Pros: "Overall is perfect"

Pros: "Fast and easy."
Cons: "The new Istanbul airport is way too big and confusing. Its pretty but needs people improvement."

Pros: "I did not like anything from this trip. I just learned my lesson not to travel with turkish airlines ever again."
Cons: "flight was canceled from previous flight so we had to overnight in istambul and the whole situation was handled very poorly nobody took the time to explain to me what to do and mind this I was traveling with three year old and I found myself crying at midnight at the airport not knowing what to do."

Cons: "Boarding took longer time Than it should."

Cons: "Change the mousse flavor, please. The hummus was terrible."

Cons: "I like everything. I know most countries dont like turks. But turkish are best nationality. With big hearts."

Pros: "Entertainment"
Cons: "Plane was hot on the flight going TK 6. Flight on the way back TK 5 was much better."

Cons: "Turkish Airline lost one of my checked in bag! Never found it!"

Pros: "Organized overall"
Cons: "Cabin way too cold"

Pros: "nothing"
Cons: "was unable to upgrade tickets in advance off of web site. Others in Greece and Italy tried to assist as well and found same and when calling 800 numbers the calls were not going thru or hold time was overly extreme. Was told at Athens check in to upgrade in Instanbul and to go to transfer desk to get upgrade. An upgrade of $1200.00 Euro's is extreme Being packed like sardines for a 10 plus hour flight is not good. It is also unhealthy. Turkish Airlines should consider something other then the 777 for any international flying."

Pros: "everything"
Cons: "i liked everything"

Pros: "Same."
Cons: "Same"

Cons: "The process to get into the plane at Istambul was horrendous. It took forever to process the passengers."

Cons: "This was the worst I have ever experienced. My flight arrived into Istanbul and 45 minutes until the departure I was told it had already left. I later found out something very similar had happened to a man from London, a couple from Boston, three people from Ghana, and many more that were taken advantage of in an attempt to sell tickets for them to go home. Never in my life have I seen such corruption first hand in a business that claims to be professional. I travel with them roughly twice a year so I'm not really a huge spender when it comes to their service, however I have suggested many to use their airlines. Never again will I make this mistake, and never again will I fly with them. I think I would rather spend the few extra hundred dollars than to have to experience that again. Turkish airlines you have lost my service and my respect."

Pros: "The food and quality of the flight was incredible."
Cons: "The boarding process was chaotic, partly due to the airport layout, however it would be great if they were able to sort a less chaotic way to transport business class passengers out to the jets in less cramped busses."

Cons: "They cancelled my returning flight WITHOUT me knowing and expecting me to pay for the penalty fee for misisng the first flight even tho I DID not cancel the returning flight which obviously I was gonna take. The staff was RUDE and INSENSITIVE. Qatar was better in overall customer service. Worst customer service from Turkish airline."

Pros: "Turkish A/L always professional and efficient."
Cons: "Unmanaged two-year olds crying throughout the 10-hour flight. Will avoid IST going forward as well. Chaotic airport with little or no management present. Had to wait through SIX separate lines for a simple flight transfer. Had the body scans TWICE. Ridiculous. Nearly missed my 10-hour flight to Chicago."

Pros: "The meals and in flight entertainment"
Cons: "The seating I needed more leg room"

Pros: "I really enjoyed the food and the entertainment. this was the best international flight I have taken so far."
Cons: "check in time was to long."

Pros: "The security checks to board the plane were extensive and there was potential for the situation to be very stressful, but the personnel handled themselves very well under the pressure and stayed calm."

Cons: "Security lines for US departure way too long. Turkish Airline needs more people to speed up process."

Pros: "The flight was great. It was before the flight that was highly stressful"
Cons: "Boarding procedures in Istanbul were terrible. No communication. Lots of anxiety and stress. Running through airports."

Cons: "On our way back to US, we were kept in a small area with no air conditioner for one hour."

Pros: "bad !!!"
Cons: "All !!"

Pros: "Did a very good job of efficiently, securely dealing with US requirement of no laptops, no tablets allowed on flights from Middle East."

Pros: "The up to date and *free movie options"

Pros: "pleasant flight attendants"

Pros: "Movies"

Pros: "Excellent!"

Pros: "I would love to fly with them again"

Cons: "I could not figure out how to get a vegetarian meal."

Pros: "as above"
Cons: "as above"

Cons: "I stayed in Istanbul Airport for 16 hours with no hotel or even a meal."

Pros: "I didnt receive my baggage."

Pros: "\"
Cons: "The amount of security we had to deal with. I was searched 3 times and they decided to confiscate my laptop since the battery charger was dead."

Pros: "Turkish Air has some of the best flight attendants in the business. The food is essentially gourmet (hot wrap, in this case), and the pilots are highly skilled."
Cons: "I tend to need the climate control to be on the cooler side, and 777's seem to run hot. Since there are no air vents, the warmth can be overwhelming. Also, the comments about leg-room, ... correct. I'm 6' 3" and 'uncomfortable' sums it up pretty well. For 10½ hours, being crammed into that small a space can be quite daunting."

Pros: "Great Food, adequate seating, helpful staff, efficient boarding"
Cons: "The airplane was a really warm temperature when we boarded."

Pros: "I liked the friendly staff and regular drink, hot wash cloth, and food."
Cons: "Bringing a hot wash cloth around just before landing after flying all night would be refreshing. I think it would give people the next best thing to a hot shower. I should have picked an isle seat. I was on a 10 plus hour flight and felt trapped and my isle guy had his headphones in or slept all but one small break in that 11 hours. I felt abit claustrophobic."

Pros: "Lending was excellent"

Cons: "2 hour departure delay."

Cons: "I didn't received my luggage same day Ithat was not find it and I had to wait 4 days to get it"

Pros: "The flights attending."
Cons: "The waiting time for next flight."

Cons: "My seat was terribly uncomfortable. The airplane temprature was really low that it made me so sick. I had a missing luggage where i did not hear any updates from Turkish Airlines for 5 days. I ALWAYS fly Turkish Airline internationally when going to Turkey. But after my last experience, i am not so sure"

Pros: "Everything operated fairly smoothly on the flight. Service was very good."
Cons: "Boarding was haphazard, no use of group numbers. They ran out of one selection for dinner less than halfway through the plane. My entertainment screen froze about 2 hours into the 9 hour flight and they couldn't/didn't reset it though I asked several times, so I read a book instead. I will say this was the exception flight out of the other 3 I have had with Turkish. On those, I encountered no issues."

Pros: "Plane was clean. Good food, nice details. Nice variety of entertainment."
Cons: "Entertainment system stopped working with about 2.5 hours left in flight."

Pros: "Best long distance airline I have flown to date."

Pros: "Loved the food!"
Cons: "Although I had a book and good seat-mate, the movie screens stopped working after a few minutes for about 80% of us on the flight. That made for a very long 11 hr flight. There was no apology made to those of us with broken screens. and for boarding, the Airport screens when from no gate to "GO TO GATE" and we all rushed there, some of us 2 hrs early. They put us through security where we were stuck with no available restrooms for nearly 2 hrs before our flight. There was no reason for the rush, and there really should have been bathrooms for us."

Pros: "New planes, very modern fit-out, industry leading entertainment system. Excellent flight all round."

Pros: "Flight on time and pretty smooth. Plane was nice."
Cons: "Same documents were checked several times. Kids screaming most of flight. I know that is not crews fault. Could not eat food due to food allergies. Very hungry and tired at end of flight. Legs swelled up very large. Good idea to remind passengers to move feet around every hour. But...overall the flight was nice. Good plane. Good movies. Would fly Your airline again. Will just bring my own food and move around more."

Cons: "Everything was great and went smoothly."

Pros: "My favorite airline to travel from Denver to Puerto Rico, round trip, and in Atlanta I will make the stopover, I also feel so safer to travel with my cat ... they are the best airline in everything"
Cons: "Let people who travel with pets earn extra points for taking them with Delta"

Cons: "Broken tray table literally off its hinges and unusable."

Pros: "Plenty of room and everything was on time!"

Pros: "There was plenty of space, good entertainment, it boarded fast, took off on time, and had zero issues."

Pros: "Crew was professional and understanding/empathetic given the circumstances. We were delayed 4 hrs."
Cons: "While the weather delay was out of everyone’s control and it was obvious the pilot was doing everything he could to get the pale airborne... i feel their could have been better communication from the ground as to our take off time. They kept changing our time and thus we were trapped on the tarmac for 4 hrs. Had we known, some of us could have gotten off the plane and rerouted so as not to miss our connecting flight. We and others were stuck in Atlanta, had t okay for a hotel....and missed a day of vacation....☹️"

Cons: "Lost my bags"

Pros: "Got here early!"

Pros: "Crew was friendly and efficient."

Pros: "Great crew, early arrival"
Cons: "Old screens, snacks getting smaller, too much ice in the drinks"

Pros: "Like the pleasantries from the Delta crew"
Cons: "More snacks :) !!!!"

Cons: "Delta is top notch!"

Pros: "Nothing exceptional stands out"
Cons: "Flight was not on time"

Cons: "Both Copenhagen and New York need to go a better job on the flow of passengers through Passport control."

Pros: "Flight attendants thank SkyMiles members by name at some point during the trip, very friendly."

Cons: "Terrible"

Cons: "Choice of healthier snack"

Cons: "More comfortable seats!!!"

Pros: "It was Ok. Some short delay but over all not too bad. Just didn't like the fact I always get seats next to the toilet"

Pros: "see above"

Pros: "Got to London on-time (early, actually) and safely. The in flight meal was okay. The leg room in comfort plus was great, the mobile app was awesome, and the staff (check-in, gate, cabin and flight deck) were professional and friendly all around."
Cons: "The leg room was great, but as a broad-shouldered guy, the width of the seat was miserable. Unfortunately, the Delta 767 doesn't offer any upgrade for a wider seat beyond Delta One, and my employer won't spring for that. Too bad there isn't a premium economy option. Also, the entertainment unit in the seat next to mine malfunctioned, which you wouldn't think would impact me that much except that because it was "seeing" touches randomly throughout the flight, the screen would turn on, off, brighter, dimmer, play random stuff, and just generally be as annoying as possible to everyone nearby throughout an overnight flight."

Pros: "Food was good and so was the movie selection"
Cons: "Boarding was slow and the interviewers were disrespectful. Also I was upgraded last minute and I could never understand the system by which upgrades to first class are granted. Just because I used my points to buy the flight I wasn’t eligible for an upgrade to the one seat left in first class even though the flight is full and I am the first one on comfort+ upgrade list and there was no one on delta one upgrade list."

Pros: "Everything except the time of arrival."
Cons: "It was SO late; like 3 hours late."

Cons: "No individual TV. That’s hard with two little ones."

Pros: "Crew was great"
Cons: "No entertainment on flight. No smoking in Minneapolis airport"

Pros: "great crew, very nice and helpful often looking for ways to serve people. More leg room. I had a free upgrade to exit row seating. Food was prettu good for a flight of that length."

Pros: "The food that was served was good. The crew was attentive and nice ."
Cons: "Comfort seats didn’t seem like much different than reg seats. Didn’t like the cattle call boarding process at lax ."

Cons: "Flight delayed 2 hrs"

Pros: "After almost every airline cancelled. Delta still took me to where I needed to go with not one single problem. That pilot was amazing. I forget his name. But the plane didn't slide or anything during take off. Amazing."
Cons: "What was there not to like. We were a little bit late but I wasn't in a rush. I planned well ahead. Delta moved my flight from 10 a.m. to 6 a.m. and that was perfectly fine with me."

Pros: "Flight was fine. They were especially generous with the snacks."
Cons: "My one complaint is the bathroom layout of the A320. Two tiny closet bathrooms in the back for all of coach and a much larger one much larger one first class (which is like 5 rows with a mesh curtain for separation). The coach bathrooms are so small a normal person can barely get in and turn around to close the door. I question whether a larger person would be able to actually use them. I also saw the flight attendant actively turn away coach passengers trying to use the first class bathroom when it was open (not standing in the aisle or anything annoying like that). That's ridiculous to have 2 tiny bathrooms for all of coach and also to make people walk all the way to the back of the plane when you are seated much closer to the first class bathroom."

Pros: "The service was good"
Cons: "The flight was very rough on landing"

Pros: "Crew was good"
Cons: "Flight was delayed 4 plus hours. Found out about delay from email update vice crew at airport."

Pros: "I got upgraded to comfort + which was great. quick flight, was even early"

Pros: "Was initially hoping to fly a US airline but will now look for Aeromexico first. Exceeded my expectations!"
Cons: "The layover in Mexico City was a bit long and the airport was not so great"

Pros: "Direct flight"

Pros: "Boarding, checking in etc. The usual stuff, nothign spectacular."
Cons: "Seats are getting too crowded!"

Pros: "The crew was beyond friendly and courteous. Lots of leg room."
Cons: "I was an older plane, it was louder than our flight down to Atlanta. Nothing they could do about it, but a slight annoyance."

Cons: "Excellent service excellent pilot"

Pros: "Friendly and informative flight attendants kept the passengers in reasonable spirit."
Cons: "Left nearly an hour late after confusion related to oversold seats and upgrades. The gate agent entered the plane multiple times. The landing was rough, the brakes were loud."

Pros: "Great meal in economy. Delta entertainment was free and very comprehensive. Plane was packed, but service was great."

Pros: "Entertainment was great. Many options"
Cons: "When we arrived for check in we were told we did not have seats assigned, even though I had picked seats previously. At the gate we were told the flight was very full so we would not be able to sit together."

Pros: "The crew was friendly and accommodating, and service was good"
Cons: "I purchased a basic economy ticket and upon checking in, my Delta app said my seat was unassigned and I had to get my boarding pass at the airport. I checked back later and the app had me as number 7 on the standby list. I called Delta (wait time 3+ hours... my flight was in 3), and then the Delta app support where I was able to get through to someone. She told me that the ticket I purchased over a month in advance did not guarantee me a seat on the plane (???). She said that if I was bumped from the flight they would reschedule me for the next morning. She was pretty rude and made it seem like I had a 50/50 shot of getting on this plane. I rushed to the airport in hopes that I would be the first from Standby there, and the gate agent told me that I was fine and would board right after first class and be assigned a seat then. Great. Once I got my seat assignment, I board to find out there is someone else sitting in my seat...... They eventually called the desk and had her moved, but it was the weirdest boarding experience I've had.. and I've flown Spirit. These planes that Delta fly's are SO OLD. Both times I have flown Delta the "turbulence" has been so bad and cold air was blowing right on my the whole flight with no option to turn it off (it wasn't from one of the vents, but from the side). Someone close to me works for Delta and I know for a fact that some of their engines blow mid-flight.. and they tell the passengers that it's turbulence.. so that doesn't make me feel very safe. I won't fly Delta again if there is another comparable option."

Pros: "The crew is always great. I liked the environment was cooler. It doesn't need to be refrigerator cold but keeping things on the cooler side is helpful."
Cons: "The boarding process is always horrible. Folks crowd the gate before their class is called. It creates anxiety and edginess. Never a good way to start a trip. While it always goes relatively quickly I feel it should be more organized and folks made to follow a system. Cramming right up against the ticket counter doesn't do anyone any good."

Pros: "Free rebooking"

Pros: "Flight attendants were very nice"
Cons: "Overbooking flights"

Cons: "Flight attendants were a little snobby and didn't treat all passengers equally, in my humble opinion (note: I was sitting in 1st class)."

Pros: "Arrived early. Helpful staff. Brough food and refreshments fast"
Cons: "Narrow seats in economy comfort"

Cons: "Not a lot of leg room"

Pros: "Always have great experience with Delta flight attendants and staff. The entertainment on mobile phone was a really nice add-on, I had never seen before."
Cons: "Flight was delayed in taking off, waiting for connecting passengers. Plane was old, which is most Delta planes, but this one showed it. The tray table looked like it was from the 70s or 80s. Flying into Midway instead of O'hare was anticlimactic."

Pros: "We are generally disappointed with the service on US airlines. The international leg of this trip was impressive. Great service, nice attitude, quick with food service, decent wine and beer, etc. We fly international a few times a year and after this experience we'll go Delta again."

Cons: "Very cramped seating, the 5 hour layover in Frankfort was rough, When we landed after 9 hours I wanted to use the restroom and the stewardess said we had to exit the plane immediately"

Pros: "They hand out wine like it's candy"
Cons: "Also, they hand out wine like it's candy - be careful!"

Pros: "Got to the destination"
Cons: "Everything"

Pros: "n"
Cons: "n"

Pros: "The on-board staff were excellent. Please congratulate Lufthansa on another job well done! Very good at listening and very attentive to passenger needs and passenger comfort. Bravo!"

Cons: "My seat was assigned to someone else and I paid for an upgrade but got a center seat with less legroom than what I paid for"

Pros: "The checkin was very helpful although also frstrated because they could not print the boarding pass."

Pros: "Last year I flew Air France. Lufthansa is far superior!"

Cons: "No boarding advantages as a star alliance silver member."

Cons: "Didn't happen. Missed it and got re routed thru United."

Cons: "Broken chair would not stay reclined. TV screens need to be updated. The touch feature only works half the time. You have to keep tapping it. Temperature on the plane goes from freezing to hot. Very uncomfortable."

Cons: "coach seating sold as biz class"

Cons: "A disaster but was able to arrive 5 hours later to my destination. Better than a day late."

Pros: "The stewardess who served drinks and snacks were kind, fast, and efficient."

Cons: "The plane boarded late and arrived late so we almost missed our connection."

Pros: "On time"

Cons: "No Tetris game"

Cons: "I had paid for an upgrade to sit in the front of the cabin with extra legroom (row 14A). When I boarded a man sat it my seat. He had not paid for the upgrade, but the crew let him stay in my seat. I had asked him to social distance but he continued to sit right behind me bo matter which seat I moved to. He argued with the crew until they gave up and let him stay. They did not check his boarding pass or ask him to move to his assigned seat I found a different seat away from him but I don’t see the point in paying for extra legroom when the crew let’s people who haven’t paid for it sit it those seats. I felt harassed by the man and was very uncomfortable the whole flight. I am considering my next step, I think I should at least receive a refund for the upgrade I paid for."

Cons: "Food can be better"

Pros: "Information sharing by pilots and crew. Economy class leg room is good."
Cons: "All good up to the level"

Pros: "The crew tried to be helpful but were equally frustrated with the ground crew."

My daughter and my KLM approved baggage were taken by the boarding crew while allowing other passengers to go with more than allowed"

Cons: "They left my bag off the plane. Ridiculous."

Cons: "Pay attention to passengers."

Pros: "One crew member was very good but all were not very available or checking on people. I had a seat that I purchased and it was very hard to recline I only found out that it did if fact recline it the last hour to hour and a half of the trip! It was a difficult push back to get it to recline"
Cons: "If I knew how to recline my seat earlier. I did try several times"

Pros: "quick/efficient boarding - good staff - good food - easy flight !"

Cons: "Evening snack was not the greatest breakfast was pretty food"

Pros: "Comfort was better than on the previous Dash-8. Food was OK."

Cons: "Nothing"

Pros: "Great"
Cons: "Great"

Pros: "Arrived Early!"
Cons: "Left Late :-)"

Pros: "expedited check in with nice staff. Security staff were pleasant, and the entire check in process for everything was easy"
Cons: "there was no lounge close to our departure gate"

Pros: "Overall everything was ok."
Cons: "Not that I cared at the time but having been asked for a rating on “entertainment” - there was none. Cheap and cheerful really. No extras over the likes of RyanAir."

Cons: "Delay can occur sometimes but it wiuld be better to be explained its reason and the estimated time for boarding. The customer service at CDG airport was the worst ever and all people standing boarding desk were useless without any mind what they are doing."

Pros: "Fabulous trip with friendly, helpful staff"
Cons: "Nothing"

Pros: "Due to lightening bolt strike our pre-Y2K era plane got switched out with a newer plane with modern media delivery at the seats."
Cons: "This caused a two hour delay in boarding and another 30 minutes on the JFK T4 tarmac. Same crappy headphones so it wasn’t the"

Pros: "All cabin crew were courteous. Refreshments were light. Check stuff were helpful, they did devise that the flight was full and due to space hand luggage would prefer to be put in hold free of charge. We did not have any problem with this. Plane was clean."

Pros: "Lovely staff, good food, great movies."

Pros: "Nice seats, comfortable."
Cons: "Again, no aisle seat for SkyTeam Gold member. Also, my baggage was lost. First bag arrived a day late, second after I had left Billund and it was six days before the bag with my clothes reached me. I was told I will have 100 euro credit for clothing, but in the winter and for 6 days, this was not even close to the amount I needed for clothing and necessities, to have my time here."

Pros: "The food and the punctuality"
Cons: "The technology in interteiment is not touch screen"

Cons: "KLM crews look unhappy with their work. Everything they do is a favor not duty."

Pros: "Equally friendly crew and experience. It was complimented by the time we got to spend in the fantastic KLM lounge while we waited for the flight."
Cons: "Nothing!"

Cons: "KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Also, really tired of the fake business class on these flights..."

Pros: "The crew service is impeccable. Ground services very friendly and professional."
Cons: "The seats are very uncomfortable. The individual screens are simply outdated like you basically will damage your eyes looking at them. No chargers for phones."

Pros: "On time."
Cons: "No negative"

Pros: "They were awesome."

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: "Loved this 747! Crew was professional and food was very good."
Cons: "We had a long wait (25 minutes) at the gate because we were early."

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

Pros: "It was a short flight so it was O.K."
Cons: "Boarding was odd. Go to airport early and counters were not open, did on line check in so was able to avoid the self check in at airport. Also self check in luggage seems confusing with no ground crew to help. It didn't affect me but lots of confused passenger."

Pros: "delayed"

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

Pros: "KLM food and service are great"

Pros: "Almost missed flight due to line at customs and having to pick up suitcase and check in again, they did wait for me though"

Pros: "Services were appropriate for the time of departure and length of the flight."
Cons: "Nothing really"

Pros: "I've flown SAS a few times and have always been favorably impressed with the service. On this flight we booked the "bare bones" fare and paid extra for checked bags and extra-legroom seats. The overall cost was still better than most other airlines."

Pros: "The crew was fine. The seats in the A330 are the worst only to be made worse by NO legroom. Very uncomfortable airplane. The flight crew also closes the rear bathroom off during most of the flight, I am assuming so they can use...."

Pros: "The crew was nice and the food was good."
Cons: "More entertainment options"

Pros: "The crew was truly kind and accommodating."
Cons: "The food wasn’t very good. I purchased the WiFi and it was TERRIBLE. I had work projects I was hoping to complete on the trip and I could barely get anything to load beyond email. Total waste of money and effort."

Pros: "Plenty of room on this flight. The plane was about half full."
Cons: "Everyone's breakfast was supposed to be an "egg and bacon" flavored wrap of some sort, but there was absolutely no egg or bacon flavor associated with it. The flavor of bacon is very distinctive. This thing's flavor and texture suggested some sort of very tasteless doughy material, with certainly nothing tasting like egg or bacon inside of it. Ugh."

Cons: "Service was great"

Cons: "The flight was over 2 hours late leaving Copenhagen, and then we sat at the gate while they unloaded bags to find the luggage of some passengers who decided not to be on that flight. Then it was total chaos at O'Hare. Very few SAS ticket agents who were not prepared to deal with the many passengers who had missed connections. We spent the night on hard chairs in the airport when we could have been re-booked on a flight out that night if they had been at all organized and efficient."

Pros: "On time."
Cons: "The cabin crew was detached, and curt."

Pros: "Movie selection, warm buns,"
Cons: "no thing to report"

Pros: "A lot of leg room"
Cons: "No snack served before dinner, no choice of dinner food. over see flight and the only food is dinner??? My laggage had priority tag but got out last and in resolt of it I missed the connecting flight to Boston!!! Damaged laggage"

Cons: "Delayed flight, missed connection, lost baggage."

Pros: "Excellent service and food."

Pros: "Nothing"
Cons: "We will never fly SAS again, it was a horrible experience"

Cons: "Old screens and poor movies selection, tight leg space, not really offered much to drink."

Cons: "Tried to call sas , no phone answered after 730 in Copenhagen, forced to buy my own ticket to leave early am as their incompetent sas transfer desk couldn’t find me a flight in am yet I was able on kayak.com. They refused to pay for it."

Pros: "Food, crew, overall comfort, movies"
Cons: "The plane was quite warm. We definitely could have used more water as well."

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

Pros: "Quite a contrast between international and domestic flights. SAS had a blanket, pillow, water bottle, and earbuds on each seat. We were served TWO meals including a full dinner. Flight crew was very polite and responsive."

Pros: "Cannot think of anything."
Cons: "I am a road warrior and my job requires me to travel 100% of the time around the world. This was the first international flight I've been on where even small snacks such as peanuts or pretzels are for purchase only. Plus the flight attendants seem to be disorganized and in rush. I will never use SAS again."

Pros: "SAS plane, customer service and meals."

Pros: "Awesome seat with great leg room for a tall person. The whole flight went quickly and enjoyed the crew and flight"

Pros: "The movie selection"
Cons: "To be boarded and wait for more than 45 minutes inside the plane for a second pilot."

Pros: "I liked the flight staff were friendly and helpful."
Cons: "The flight was delayed an hour and I almost missed my flight to Lubbock from Chicago. I'm also waiting on my luggage that got left behind due to the time of me catching my next flight. My connection flight was with United Airlines."

Pros: "Friendly crew. First meal was good."
Cons: "Small movie selection. Second meal/snack not great. Older plane (still had ashtrays in arm rests)."

Cons: "As above."

Pros: "They came through twice with coffee and tea after meal and snack."
Cons: "Meal trays were left a bit too long."

Pros: "Great flight"

Cons: "No wifi"

Pros: "Comfortable seats."
Cons: "Entertainment center was not working for left half of plane (which included me). Crew was extremely lazy. I asked for a coffee and she told me to get up out of my chair and follow her to the back to get the coffee. Why couldnt she just bring me my coffee? My friend had the same issue, he asked for water and she had him come to the back to get it."

Pros: "The boarding process worked well."
Cons: "The crew didn't seem to care much. The entertainment systems didn't really work and the response was simply deal with it. The food was terrible. The crew did not handle the passengers at all as they were up consistently and taking stuff out of the overhead containers."

Pros: "The constant service provided by the flight crew. The food was excellent and even got a free beer. The inflight entertainment selection was abundant, did not even have to listen to my music. Very friendly crew."
Cons: "I understand coach is coach, but it was a little tight for my height."

Pros: "Entertainment"
Cons: "Food was of poor quality, one free soda on a 8.5 hr flight."

Pros: "Great food, smooth trip"
Cons: "Could use bigger movie selection"

Pros: "There was enough space for your legs, there were blankets and pillows which is nice for a long flight. The individual entertainment screen is preferable for a long flight, so you can watch a movie of your own choice."
Cons: "There were two diner options, chicken or cod, and I was just given the cod without having an option to choose."

Pros: "We were very impressed by the customer service and how comfortable our flight was. I will definitely fly with SAS again."

Pros: "Much roomier than united"

Pros: "They checked my mobility scooter at the plane door, put it underneath and brought it back up to the plane door in Chicago. WHAT service!"
Cons: "I did NOT like the fact that this was NOT true in Copenhagen. I checked my mobility scooter at the plane door, they put it underneath, but was met by a man who said he was going to take me to pick up the scooter (in the baggage claims area--after I was promised in Chicago that it would be at the plane door when I arrived in Copenhagen). Made me get in an enlarged golf cart, and took me to the "transfer area" -- where I had to get into a wheel chair -- for the rest of the journey to the baggage claim area. Then he stood there waiting for a tip that was to NEVER come!"

Pros: "Business class upgrade was very nice. Food was good and entertainment options were above par. Loved the quality of the pillows and blankets. Also loved the fresh fruit and candy snacks."
Cons: "The gate agents refused to provide my boarding pass until the entire plane had boarded already. I was one of the last people on. I wasn't given a reason for this or assured I wouldn't be put on a later flight. This caused a lot of stress during my layover."

Pros: "The food is great, the flight attendants are great, and the flight is comfortable."
Cons: "There is little legroom unless you are in first class."

Pros: "Comfortable seating in PLUS"

Cons: "The crew could ask people who does not have a rush connecting schedule to stay at seat and let those who has a rough schedule to get off first. UA did this, but SAS did not."

Pros: "The seats were comfy and the food was good. Air temperature was pleasant, not too war, or cold."
Cons: "Was no offered water during the flight. We had a bottle of water in the seat pocket but at no point during the flight were we offered additional water. I saw people get up and ask for some but when the flight is 9 hours you would think they would come by once or twice offering some. Other airlines do this and I love it. I was so thirsty when getting off the flight that I downed 2 bottles of water at the airport. They also didn't offer complimentary alcohol. Other international flights offer an alcoholic drink with your meal free of charge and I appreciate that. I have a bit of anxiety when I fly and that helps take the edge off. I was really disappointed in this. Heck, Air Berlin comes around and refills your wine glass multiple times."

Pros: "Better"

Pros: "Boarding & deplaning in Copenhagen and Amsterdam was great - fast & efficient, if not a bit chaotic. Good mix of movies to choose from during the flight, and the in-flight internet was fast and stable."
Cons: "The crew on the Chicago/Copenhagen legs were rude and curt. Food was horrible. The dates on our entres indicated that the meal was packed 10 months prior! The snack cakes that came with the meal were sickly sweet. The salads on both legs had brown leaves."

Pros: "plane interior seemed new/clean. Big TVs and lots of movies in the SAS Plus / Prem economy seats."
Cons: "The cabin crew was pretty terrible...ranging from being generally disinterested to actually actively hostile towards passengers. No wonder SAS is in such dire straights. Would never choose to fly SAS again."

Cons: "Food wasn't so great."

Cons: "Movie selections were a bit dated"

Pros: "I was switched to virgin air as a result."

Pros: "Our original flight was to be from Hannover to Copenhagen to Chicago. What we got was Hannover to Copenhagen Stockholm to Chicago. The flight team was cold and offered nothing for our inconvenience. Our meals were delayed (I feel for the diabetics on board). When we go to Chicago, an announcement came overhead thanking us for our patience. Little effort too late. There should have been a personal apology for the flight crew to every passenger. It would have cost them nothing to do this while they were passing out drinks or meals. At the very least drinks should have been comp-ed for the Copengagen to Stockholm leg of the flight. This was a bad situation, yes. But, SAS missed numerous opportunities for service recovery to ensure my future business."
Cons: "Flight crew was distant and didn't seem to appreciate what a huge inconvenience this was to people. Many people missed connecting flights. I am not diabetic but this was a horrible situation for people that have to plan and schedule their meals."

Pros: "Crew was very sweet."
Cons: "The entertainment was out of date so there were no on demand movies which is not okay for that long of a flight"
