Airline reviews

Pros: "Most of it was of a reasonable standard."
Cons: "Plane was full"

Pros: "crew was nice"
Cons: "First time flying with a partner through Delta, so they stuck us on a Virgin Atlantic flight meaning I didn't get my free Delta check in bag (a fee of $60 each way) when I have gotten it every other flight I have ever taken with them. It was also 2 whole hours late in boarding."

Cons: "Nothing"

Pros: "Great crew, comfortable and smooth flight"

Pros: "They didn't serve any refreshments or even water"

Pros: "A smoothtrip run by great staff."
Cons: "Thé food was rather stodgy overall."

Pros: "Food was delicious, consistent timely service and excellent entertainment options onboard. The flight was an hour early!"

Pros: "Amenities"
Cons: "Bed was incredibly uncomfortable in first class. It was like sleeping on the floor. People talking loudly in the bar late into the night, which made it even harder to sleep. Didn’t sleep a wink on this 10 hour flight."

Cons: "I did not like the fact that my seat was between 2 small children that belonged to a family sitting behind me .It was ridiculous to put a stranger on a 10 hour flight with a 3yrar old on one side and a 5 year old on the other"

Pros: "Staff on this flight were excellent"

Pros: "The crew and food were excellent. A little more space between seats would be appreciated. The entertainment equipment was not intuitive or easy to operate. I still feel the airline did a great job getting us to London on-time and a pleasant flight."

Cons: "Virgin Atlantic continues to give great service. Their lounges are way above all other airline lounges. It is difficult to get well prepared and fresh fish in lounges, but Virgin Atlantic knows how to do it."

Cons: "Food was hard and little stale."

Cons: "Flight was cancelled ."

Pros: "Check in was very smooth with very friendly staff. On board crew was very welcoming and service was excellent."
Cons: "Aircraft configuration of the 787-9 was very poor with 9 seats abreast making the seats very cramped and very poor leg room."

Pros: "Efficient, friendly, on-time!"

Pros: "food was good, and tvs in the seats."
Cons: "wifi didnt work, was the whole reason i took this airline. most international flights are cold it was very hot"

Pros: "Good entertainment, food and in-flight crew"
Cons: "Because this flight was delayed it was a miracle (involving running til my throat literally bled) that I made my connection. Ground crew could not have been less helpful - even to my friend who they knew was trying to get home to attend a family funeral."

Pros: "Crew"
Cons: "A plane from 1960? No entertainment center!"

Pros: "A large selection of movies, shows and music to choose from. Flight crews were attentive and friendly."
Cons: "The narrow space between each rows for passengers to move from their seats."

Pros: "Good notification re a 30 Minute delay. Obtaining board passes was a breeze and love where I can save the passes to my wallet on my mobile device. Flight crews were helpful, cheerful and professional."
Cons: "With seats being so tight causing an issue when getting in and out of seats."

Pros: "I felt that they were very thoughtful about the fact that it was a long flight. We got two small meals, which was perfect, and even a little gift bag with a sleep mask and toothbrush and such in it. These were just a couple of the many nice touches included in the flight."
Cons: "Very small quibble: the screen resolution, or maybe the contrast, of the personal video players was not so great. This was fine in most cases, but it meant I could not watch videos that had subtitles. Not a big deal but possibly worth fixing. Thanks"

Cons: "One toilet not working"

Pros: "first time I flew VirginAtlantic. Heard so many good things about it. It fact even our Uber driver was praising the airline on our way to the airport. But once onboard: - poor food (I mean 'survival kit' style) - entertainment station was not working - games feel like 20 years old - design (heavy red) now looks dated and suffocating - hostesses are more focused on their hairstyle than their customers"
Cons: "Back to Air France next time!"

Pros: "Food"
Cons: "Seat reclining happens even during meal time and landing! I had to ask crew to get passenger in front to put seat back upright during meal time!!! Crew should've noticed themselves and ask the passenger without my prompting!! So annoyed!! I complained to VA too"

Pros: "The food was surprisingly ok and the seats in PE were comfortable, plus there were two USB ports, perfect!"
Cons: "Being woken up to be asked if I wanted to eat, twice! If I wanted to eat, I wouldn't have a sleeping mask on my face, or be asleep! Plus, upper class and premium economy didn't board first."

Pros: "They were were very kind and helpful to all passengers"

Pros: "Genuinely pleasant cabin crew, good service, good food."
Cons: "Virgin Upper Class seats are cramped, with very limited stowage space. Turning the seat into a lay flat bed (and returning it seat at the end of the flight) takes some effort--not the simplest of processes. I'm not tall, but my feet protruded into the aisle so I was being disturbed whilst sleeping. Seat is also quite narrow--feels quite claustrophobic when sleeping."

Pros: "Still a more pleasant experience than BA but others have overtaken. Crew make a difference though."
Cons: "Limo service wasn't great in China - asked for address of hotel - a major international chain and confusion on booking details"

Pros: "The boarding and the overall flight experience was quite good."
Cons: "There were movie options such as Sully and Deepwater Horizon, which I think are unsuitable for flights. Overall, the movie options could have had more variety."

Pros: "Smiling and helpful staff Great FREE food and drinks good movies Free goodie bag of travel goods, blanket, pillow etc Free candy for landing descent"
Cons: "Leg room is a little tight"

Pros: "First off,the staff is awesome. From the check in people to the flight attendants .... The entertainment was up to date and the safety video was awesome.. Great conditions for economy class.good leg room...I give them a 5 star rating ... I only wish they would do more flights to other countries overseas ..."
Cons: "I can't think of anything I didn't like"

Pros: "The crew,food and entertainment the food has improved, the ground and flight staffs was very pleasant and helpful"
Cons: "We were flying to Miami, then into a cruise,weighs restrictions,we were find a100 dollars for a couple more kg, we were on holiday for nearly three weeks"

Cons: "Crew"

Pros: "The crew left my breakfast in the sear next to me because I was asleep (unfortunately i didn't notice till I started to disembark...)"
Cons: "I couldn't get comfortable enough to sleep very well, even though I was in a window seat (which I can normally lean on)."

Pros: "Friendly crew and good food"
Cons: "Nothing"

Pros: "Everything except the plane itself"
Cons: "Plane cramped"

Pros: "Everything was great ! The staff very nice and the plane is absolutely amazing .."
Cons: "We paid for extra leg but there was no difference between normal and extra .."

Pros: "Mostly everything was fine."
Cons: "Not really anything particularly that I didn't like."

Pros: "I loved wine and whiskey. Blanket and blindfolds, headphones helped me sleep. Care packet with toothbrush came in handy."
Cons: "The Sears were tight and thin. I felt pushes from behind. I could not recline the seat enough. I didn't get a window seat, which is my favorite."

Pros: "We were late arriving at the airport and the checkin desk people were SO nice putting us through. Otherwise we never would have made it on the flight. Also the extra legroom seats were well worth it!"
Cons: "Nothing!"

Pros: "There were lots of choices of movies. The flight was only half full, so I got two seats together to stretch out."
Cons: "The cups for water and juice were very small."

Pros: "At JFK the lounge and service was the best I have encountered."

Pros: "nothing"
Cons: "My ticket was cancelled at the time I was standing in front of the airline counter to check my bag. I was so furious. The airline did not help me at ALL. In fact, they offer me to buy a brand new ticket at a new price!!!!!! I ended up re-bought the ticket from United airline as my husband has United card (chase) and we ended up paying over 1900 for the ticket that should have been about $911. The priceline number is not helping. I have trip insurance but no. nothing worked. I will never fly Virgin Atlantic again."

Pros: "Very attentive and friendly crew! The plane was nice and clean, nice purple tinted lights. They served us plenty of complementary meals, snacks, mints and drinks. The in flight entertainment was the best I've seen yet: movies, tv, music, games, all recent and easy to use. We will definitely fly Virgin Atlantic again!"

Pros: "Having partied until 6am for New Years I was grateful for a bed on the flight home! Fantastic crew, planes and overall service!"
Cons: "Wish the arrivals lounge was open for flights arriving in the afternoon."

Pros: "Everything."
Cons: "I think James Bond movies would be appropriate."

Cons: "My luggage didn't arrive at my destination until 2 days after I did. And after I checked my luggage, a leather satchel was stolen from my suitcase. I reported the theft to Virgin Atlantic and requested a report nearly a week ago and have heard nothing back. I am usually careful about packing luggage, and did not think the leather satchel would attract a thief working for the airline, but I will not make that mistake again! DO NOT TRUST VIRGIN TO HANDLE LUGGAGE."

Pros: "Attentive, friendly crew"
Cons: "Delay, small seats"

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: "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"

Pros: "Excellent and professional crew members"
Cons: "Nothing, the flight was smooth, most enjoyable"

Cons: "The food offering"

Pros: "The crew was amazing but delays upto 2 hrs"
Cons: "Nothing as not in control"

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: "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."

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"

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

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."

Cons: "They only offered tea and coffee for free as a drink and nothing anything more, and were not kind at explaining this."

Pros: "Crew were excellent, had a row to myself, luggage turned up quickly"
Cons: "No landing cards given!"

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: "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."

Pros: "Great!"

Pros: "boarding is different and they were talking over pa announcements at heathrow so you could not hear what to do. you go through one ticket agent to the down stairs to another ticket agent. everyone knowing what to expect crowded around the second ticket agent and there because of that forget about boarding by row or zone you couldn't get throught the crowd. plus the second ticket agent was right next to the downstairs escalator so people coming late got on before us."

Pros: "The food was very good surprisingly"
Cons: "Again the seats are too tight and they should not be allowed to recline"

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

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

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

Pros: "Comfy and good movies!"

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: "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."

Cons: "I asked for water and was given half a cup, when I requested they fill the cup they said if I wanted more I had to buy it. In addition, when we left the plane everyone pushed their way off instead of following the order of the rows."

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

Cons: "Finnair are hellbent on trying to sell goods and continuously interrupt the movies with their confounded announcements every 15 minutes very annoying. If i wanted to buy something its in their mag and as a regional flight it should include some form of nourishment other than juice or coffee one off, tight fisted and not a descent selection of food either"

Pros: "Speed boarding process."
Cons: "No entertainment system on a 3 hour flight..."

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: "Service, staff, food and beverages all excellent"
Cons: "Seat was just a little hard when lying on my side"

Pros: "Everything went smoothly"

Pros: "Arrived ahead of time Crue"
Cons: "Sales on board"

Pros: "The accommodations made me feel like I was in first class!"
Cons: "The screaming child behind me ):"

Pros: "Excellent"

Pros: "Breakfast was good"
Cons: "Air conditioning was blasting down on me too powerfully"

Pros: "Food was good for airplane food."
Cons: "Plane only had screens for the movie in the center aisle and only every five rows or so."

Pros: "British airways offers amazing entertainment selections on the Screens over 25, food was good"
Cons: "Check in line was terrible, I had checked in online but still waited over a hour to bag drop, service was not great either the flight attendants were not happy at thier job.."

Cons: "I sat in the window seat. Trying to get out of the row is very difficult. The arm rests do not rise high enough to get around without needing to climb over them."

Pros: "Nothing!!"

Pros: "Good flight, really good new A380 aircraft, smooth nearly all the way, usual small seating space as on All airlines"
Cons: "Routine airline food."

Pros: "the price was very good"

Pros: "Good"
Cons: "Breakfast"

Cons: "Experienced very rude cabin crew"

Pros: "Having read horror stories online about booking with Kayak's partner Justfly, I was prepared for the worst (last-minute cancellations, partial refunds, all-around crummy service). Actually, my Finnair flight was great - it was operated by BA, so it was a nice new double-decker Airbus plane. It was maybe 3/4ths full, so I nearly had a row to myself - shoutout to the jerk who decided he was entitled to the aisle seat. The flight was smooth and easy and best of all, it cost a fraction of what the BA price for a one-way from SFO to LHR cost."
Cons: "The food on BA continues to be meh, but what most people don't realize is that ALL airline food is meh, because your tastebuds don't work properly 30k feet in the air (it's a scientific fact)."

Pros: "Movies Food Comfortable seating"
Cons: "Going through security"

Pros: "It was relatively inexpensive. I didn't mind the food/"
Cons: "This flight was operated by BA. Seats were incredibly uncomfortable. When the guy in front of me reclined his head was practically in my lap. TV's were crappy and the in-flight selection was mediocre. In flights announcements were very loud through headphones."

Pros: "The energy of the crew was upbeat despite the lock of enertainment they tried their best by accommodating my various wishes."
Cons: "They were no snacks available except the ones that we had to pay for - which in fact I thought was a bit pretentious towards the passengers."

Pros: "It was not Finnair it was all British airways."

Cons: "BA lost my baggage. The sandwich they offered was uneatable. Marshall Hoffman"

Pros: "Crew, boarding, cleanliness of the plan, and all other aspects other than food were good/excellent."
Cons: "The vegetables in the meal / salad were still frozen….inedible. In the morning in the asian vegetarian meal it was simply fruit…that was it. No protein source. I have been on many BA flights and the food has not been this poor, so not sure if the carrier who services food source has changed."

Cons: "Need wifi to work. Highly dissapointed that BRITISH air doesn't have this feature. Most airlines do!!"

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

Pros: "Checking and boarding was lighting fast"
Cons: "There was a bit of a delay, which was due to weather and certainly not their fault. They kept us informed"

Pros: "I last traveled on British Airways in May of last year (2015) and the food was beyond dreadful. Therefore I was very pleasantly surprised that there has been a huge improvement. They were very generous with the drinks and the food was plentiful and quite a reasonable standard for airline food (they gave two full meals from San Francisco to London, whereas most airlines give one meal and one snack on that route). They actually checked us in on the earlier side, we took off very promptly and got to London early. It was nice to be on time for a change - so often I find airlines run a bit late. Staff were all pleasant and helpful. Pilot's messages were pleasant, friendly and even a bit informative."
Cons: "Web check-in ahead of time was a total disaster. I got an email telling me I could check in 36 hours early and "secure a good seat" but neither of the 2 sets of codes they provided in the email would work because it was all about Finnair but actually the flight was being run by British Airways. I spent about 30 minutes on the 'phone trying to get the appropriate sequence of numbers and letters to enter so as to check in and get a good seat - still nothing worked. This was at 5:45am - I regretted the time spent when I could have gone back to sleep. My daughter later spent a further 90 minutes trying to figure it out, only to be told finally that our only option was to get to the airport early and check n there which was what we did. It was beyond irksome. Please note, if the airline actually flying is different fro the booking airline, the locator number for check n will be DIFFERENT and needs to be provided to the customer to avoid a great deal of hassle and confusion. We gt particularly unlucky because BA computers had a glitch that day but the general point still stands."

Pros: "For once the seats have enough space. Airlines think we are cattle and that they can pack as much as possible every airplane. For once I was glad to have a confortable experience."

Cons: "Our bag was not checked through to our final destination and was delivered a day later."

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

Pros: "easy - no surprises"

Pros: "Flight was half empty, room to spread out"

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

Cons: "Entertainment system is very old, but have a good selection."

Pros: "I have a BA - Gold card- BA lounge was good."
Cons: "Comfort- Plans are Old, Entertainments is Worst. BAD BAD BAD."

Pros: "Head phone jack was not working in my seat."

Pros: "Good entertainment. Arrived on time. Unnoticeable smooth landing."
Cons: "OK. For what I paid, I am not expecting much."

Pros: "And perfectly on time!"

Pros: "Accuracy Staff Serving"
Cons: "My name was wrongly written on the passanger list."

Pros: "The configuration of the seats are really awkward. Seems very interesting at a glance, but not so nice when you have to sit in it for 10 hours. The business class seats are very narrow. I'm pretty petite so it was okay for me, but I think an average or bigger than average person would have a hard time turning at all while the seat is in lie flat position. I had a window seat which gives you more privacy as long as you have the divider up between you and the passenger next to you. You are really arm length away from each other though. And! You can't have the divider down the entire time because they serve your meals by passing it over to you across your neighbor through the divider. The divider is also required to be down during taxi, take off and landing. So, I'd imagine it to be very awkward if you're sitting next to a total stranger. You also have to straddle over someone's legs if you want to get out of your seat to the bathroom if you have window seats."

Pros: "Movie selection was excellent."
Cons: "Uncomfortable seats and tight quarters. First class was too expensive."

Pros: "First time across the Atlantic, and the British/French crew was the most polite crew ever."

Pros: "Nothing"
Cons: "Cramped, cold,"

Pros: "Very pleasant and efficient crew"
Cons: "Departing 50 minutes late. However, most of the time was made up enroute"

Pros: "Seats are snug. You get to know your neighbors really well."

Pros: "Nothing"
Cons: "If I had known when I made the reservation it was American airline would have never booked a ticket plane was dirty food terrible the whole plane needed a update"

Pros: "direct flight"
Cons: "There was a lack of air and no possibility for individual airing your seat, during our flight we had to stand in the back because we were almost passing out of overheating 30 Celsius plus heat in our row. We asked for a cooler temperature and only the last 20 minutes it started cooling but then to ice cold. My audio was not working properly, at max it was still unclear. We have had better flight experiences."

Pros: "Great staff on BA, very helpful and friendly, even going above and beyond to find me a drink I had requested. I'm not a frequent traveller these days and I enjoyed the variety of entertainment available. Flight was a few minutes early, which was a bonus."
Cons: "My headset wasn't working, luckily I had my own nearby and was able to use those."

Cons: "Seats on the Dreamliner seemed cramped and too close together."

Pros: "Nothing."
Cons: "I'm still at Heathrow 12 hours later. I never made it to Oslo."

Cons: "Food"

Cons: "Simply everything"

Pros: "Love the A380 it’s smoothness quietness and spaciousness. The experienced mature crew were excellent."
Cons: "Food quality and selection. I"

Cons: "Missing one suitcase and it will be delivered a day late supposedly"

Cons: "Club World is a super dated product. The tech is old and you are uncomfortably close to your neighbors. Also even when you buy a business class ticket British Airways makes you pay to reserve a seat in advance if you don’t have status with them. That feels over the top for a premium customer."

Cons: "BA is löst. This whole experience for a first class flight was a joke. SF no Lounge, food terrible, london lounge max BC level. LH 2x better, they need change"

Pros: "The free drinks."
Cons: "The stink of curry throughout the plane and the other choices of meal being gluten laden pasta and gluten laden crackers, muffins, and bread for breakfast. I am very glad I ate in SFO before leaving or I’d have been starving by the time e arrived in LHR."

Pros: "Boarding staff & crew were fine"
Cons: "The seats were the most uncomfortable I have ever travelled in - this plane definitely has the worst seat width, leg & reclining space that I have seen. I have been in long-range (16 hours) flights that were more comfortable than this. If anything fell on the floor, I couldn't retrieve, I couldn't sleep at all & had contorted joints & a body ache when we landed. To design such tiny seats is truly inhumane."

Pros: "No complaints at all"

Pros: "That I got to London..."
Cons: "We were stuck on the plane for two hours because of engine issues, and there is no air in coach in their planes. It was 90 degrees in there! For two hours! The other classes had air and we had none, it was a health violation for sure."

Pros: "Good entertainment."

Pros: "Arrival into Heathrow was unsatisfactory."
Cons: "Wheelchair request was ignored"

Pros: "The size of the plane"
Cons: "Leg space."

Pros: "Nice variety of movies to watch on personal screen. Friendly crew."
Cons: "Food too spicy and not British enough. Button on chair broken so unable to recline even a little on long flight. Luggage not transferred to final destination...stayed in London"

Cons: "They lost our bags. Many of us on board. And they didn’t give us tracking numbers to follow-up. Argh"

Pros: "wonderful crew, good enough food, wide entertainment, seats as good as can be expected, great plane, great flight, great crew, on time and safe and arrived in good spitrits"
Cons: "as always, rather crowded, seats rather tight,"

Pros: "I like that we didn't crash"
Cons: "They lost my and 5 other persons luggage! British Airways sucks!"

Pros: "Crew was nice. SFO-LHR was great entertainment."
Cons: "They lost my bag! I was waiting for this ski trip for a year, and they lost my snowboard bag. It is still in London and I'm at Avoriaz, waiting for a driver that god knows when will come."

Cons: "Cold coffee."

Pros: "Only one layover in London"
Cons: "Emirates, Etihad flights I thought were a bit newer and better in terms of comfort and entertainment with more charging ports etc"

Pros: "Crew were good , food was ok."
Cons: "Flight delayed again so both flights to USA and return were delayed... not a great experience . Entertainment took a cou0le of hours to sort, they had to keep resetting it"

Pros: "Courteous, helpful and on time. Good price as well."
Cons: "No complaints"

Pros: "The boarding process was smooth."
Cons: "The food was terrible."

Pros: "The crew was friendly, there was entertainment"
Cons: "Boarding was chaotic, no specific lines, etc."

Cons: "Fresh food"

Pros: "Everything"

Cons: "The screen was pretty big but quality pretty bad. Looked like 80s CRT. Also bad selection. Luckily it was a red eye flight."

Pros: "Quality service."
Cons: "Vegetarian dinner of pasta was uninteresting. The Indian meal in the other direction was much better."

Pros: "I love the bins by the side of the Airbus, and for an economy seat there was a good amount of leg room."

Pros: "Food was good. I liked that boarding And check-in went quickly."
Cons: "The pilot flew too close to a lightning storm near South Dakota. Really bad turbulence as dinner was being served. It was quite scary and my wife and I lost our appetite. Attendants were also slow to pick up our trays afterward."

Pros: "Went by quickly and efficiently."
Cons: "More music choices would have been nice."

Pros: "Nothing"
Cons: "Seats are ver very bad no good food no good Sevres"

Cons: "After taking off in San Francisco flight got re-routed to Minneapolis because of a sick passenger on board. Caused me to miss my connection in London and the subsequent flight I was put on because of the delay. Spent 10 hours overnihht at Heathrow in London because British Airways wasn't giving out hotel vouchers just £15 in meal vouchers. Disappointing."

Pros: "We nisssed it due to British airways ineptitudeeverythubg"

Pros: "Storage bins next to seat in world traveller plus"
Cons: "Lack of seinking water and no toilet in the world traveller plus cabin - curtains divided off the area blocking access to any toilets!"

Pros: "Aircraft"
Cons: "Food"

Cons: "More legroom would have been nice"

Pros: "Checking in online 24 hours prior to departure I received up-dates thrice regarding the delay of the flight which was very convenient. I had also learned about the protections that I enjoy as a passenger checking in online. The flight caught up in terms of timing as I had to catch a connecting flight to the continent from London. I was very pleased, also with the courteous flight attendents, the food, the entertainment selection and sufficient leg room in economy class. Overall a lovely experience, indeed!"

Cons: "It has been a week and British airways still hasn't delivered my suitcase."

Pros: "Easy online Check in. Nice crew."
Cons: "Very tight space on flights."

Pros: "All great"
Cons: "I liked everything"

Cons: "Seat too small. No free wifi in the XXI century? !!!"

Cons: "Could not do online checkin due to some sort of problem with their booking system, and as a result couldn't choose our seats on the long haul flight."

Pros: "Pleasant check in process. Long layover tags put on our checked bags On time"

Cons: "My bike was checked luggage and was late coming from London. It made me miss my alitali flight and had to spend the night in room."

Cons: "Wish water had been available For free London to Framkfurt"

Pros: "Everything no complaints"
Cons: "No copmplaints"

Cons: "On time and good staff"

Pros: "I upgraded my seat fr more legroom"
Cons: "On the trip over, British Air had no record of my seat upgrades. They tried to accomodate, but it was not the same. They did process a payment for about $110 for upgrades both way, however, and I have written to get a refund. In general, British Air can be not responsive or helpful in the admin department and i will avoid them from hereon."

Cons: "When you book BA and end up with Iberia, that’s definitely not what you want..."

Cons: "My checked bag did not make it to London, and it’s really affected my short stay which requires a lot of traveling around England."

Cons: "Missed my transfer in London because the plane took too long to unboard and I was unable to make it to the gates of my next flight in time, despite there being over an hour connection time. The flight came in slightly late and passports were re-inspected upon unboarding which wasted a lot of time, and Heathrow is a nightmare of an airport on a good day, which made it very difficult to get where I needed to go."

Pros: "Arriving ahead of time"
Cons: "Too hot in the plane"

Pros: "The aircraft comfort"
Cons: "Do the checking before not 15 min before the departure"

Cons: "Delayed by an hour due to inbound delay, causing a knock-on delay with plane maintenance. While fairly comfortably seated and offered water, this still was somewhat unpleasant especially after a long-haul from Havana"

Pros: "Not a lot."
Cons: "Arriving at the gate whilst the flight was still boarding, with a boarding pass in my hand, and being told that my seat had been given to someone else because the Airline unilaterally decided that my connecting flight from Bogotá would not arrive in time. Followed by two hours of Iberia staff being surly, not looking me in they eye and doing absolutely nothing about getting me home. I have now been travelling for nearly 30 hours without sleep, am stuck in Madrid with no certainty of when or how I will get home or see my luggage again, and am seriously seriously pissed off. I do accept that things can sometimes go wrong and that it is nobody’s fault. This is definitely somebody’s fault."

Pros: "Every thing was ok"
Cons: "N/A"

Pros: "The food was nice."
Cons: "There was no water in business class toilets. The staff are not polite."

Pros: "It was my first flight with Iberia - I was very pleased with the entire experience."

Cons: "I was not able to check in online"

Cons: "Tiny food. Late one hour."

Pros: "The screens on a dozen seats just failed a few hours in - engineering issue. And breakfast was a cold pretzel. Food gets let’s generous on BA all the time. The crew were lovely."
Cons: "A 2330 Flight ran significantly late with a passenger delay and then de-icing. The repeated assurances of “a 10 minute or so delay” were obviously not correct. Takeoff close to 0100 was followed by drinks AND then food - my vote would be neither. Please oh please just let us sleep."

Cons: "Seating and not so friendly"

Pros: "Heathrow Airport has a lot of stores to keep you occupied"
Cons: "Late notice of where our gate was located. By the time we got the news, we went to our gate and the people were already boarding"

Pros: "I like the staff and the generous host of them"
Cons: "The price was not matching the benefits of the ticket because it was without check in bag (luggage) and every single thing you have to pay The type of aircraft there are using its too small business class is very poor nothing to compare with other company."

Pros: "Crew was nice and I had a great flight with Iberia on my flight from Chicago to Madrid"
Cons: "I am 6 feet 180 pounds and I had absolutely no legroom was completely stuck in my seat can’t believe that a tourist class seat is this small with no legroom"

Pros: "That I arrived"
Cons: "Iberia flight was delayed by 45 minutes causing me to miss my connection from London to Dublin."

Pros: "Airbus 320"
Cons: "Boarding process and pitiful legroom space . Iberia clearly loves showing the privileged few who have paid top dollars to be at the front , that we must be made to wait and struggle to get to our seats .Then, we have to squeeze into a tiny , pitiful space of a seat .....Even Ryanair does better !"

Pros: "seat is comfort"

Cons: "I stopped at the Iberia check-in at Barajas in Madrid. They sent me to BA check-in, where I waited 45 minutes to find out that I should be at Iberia check-in. Then, Iberia check-in had to send me to last minute clerk or I would have missed my flight. Last minute check-in ended up being the same place and same clerk I began with."

Cons: "A porter checked our bags at the gate without asking us whether we were traveling beyond London, so the bags were never transferred to the transatlantic flight nor did they arrive in SF. It wasn't necessary to check them because there was plenty of room in the overhead bins when we got on the flight. We immediately asked a flight attendant to help when I realized they might not go through and he said he spoke to someone who caught and tagged the bags to go through, but it still didn't happen. It would have been easier if he had just brought them to us on the plane. Another women's bag was taken with all her baby supplies and bottles in it for a 16-hour travel day. Very frustrating for all of us."

Cons: "Mistake Kayak or its subcontractor made in listing the name of my wife incorrectly. This created a real hassle in getting a boarding pass in her name"

Pros: "Arrived on time"
Cons: "The seat pitch was so small my knees were hard against the seat in front of me for 1.5 hours and I was miserable the whole time. To put this in perspective this was the most uncomfortable I have ever been on an airplane. My legs hurt the whole flight. This was the first leg of an expensive international flight and given the price of the 2 legs I should have been upgraded to a more comfortable seat. My flight to Europe on Iberia was excellent. However based on this bad experience I plan to avoid Iberia in the future because they treat their high price paying customers poorly. Peter Valorz Valorzp@yahoo.com."

Cons: "There was no complimentary water or beverages"

Pros: "Nothing stood out."
Cons: "Late. Ineffective boarding - announcement said we would board by row, but actual boarding was by mass crowding, with no attempt by crew to improve matters. No recognition of dwindling baggage storage space meant that I had to cram my suitcase under the seat, and spend the 2.5 hour flight with my legs jammed against it."

Cons: "Upon boarding the aircraft was really hot, I was sweating in my seat... I did not receive any complementary drinks or snacks."

Pros: "Movies, no delays"
Cons: "Luggage was not documented correctly to my final destination by Iberia"

Pros: "new plane"
Cons: "nothing"

Cons: "Very limited room to move. Rather impersonal"

Pros: "Comfortable flights & on time"
Cons: "Service, flight crew seemed to busy chatting instead of serving."

Pros: "Nothing"
Cons: "They forced us to check our bags at the gate even though we had an international connection to make in London--to continue flying to Chicago. As a result, we had to go through customs and security in London, and would have most definitely missed our connecting flight back home to the States if not for a woman in customs at Heathrow who let us cut to the front of the line. I will never fly Iberia again and will be lodging a formal complaint."

Pros: "Nothing"
Cons: "No free snacks or drinks"

Pros: "Easy check in and comfortable seats"

Pros: "The ease at putting my luggage in.."
Cons: "The prices of the food and drinks!! Ripped off!!"

Pros: "Everything was delightful, definitely my best ever flight!"

Pros: "We were overall very pleased with everything about, thank you!"

Pros: "Space, meals, movie selection"
Cons: "N/A"

Pros: "The crew was fabulous! And the ride was on time and had plenty of entertainment."
Cons: "My only complaint is that the seats were very tight in the economy class. We were packed like cattle. I know these were the "cheap" seats but for almost $1500 I would hope for a bit more comfort."

Pros: "Nothing"
Cons: "Kept us waiting for five hours"

Cons: "Late departure."

Cons: "The seat did not recline, a bit ridiculous for a plane that size"

Cons: "The fight from Chicago to London was a nightmare."

Pros: "Loved the gluten free meal option."

Pros: "Spaciousness of aircraft, comfort of aircraft (vibration, noise)"

Cons: "not enough leg room. and i have to point out that I am a petite 110 lbs, 5'2" woman. although the flight is short, a complimentary snack and drink would have been nice. instead, you had to pay for anything you wanted. prices on top of that, were exaggerated. very disappointing."

Pros: "Great flight attendants."
Cons: "Plane needs wi fi and USB ports. It was a dinosaur ! Cramped seating. Expensive!"

Pros: "Good movie selection"
Cons: "VERY cramped"

Pros: "The flight from Raleigh to Heathrow London was LONG, so I especially enjoyed the wine being included without extra cost! Wine helped me to relax, read, & survive the long sleepless night!"

Pros: "The flight crew was fantastic, the flight was not crowded, and there was a decent selection of media."
