They ran out of rice and chicken...and served me beef... The chicken was on the bone, instead of being off the bone...so harder to eat in small space."
Pros: "Everything was ok"
Cons: "Food was very bad"
Cons: "the monitor at my seat did not work and I could not watch any movie. Everything else was fine."
Pros: "Efficiency, courtesy, professionalism."
Cons: "none"
Pros: "New plane with very friendly and helpful attendants. Extensive entertainment system with usb charging ports."
Cons: "Food was mediochre, but what can you expect?"
Cons: "I was seated next to a family with an autistic child. Because they had checked in late, they were seated separately. The autistic child was unsetted by having to sit separated from both parents, causing quite a commotion during the whole flight. I couldn't rest during the whole flight. Lufthansa should do a better job with accommodating the needs of special cases like this, preferably when they book the flight or before they board. SFO boarding was slow and confusing. There was a backup being caused by having to seat 6 or more passengers in a wheelchair. Then, I followed signs for boarding in Economy, which was at the front of the A380. I was forced to the aisles to the back of the plane, where I prompty collided with other passengers that were boarding the rear entrance of the plane. Why wasn't I just asked to board from the rear entrance to avoid the congestion?"
Cons: "Entertainment didn't work"
Pros: "Professional crew"
Cons: "I think for the price I paid for the flight there should at least be a free snack to go with the free drink."
Cons: "Terrible airline, they charge for everything, but don’t give the client good service. I was yelled by a worker because I was having difficulties scanning my bag at the self-scanning-and-uploading-your-luggage that you pay $100 dollars extra Per bag. I don’t like this airline."
Pros: "See previous note about lost bag."
Cons: "See previous note about lost bag."
Pros: "Seat was comfortable. Entertainment was great. The service by the crew was great."
Cons: "It would have been nice if the armrest went as far back as the seat. Flying with my partner, she doesn’t sleep well on planes unless she can completely lean on me. The armrest between our seats only retracted to the upright seat level."
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: "Momondo sold me a so called 'go light' ticket (not disclosed anywhere though) meaning that only 1pc of carry on was allowed! No checked bags unless purchased. Could not see on the price of my ticket that this was the type of new generation low quality tickets. So tired of momondo."
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."
Cons: "I don’t like how the food on premium economy is packed in a cubic box that is really messy to eat from which the small plastic cutlery. Food quality is good, but feels like being an animal being fed from a bucket."
Cons: "Got asked to leave my seat in row 3 for one further back because I couldnt pull up my ticket mid flight to show it was my seat. Their system had me in another row so I missed out on the extra service offered to that row."
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"
Pros: "Movies"
Cons: "We were in 40G and H, bulkhead seats. I have never had such a hot plane (and I am a world traveler). We were both very warm (felt like 85 degrees- warm enough to not be comfortable). I was told by the flight attendant that people in back of plane were freezing. The breakfast was good, but the dinner was ok, but not ‘I wish I could have seconds” good. I lowered the rating because they never gave us more than the one bottle of water that was on our seats when we arrived. That may have been ok for the people in the cold part of the plane but not for us in the sweating part. Luckily we had brought a big bottle of water."
Pros: "Aisle seat"
Cons: "Nothing was complimentary"
Pros: "Easy boarding. Friendly staff"
Cons: "N/A"
Cons: "Luggage lost or misdirected and VERY poor effort in getting it delivered to me, once found. I still have no clothes, shaver, toiletries . . . or confirmation on when/if delivery will happen. Just simply disrespectful!!!"
Cons: "This has nothing directly with SAS, but since I experienced it during my flight there, they are responsible of it. I was waiting for the flight at the OSLO airport waiting for the flight to LONDON. I had ample time to work on my computer. In the big room by the gate there was only one spot where I found three electrical sockets hanging from a pillar or post. To my dismay none worked. My plug would fall off from each. To document, I took the pictures of the useless sockets... I complained to the lady at the boarding desk (she left before the SAS staff moved in), she did not even care... This experience frustrated me and turned an otherwise pleasant trip into a bitter one. Please install some working sockets in your waiting room! Flight SK 809 Confirmation: LN9M6O Departure: Oslo & other airports (OSL) Arrival: Heathrow (LHR) Time: Sat Dec 2 2017 3:05 pm CET - Sat Dec 2 2017 4:25 pm GMT Peace, Edip Yuksel +1 520 481 1919"
Pros: "This is obviously a very well-run airline. Boarding was efficient, the crew were warm and professional, and the overall feel of the aircraft was very Scandinavian-cool. I was most impressed with the meal service. We were served twice on our 9 hour flight, and both meals were hot, healthy, and the best I’ve had during a flight. The passenger in front of us was having a hard time with her sinuses, and the flight attendant (whose name I wish we had gotten) was very attentive and concerned for the comfort and well-being of the passenger. She insisted on doing anything she could to alleviate the woman’s difficulty. It is clear that the crew care about the passengers’ experience."
Cons: "We were unable to sleep at all during our overnight flight and landed pretty exhausted. Our seats were comfortable (complete with a moldable headrest to keep your head from bobbing around) but we felt too upright to fall asleep. The passenger in front of us reclined, but we were concerned about reclining into the already tight space of the passenger behind us. So we weren’t able to sleep, despite trying to get comfortable/somewhat horizontal. It seemed to be a mixed bag of asleep and awake passengers on the flight, so some people were unaffected by this issue."
Pros: "On time, easy boarding"
Cons: "The flight was nearly full and everyone seemed to have at least two cases. This caused lots of jostling for space in the lockers"
Pros: "Pleasant crew"
Cons: "Boarding was shambolic and the 737 is not as nice as the new A320 in terms of comfort or amenity. Boarding was all over the place - and the gate agents clearly need extra people around for a full flight. One person for 170 ppl didn't feel right."
Pros: "i ended up missing the flight, due to car accident which involved injuries."
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: "This wasn't a very long flight and I didn't eat or drink anything so there isn't really that much to say. But I can say that nothing was a problem at all"
Cons: "There were no problems"
Cons: "Unable to select seat/baggage until 22 hours before flight because not booked through SAS. Thought bagged was checked in online and had to pay More than the cost of the flight. Flight was delayed due to mechanical problem. Cabin very warm throughout flight."
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: "I was really disappointed at finding out at luggage check-in that I had to pay extra (£60.00) for my one regular-size suitcase. On the return flight I was told that this amount would be - as it turned out in my case - less than half, if I called SAS a day before departure. Why did I have to pay for the checked luggage at all?"
Cons: "We paid over $75 for each piece of checked luggage. We could have saved 40% by pre-purchase but were not warned when purchasing our flights for almost the same price as the cost of the luggage."
Pros: "Good experience. Nothing extra-ordinary. Only complimentary tea, water and coffee."
Cons: "Flight arrived on time."
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: "The food was very good surprisingly"
Cons: "Again the seats are too tight and they should not be allowed to recline"
Cons: "Out of all the staff on board they did not give me and a few others those blue customs form, so we made a huge line and when we got to the agent he told us we had to go all the way around fill one out and then come back. The attendants new that those were necessary why so many yet not one made sure we got them lousy service. I wish we got a crew that wasnt so insecure and cared more about providing a good service instead of caring so much over their appearance. I rather have good efficient staff what they look like doesnt matter to me."
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: "Did not use their services much but the stewards seemed nice."
Cons: "Flight was delayed, no entertainment, not many food options for people with certain dietary requirements."
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: "Clean and good food."
Cons: "It was a fine flight. Nothing to worry about. I liked it."
Pros: "The new cabin and video monitor are nice. Crew was polite."
Cons: "Food is the same as I flew last year. Taste is the same. Need some changes and variety. Movies can include more recent ones."
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."
Cons: "Not even one bag was included!! And to add a bag is extremely expensive!!! Paid five hundred dkk for one bag!!! Terrible service as well!!!"
Pros: "Quick boarding , no delay"
Cons: "Flight attendants were not so friendly and as entertainment the movies were outdated."
Pros: "Easy embarkation, helpful staff."
Cons: "Shock to discover that suitcases were not included in price of tickets purchased online. We had to pay the equivalent of $100 (australian) per case. My seat was extremely u comfortable as the cusihion was misshapen. The male passengers seated behind us were drinking alcohol and became loud and garrulous, making the trip most uncomfortable and unpleasant."
Pros: "Flight was Ok"
Cons: "Left till last to board flight. Case taken from me. Asked continually when I wld be taken as I am 83 and recovering from major operation. Told 45 minutes before flight but was taken 10 minutes ahead. Rush has left me very upset."
Pros: "The Boarding was fast and the Entertainment ok"
Cons: "Minimal Service Southwest style. Not the best international trip."
Cons: "Disorganization and unpreparedness."
Pros: "Flight was fine, cr"
Pros: "Same as above"
Cons: "Same as above"
Pros: "I was informed by email the evening before my return flight back to London that the flight had been cancelled. I tried calling multiple SAS offices overnight, and finally reached someone the morning of my flight and was rebooked to a different flight, via Berlin. When I got to the airport the booking hadn't been updated, so I had to go through the entire process again with customer service. Because of the flight cancellation and the difficulties rebooking, I was not able to book my luggage so I was charged a penalty fee at the airport when I was finally checked in for the flight via Berlin, and paid much more for my bag than I should have."
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: "Smoothest landing I have ever experienced! The one rating for food and entertainment is because you don't have an n/a tab on your site."
Pros: "Thanks to the staff while checking in my luggage I was able to check my bags directly from Stockholm to Mexico City via preventing me to loose a lot of time in London where I was supposed to check in and out because I purchased my trilp in two different segments"

I always try to book on TAP. Every single flight I’ve had with them has always been flawless. They’re more expensive than the pure budget airlines, but not much. That extra little bit I pay is worth it 100x.

Nothing. Everything.

Overbooked flight which led to big delay.

Awesome crew. Zero turbulence

The airline has lost my luggage.

Pros: "The crew was attentive but only on the basic standard service."
Cons: "I truly love that there are very few travelers. Also, I went through a lot getting to have done a covid test in order to travel, no one asked for it! Also when filling the custom forms they could have been and explain that one paper form was enough for a whole family"
Pros: "Good"
Cons: "Good"
Pros: "The crew."
Cons: "Fake marketing! They said it will be some snacks for economyXtra, and then 2 hours before the flight sending an email saying that the snakes will be charged! Disappointed!"
Cons: "I paid Xtraeconomy to have some snacks during the fly, and they end up coming with a trolley to pay! Disappointed!"
Pros: "The crew were very nice overall but one flight attendant in particular was incredible. I didn’t get a name but he was friendly, welcoming, and kind."
Cons: "I sat in an emergency row with an empty seat to my left and really did not like how the passenger in the row behind me kept getting up and walking into my row to get his stuff from the bins."
Pros: "Sleeping and being left alone"
Cons: "Food, Service by cabin crew because they never smiled"
Pros: "Amazing punctuality, both on the way out to Lisbon and on the return to London."
Cons: "Cannot really think of anything that needed attention on these flights."
Pros: "The food was great and the screw were nice and young ."
Cons: "The boarding process and charging 95 dollars for an extra bag is crazy."
Pros: "Good movie selection"
Cons: "Multiple delays for my flight. First the departure was delayed which I know can happen. Then we boarded and sat for over an hour before take off. Captain made up a story about the plane needed gas and said we would take off in 15 minutes. An hour and 15 minutes later we finally took off."
Pros: "Super friendly"
Cons: "Maybe a hot meal?"
Cons: "Flight to Lisbon late. Missed connection Now have 10 hour delay"
Pros: "The crew was really nice"
Cons: "The food and proving more snacks and drinks"
Pros: "Flight was on time, crew friendly on airport and flight. Plane was clean and sits were ok."
Cons: "The food could have been better."
Cons: "So many delays, no real info provided. When we had to stay overnight they didn’t mention it would take 4 hours to get our bags which actually never came. Airline industry sucks and deltas one of the worst."
Cons: "Not cancelling it"
Pros: "the crew did really made sure we had what we needed."
Cons: "Should have made an announcement that the 3g cellular coverage was turned on. Went on in the middle of the flight and had no idea. My phone was in the overhead bin and I thought it was off. When I landed I had an outrageous fee. Should be given a choice to use it or not."
Cons: "Good flight, on time. Service ok. Captain did a good job communicating. Nice touch with wine at dinner."
Pros: "Entertainment was fine"
Cons: "On my ticket I selected the lacto-ovo vegetarian meal and I never received it. I told the flight attendant and he said “we don’t have any more, chicken or fish”. I said “I am a vegetarian” and he gave me a tiny salad, a bread roll, and a chocolate mousse. I was very hungry as I hadn’t eaten in 9 hrs"
Cons: "Checked bag fee was expensive at $120 per bag. For the two of us bags cost $240. The plane boarded late this departed and arrived late. Otherwise a very good flight. Very comfortable, all Amenities worked, the plane was clean and the staff accommodating."
Pros: "On time"
Cons: "Food"
Pros: "flight was more than 4 hours late!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
Cons: "flight was more than 4 hours late!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
Pros: "Very on time, smooth take off and landing and friendly staff."
Cons: "Perhaps spirits offered other than just wine. And a vegetarian food option."

Pros: "Flight on time and safe Crew very pleasant"
Cons: "Cramped seating Boarding dreadfully slow"
Pros: "the food , drink and the crew"
Cons: "seats not very comfortable. plane full up"
Cons: "We booked flight several months ago and it included seating assignment, so we choose our seats. Then when we check-in they had changed them to the last row of the plane. We had received a couple of emails asking for us for option to pay for advance seating. Assume they had changed their policy and now were charging. We had a close connection at LHR and being last off, we almost missed connection. Horrible"
Cons: "The delay on the take off"
Cons: "We had to postpone our first leg from London to Lisbon by a day and then they cancelled our return flight without telling us!!! So, we were trapped in Lisbon with no flight to return home. We called them and they said, "we cancelled your tickets and only have business class seats available for you and your toddler." We said no thank you. If we were going to spend 1k on a return flight, we were going to take British Airways. TAP, never again."
Cons: "The service was below average, nobody seems to be eager to assist. The food that was offered on the flight was below expectations. The company should work on improving customer care"
Cons: "No vegetarian option The last seats mean can't lean backwards when someone in front goes backwards :("
Pros: "Crew friendliness and attention"
Cons: "They ran out of diet coke and coke zero literally right after takeoff which is a joke!"

Cons: "The uncomfortable seats ."
Pros: "I was very impressed with the Ground crew who met me off the plane and had already arranged for me to go on a later flight with Emirates. If it had been possible to let me know when I was on the first flight that my onward travel had been arranged then it would have been perfect."
Cons: "my TAP Portugal flight from Lisbon to Heathrow was so late I missed my connection to AbuDhabi."
Cons: "The lady changed my 11H seat for another seat (29B) when I claim that this is not fear , a man said to me that if I insist in this matter he will not let me in Or flight , for me this was an abuse"

Cons: "I used TAP to depart beautiful Portugal."
Pros: "Not much. Lunch"
Cons: "We paid to check the bag In and when we arrived the girl could not see this. We showed her clearly the paper then she charged ya and realised she had made a mistake but couldn't refund us. Terrible experience. Don't use the."
Pros: "The plane was really comfortable and clean with plenty of legroom, and the staff friendly."
