Pros: "Great crew & good complimentary food"
Cons: "More seat pitch"

Cons: "Not having to go to a different, further away airport because I missed my connection. Not having my luggage go missing and not get delivered within 24 hours."

Cons: "You could have had my luggage arrive. Now I don’t know where it is"

Cons: "Delayed flight."

Pros: "3 - 2 seat arrangement and lots of leg room. Excellent boarding."
Cons: "Bread of sandwich was dry."

Pros: "It was a lovely easy flight, always lovely flying star alliance."
Cons: "Such a quick flight, everything was appropriate for that. Unsure exactly what would make it better"

Pros: "Everything"
Cons: "Nothing"

Pros: "The crew was polite and helpful. The wine was free and each seat had it's own screen with a good assortment of movies and TV shows."
Cons: "The food could be much better. Although coming from Sicily it's tough to compare."

Cons: "entertainment sound"

Cons: "45mn late"

Pros: "The food and service."

Cons: "I was asked to check my carry-on. I have used this carry-on more than 50x without an issue. I have even put it in the smaller compartments on smaller Bombardier jets. I don't have an issue with being asked to check luggage, but I resent being asked when others are allowed to take their carry-on onto to the plane without issue. Right in front of me while I was waiting for a baggage tag, others were being checked in with carry-on equal to mine and allowed to take it onto the plane. I can only surmise that my ticket limited me to one bag onto the plane, although they would not tell me this. This was not clear when I booked the ticket nor when I checked in on-line. I had a 40 minute connection in Zurich so was very concerned that my luggage would not make it. Luckily, it did make it to my next stop. Swiss Air seems to have different restrictions than other airlines which I have encountered before. I take ownership that I should be aware of a tickets restrictions but this was a multi-leg trip (5). However, I will tend to avoid Swiss air in the future, to avoid having to research their unique restrictions."

Pros: "Crew great service"
Cons: "Boarding was slow —delayed takeoff for nearly an hour"

Pros: "Entertainment"
Cons: "I would have liked a better selection of movies and TV series and games"

Cons: "It was delayed"

Pros: "We did not get on any flight to NY!!!!"

Pros: "Not applicable"
Cons: "See above."

Cons: "Nasty passport control person at gate check in"

Pros: "Les hôtesses ont été super gentilles. Merci!!!"
Cons: "L’espace entre les sièges est très réduit"

Pros: "3"
Cons: "Everything"

Pros: "Food was actually really good."
Cons: "Please let families with small children board early. This is the first flight I remember where I and other families with small children had to board with everyone else, and it's stressful for all involved."

Pros: "Check in easy"
Cons: "Weren’t told enough about delays ... very tight seating crew was friendly"

Cons: "30 mins late both ways"

Pros: "The crew was very efficient and very helpful. They were constantly attending to passenger’s needs."
Cons: "The landing was a little rough, but my friend said that it was windy here in NY. Otherwise excellent all around."

Pros: "Very good service"

Pros: "on time and got us there on time."
Cons: "untrained staff waking people up no flexibility with ordering GF dinner late"

Pros: "Excellent organization, food and entertainment. Impeccable service."

Pros: "People friendly"
Cons: "Food was poor, really poor, no options for the children Headphone socket in the seat"

Cons: "Bathroom not clean"

Pros: "Plane was comfortable (for a plane) and the staff were polite and efficient. The flight made up lots of time and the in flight snacks were very welcome."
Cons: "The flight was very delayed, and the communications from Swiss was lacking. In fact their app thought the flight had taken off and landed on time?!"

Cons: "Headphones are real cheap and hurt the ears...plus it has two pin socket where you can't use your regular headphones...please change this!"

Cons: "1h45 departure delayed with no compensation."

Cons: "Paucity of games that might appeal to non children."

Pros: "Over all I enjoyed flying with Swiss over the past 40 years. This was a first time my experience was not to my expectation."

Cons: "entertainment machine in my seat did not worked"

Pros: "It was an uneventful trip, which is what you want in a trip by air. Boarding was easy, seats are pretty comfortable, staff friendly and helpful."

Pros: "Staff was gracious and accommodating for whatever we needed. It felt much better than typical economy class. It made the 8 hour plus flight quite manageable."

Pros: "The crew members were polite and efficient."
Cons: "There was no climate control. Our rows were freezing cold. People were wearing coats and blankets. Four or five rows up it was warm. My husband asked for more heat and the stewardess said she would turn it up, but nothing happened. Cold air blew out of the ceiling vents for the entire flight. When we reached our gate, we then waited in a long line to have our passports and boarding passes checked again. There were several Swissair crew members, but only one person to check all of the paperwork for economy. Then another long line to show our boarding passes again, while the business class entrance remained unused. Swissair needs someone to manage this better."

Cons: "Time"

Cons: "Flight was 2 hours late. This is my second experience in a week with Swiss flights being 2-4 hours behind."

Pros: "What I liked is that they didn't really focus on the weight I had little more weight and they didn't really make an issue for me"
Cons: "Geneva airport is so busy on the weekend I had to stay in the line for 20 minutes it's a little annoying"

Cons: "smooth & efficient friendly crew"

Cons: "They checked at the gate all our hand luggages to make sure we didnt exceed the 8 kilo mark. This is very cheap and only suitable for the low cost airlines. I expect swiss air as a higher class flight to turn a blind eye on this matter"

Pros: "the entertainment system was perfect, there were lots of movies and shows to entertain you, including newly release films. there were games and music also availble. the seating was comfortable we had blankets and pillows. The beverage service great and the food was good to. although there could have been better options in terms of the dessert ( ice cream taht was provided)"
Cons: "the boarding was poor, we waited in line to board and they did not announce to us that we need to have our ticket stamped before we got to the door, as a result we were sent out of line once the ticket was stamped we had to rejoin the line from the back. When i got through they then said something was wrong with my ticket in which they took it and I was pulled out of the line. they should try to the ticket check and the boarding line at the same time"

Pros: "Nothing"
Cons: "Video screens didn't work. Seats were terrible and some broken. Flight crew was useless."

Pros: "Nothing distinguishes itself for better or worse than usual in coach."

Pros: "Very clean"

Pros: "Excellent boating procedure Friendly crew good service"
Cons: "Seats smaller, especially well the seat be afore head rest is pushed back!"

Pros: "The seats have been much better"
Cons: "The entertainment system is a little old (plugs are not universal), you had to use their (cheap) headsets."

Pros: "The crew was friendly, the food delicious, and the plane itself in highest quality and state-of-the-art."

Pros: "Amazing !"
Cons: "Nothing all good really"

Cons: "Very cramped aisle seat and I kept being knocked by passing crewe including knocking over a cup of water."

Pros: "Crew was generally nice and caring."
Cons: "Of course coach seat was not super comfortable. And speaker and screen at my seat did not work."

Pros: "Crew was nice"
Cons: "Screens have poor color quality Seat too small Legroom cut into by electronics box Row 45 next to bathroom and no windows"

Pros: "Premium economy was perfect, smaller cabin with less people, great flight."

Pros: "The flight was so delayed I missed my connecting flight to jfk."
Cons: "The flight was so delayed I missed my connecting flight to jfk."

Pros: "Meals were excellent and plane was very clean. Economy delight is definitely an upgrade worth considering with extra leg room and space in front of you in general."
Cons: "Boarding can get crowded so don't be in a rush"

Cons: "My bag was damaged in transit"

Pros: "Provides the service you'd expect from an international carrier. Boarded on time, seat actually reclines, meals, baggage, seat assignments are included in the price. Staff treat you well and the price isn't bad."
Cons: "Virgin website is slow and not intuitive. Couldn't get seat assignment until i was at the gate. No explanation why. Boarding announcements delivered via ESP. Half of the passengers were still in the boarding area because no one heard announcements. Arrived 30 min early but had to wait on the tarmac for 45 min for a parking gate. Baggage delivery at JFK took forever."

Pros: "Service, pilot updates, and seating were all great!"

Pros: "The flight crew was phenomenal, especially Daniella. Somehow we wound up with seats right next to the bathroom door, which would have been a pretty uncomfortable situation for a variety of reasons, but the flight wasn't full, and she helped us find a suitable place to sit. Also, my wife and I usually take our tea with honey vs. milk and sugar. Even though honey is usually one of the options for tea, she found a way to accommodate our request. The lunch meals were the best I can remember in a long time on an airline flight. They might have been the best I've ever had. The chicken curry was authentic, flavorful and spicy. Frankly my outbound flight had problems. My luggage got damaged. The transfer experience in Manchester left a LOT to be desired. I wasn't planning to use Virgin Atlantic again, but this flight crew (Daniella especially) redeemed Virgin Atlantic. They were attentive, pleasant, diligent."
Cons: "Only thing I didn't like about this flight was the boarding area. Once you get into that the area, you don't really have access to appetizing food (only vending machines) or even restrooms. That's one thing that could be improved."

Pros: "Friendly staff, so much food/snacks were offered. Good movies available."
Cons: "Nothing"

Cons: "Queue at boarding gate for upper class ticket holders Bus transfer to plane - Virgin is not a LoCo airline! Upper Class Service was slow - understaffed?"

Pros: "Service, meals, friendly and attentive FAs"

Pros: "The crew were friendly."
Cons: "The food was okay. There were more tasty options traveling to Heathrow versus from Heathrow to the NYC. The boarding process was a mess. We had to wait in an enormous line and then take a bus to the flight."

Pros: "The cabin crew were excellent!"
Cons: "I paid extra for Economy Delight seats for me and my wife. Shortly after take-off, our calm and comfortable more or less empty section of the aircraft was colonised by an extended family of Orthodox Jews in a kind of airborne West Bank situation. They weren’t in our section of the cabin at all to start with, and I don’t know why they were apparently able to get a free upgrade that I had to pay £100 for. We went from being in an almost empty cabin to being basically sat in the middle of an Orthodox Jewish kindergarten. It was awful! They were noisy, messy, were constantly getting in and out of their seats, the back of my seat kept getting kicked, and there was even a baby crawling around the aisle. We were surrounded. I have no idea whether this is characteristic of Orthodox Jewish family life, or just a completely inconsiderate family. They didn’t exactly ruin my flight, but they didn’t make it enjoyable either. I asked to be moved. The cabin crew were great and acknowledged the difficulty of the situation. My wife lost her window seat but at least we still had the legroom and peace and quiet."

Pros: "Legroom, lovely staff and all round good flight"

Pros: "Crew very friendly"
Cons: "Seats and legroom poor if you’re six feet tall"

Cons: "Older media entertainment screen with hard to use touch interface."

Pros: "Nothing"
Cons: "I had to run for almost 2 miles every time I had to change the flight. On the way to India they lost my one bag, and on the way back to US they lost my both begs."

Pros: "Quite a big choice of movies and TV shows to watch, more than enough for an eight hour flight. Normal headphone plugs so you can use your own."
Cons: "I booked together with my wife, yet we were allocated seats apart and were not able to be reassigned together. The leg room was so tight that I could not pick up things off the floor without putting my head in the next persons lap. Though the cabin crew were smiley and friendly, it was hard to get their attention when needed. The PA system is much louder than the entertainment, so announcements were ear bursting. The dinner selections ran out early, so a good proportion did not get their choice."

Cons: "We were told over the phone that we could bring our kayaks with us to Africa but the airport staff denied not only our kayaks, but also our paddles which were in a standard ski bag. Their excuse was that both the kayaks and paddle bags were 2 inches too long. .. TWO INCHES!!!!!! We had record of the person we talked to and the time and date, but none of that seemed to matter. It caused A HUGE INCONVENIENCE for us since we are in Zambia for 6 weeks without our gear to paddle one of the most challenging rivers in the world... the Zambezi. Now we are constantly trying to acquire the proper equipment with very little success. We run a nonprofit called the Montana Kayak Academy which provides free whitewater instruction to youth between 8 &18 yrs old and we will be sure to tell everyone we know to NOT TRAVEL WITH EITHER VIRGIN ATLANTIC OR BRITISH AIRWAYS.... EVER!!! VERY DISAPPOINTED! !!!!!!!!!!!!!!!!!"

Pros: "NA"

Pros: "Everything went very fast and smooth. I didn't have to queue for the boarding. The Sita were very comfortable, the crew very friendly and halepful and the selection of the movies A+."

Pros: "Choice of movies was good, but told the flight over was better. I flew another airline. Had no issue checking one bag in for free, but I think that is standard on an international flight."
Cons: "Entertainment systems take up foot/bag space underneath the seats. Was not able to get more than one glass of wine, even though I missed the first beverage service, that is my fault though, but I don't recall it being an issue getting a drink between services. Entertainment systems had contrast issues and it seemed like a lot of people 8 - 10 had issues since they were using iPads instead of the built in monitors. A lot of wear showing on the entertainment systems remotes."

Pros: "Efficient service"
Cons: "Entertainment screens were of poor quality"

Cons: "My headphones and those of my neighbors did not work."

Pros: "The staff was so helpful and upbeat and somehow they stayed that way the whole 8 hour flight. This was economy btw! More good things: Comfy seat, personal entertainment screen, really nice food. One free checked bag, bathroom was bigger, (it may have been a handicapped bathroom)."
Cons: "Nothing was a problem at all. (I saved "excellent" for the things I really wanted to emphasize)"

Pros: "Food was great, plenty of it also"
Cons: "I'm 6'4" and there was no acknowledgement by the crew that I was squashed into a tight seat."

Pros: "Staff was friendly and welcoming."
Cons: "There was nothing not to like."

Pros: "Easy check in and boarding."
Cons: "Uncomfortable seats and poor food."

Pros: "Virgin Atlantic had a very attractive decor.Food was great& staff as well. Polite and professional ."
Cons: "The seat I had was a bit snug leg wise and recline wise. Could not get comfortable at all."

Cons: "cabin was nice but cold"

Pros: "I liked the entertainment system, free adult beverages and boarding process"
Cons: "I don't like that they have you pay extra for picking seats that have no extras. No preboarding. No extra legroom."

Pros: "Service, food, etched all fine"
Cons: "Fees to assign seats in advance are very high. Sat on the Tarmac a while before takeoff and after landing."

Pros: "Food and beverage choices excellent"

Cons: "Cold draft at all times."

Pros: "Flight was on time .. Friendly crew. Good entertainment system"
Cons: "Seats uncomfortable and leg room very tight . Didn't sleep well."

Pros: "Everything except the seating - far too cramped now"
Cons: "Seating! Seats getting ridiculously tight"

Pros: "The crew was very good with the passengers and attentive"
Cons: "The leg space is very tight, it was very hard to sit specially for longer flights it's not that comfortable"

Pros: "free wine, good food, and friendly cabin crew? what more could you want? oh, a good variety of entertainment. I watched two documentaries and "The Lobster" a great choice, never would have seen it otherwise."
Cons: "The seat cushions are really hard and not very comfortable to sit on for a long flight. If you could get a higher density foam that would be great. my bum was a bit sore/uncomfortable."

Cons: "45 minute delay on runway after landing was very very frustrating."

Pros: "Staff were friendly and flight was clean. Lots of movies to watch."
Cons: "The seats gets smaller each year. For a seven hour flight, the seats are very uncomfortable, no space to move. The flight with the hand held remote control TV had poor visual quality. It was hard to watch movies with dark background."

Cons: "It was late leaving."

Pros: "Good was decent."
Cons: "This VS25 flight, whatever airplane it was felt old and the v poorly designed "seat back pocket" sat so low and protruded out so much that it pushed against your knees. V uncomfortable."

Pros: "Nothing"
Cons: "The food I had food poisoning"

Pros: "Extremely uncomfortable seats in the Economy section and a very confusing remote control to maneuver the entertainment screen. The crew was excellent so it's not their fault. The food was passable but those white bread rolls got to go. My luggage didn't arrive so let's hope they bring it today."

Pros: "Flight D001 (Delta / Virgin, LHR to JFK) Staff were terrific. The food was the best I've had so far (and I fly a lot!) The choice of entertainment was varied and excellent. Flight was smooth and captain was very communicative."
Cons: "Chair kept snapping back to position from recline (33E). Man behind me kept banging on the screen behind my head Inspite of announcement not to do do from cabin crew. If they could catch ppl doing that and say something that would be great :-) (although I realize if course the this isn't their fault.)"

Pros: "Good service, comfortable seats and quick flight, great combination for a long trip."

Pros: "The flight attendants were stellar--polite, respectful, helpful, attentive. I want to particularly commend the attendant who, after I notified her that someone was very ill in the adjacent bathroom, stood discreetly nearby and offered the person a glass of water when he emerged. Very considerate."
Cons: "The transfer was a horrible, stressful experience. We knew it as a short connection but Lufthansa had accepted it. On our outward bound flight three weeks earlier, we were all met and escorted swiftly by a flight attendant from the first leg plane (EWR-MUN) to the second leg plane (MUN-Nice) to ensure that we all made it onboard. Impressive. On our return journey, no such luck! No attendant to meet us, and a huge line at immigration, full of panicked and stressed-out passengers jockeying for position, with no-one from ANY airline there to do a triage for those with the shortest connections. Ridiculous. In addition, the passport-scanning machines were very slow and quirky. My own passport was rejected because there was no evidence I had passed through Munich on my outward bound journey!! RIDICULOUS. I managed to slip through to a human being and begged the immigration officer to let me go through with my husband, who had had no such problem. The officer told me he could not find a stamp from my earlier transit through!!! Eventually I suppose he did because he let me through. The stamp was there, I found it, but it had been sloppily applied and was half off the page...hence the rejection by the scanner. We made the flight by minutes. NOT GOOD! Surely Lufthansa could do better in their own country???"

Cons: "Slim seats very uncomfortable and legroom too little"

Pros: "The food and drinks was very good."
Cons: "The flight was late."

Pros: "Easy check-in and helpful staff. I would absolutely fly with Lufthansa again"

Cons: "The plane lands a considerable distance from the airport, you walk across the tarmac in the rain to a bus, and then the bus ride is almost 15 minutes. I expect Lufthansa to have a better berth at Frankfurt."

Pros: "Nothing"
Cons: "Nothing"

Pros: "Free refreshments. Funny cabin crew!"
Cons: "There was very confusing and contradictory information on what you can take with you on top of your cabin luggage. e.g. Can you or can you not take a small shoulder bag with you."

Pros: "Nie odbyl size powodu opuznienia samolotu z Chicago do Londynu"

Pros: "Comfortable, timely and pleasant overall."
Cons: "N/A"

Pros: "Flights were cancelled that day due to a storm, but Lufthansa were able to fly an empty aircraft from Rome to fly us from London to Frankfurt. Despite the circumstances, Lufthansa were able to still offer catering. Thank you for your cimmitment."
Cons: "Lufthansa in general could invest a little more in the food they serve. Lufthansa's domestic and inter European flights are never a culinary highlight. :-("

Pros: "more than 2 hours spent in the plane which was the reason for waiting at the airport taxi and extra pay."

Pros: "Everything was good."
Cons: "everthing was good!"

Pros: "see above"
Cons: "see above"

Pros: "everything from the boarding and check-in process to in flight comfort."

Cons: "Most cramped seat I've ever sat in. Couldn't even sit because my knees hit the seat in front, before my but was in the chair."

Pros: "Priority boarding with small kids"
Cons: "In London I was required to ask fro this priority boarding with kids if not asked I would be queuing with small kids for 15 minutes.. (whilst In Frankfurt we have been invited to be boarded as first ones without asking for it.)"

Pros: "Coffee was excellent"

Pros: "terrible earphone, could listen only on one ear."

Pros: "vunderbar"

Pros: "very clean and nice cabin space"

Pros: "I loved how friendly the airline attendants were."
Cons: "I didn't like how in the Munich airport I couldn't find a place to plug my phone in. they should make those more accessible"

Pros: "Staff/stewards were very upbeat and pleasant, professional and were perfect at looking after very tired customers (at least for me)."

Pros: "Staff attentive. Came by very frequently."

Pros: "That my bag was at Johannesburg. My first flight was delayed due to a technical issue which meant I only had less than an hour until my connecting flight. It took me almost 20 minutes to walk to the gate just in time for boarding and was pleased that my bag had made it onto the same flight. There was loads of leg room in economy which as a tall person is really important."

Pros: "more comedies movies and more up to date soccer"

Pros: "I'v said it all above. Liked everthng"
Cons: "nothing"

Pros: "The flight attendants were good - they run a tight ship, both from a safety perspective and looking out for the passengers. That said, they should have allowed me to move to any open seat, except first class, to accommodate any passenger with broken equipment at the seat they selected."
Cons: "This old plane had broken seats with broken entertainment equipment. After changing seats twice, my ultimate seat still had a loud buzz in the sound system. The flight attendants should be allowed to seat an inconvenienced passenger in any open seat in the event of broken equipment. Space in the seats was ridiculously tight for a 7 hr international flight."

Cons: "Lufthansa is not handing out any bottles. Water is served in small plastic glasses and does not come by often enough. I got off the plane dehydrated."

Pros: "Traveled with my dog. They had empty row so United moved us there so dog can be comfortable under the middle seat. Staff was very nice and offered water and ice for the dog."

Cons: "Pilot did not yet to avoid turbulences, which were pretty bad. They also lost my luggage which arrived after three days."

Pros: "Comfortable and convenient"

Cons: "It was too warm. The air above was not cool"

Cons: "Boarding was very slow, crew told us there was nothing they could do to speed it up, it plane was late, unfortunately when we arrived in JFk we had to wait about 1 houre to get to the gate."

Pros: "leg room! excellent entertainment options"
Cons: "long lines. delays waiting in hot jetbridge"

Pros: "Crew was good."
Cons: "Didn’t get the seats we paid for. We should have been in row 3 but ended up in row 30."

Pros: "Yes"

Cons: "No AC and awful smell"

Pros: "We arrived only about an hour late?"
Cons: "We boarded late which seems to be the norm for Iceland air. Usually when an airline is a few minutes late departing they try and explain why and then make up the time, but we received no explanation for the late boarding, or the even later departure, or for why we lost even more time in the air."

Pros: "The attendants are all nice and efficient!"

Pros: "Not a lot."
Cons: "Boarding via bus just takes forever, get a legitimate jet bridge. Also the airport has about 20 seats at each gate for 80+ passenger planes, leaving a lot of people sitting on the floor."

Cons: "See above"

Cons: "The seat bottom cushion was extremely uncomfortable."

Pros: "Ok price"
Cons: "No checked bags included, but this was unclear at the time of purchase, even though it was an international flight."

Cons: "Boarding at KEF needs to be more organized."

Pros: "Pillows and blankets free of charge."
Cons: "You had to go through their customs to change plans. Then you had to board a bus to get carried over to your connecting plane. There was not enough time allowed between flights to do that. They did not have enough bathrooms for all the flights coming in at the Iceland airport. Iceland Air is basically a travel agency in an airplane for Iceland. A lot of pushing by the company to stop in Iceland for a few days and buy Iceland products. It was a lot of hassle to cross the Atlantic on Iceland Air, and I will try not to use them again."

Pros: "Got home safely"
Cons: "No meal was provided. Captain's announcement was barely heard - poor PA system or he or she did not speak clearly"

Pros: "Loved the personalized tv in front of me and plenty of space above me in the middle seats!"
Cons: "There were no snacks"

Pros: "The beet salad and the bouillabaisse were both excellent. The flight attendants were attentive and helpful. Wide selection of entertainment choices."
Cons: "Our connection from Zurich arrived as boarding had begun in Reykjavik. When we arrived at the gate, it looked like business class had already been called, so there was HUGE mob gathered about the gate including small children. An employee worked her way through the crowd randomly checking passports and marking boarding passes. Eventually we made it onto the shuttle which drove us out to the plane. I wouldn't like to fly Icelandair overnight because I wouldn't be able to sleep at all in the business class seats since they don't recline that much."

Pros: "Spacious and great service. I will fly Icelandic again."

Pros: "Inexpensive tickets"
Cons: "No inflight meals"

Pros: "Poor communication. Old planes. Late departures and arrivals. And the staff has zero f@;$s to give."
Cons: "See above."

Pros: "The lights in the cabin were great set up to look like the Aurora"
Cons: "Offered 1 drink and no snack. Rarely do you see the crew on their flights"

Cons: "Again, there was no jet bridge to board the plane in Reykjavik. When we arrived in New York, it took 1.5 hours for our bags to arrive on the baggage carousel. That is an absurd amount of time to wait for your bags, especially when the crew's bags were unloaded from the plane within 30 minutes of landing."

Pros: "The inflight entertainment was really nice and enjoyed the Iceland layover information. Crew were professional and attentive."
Cons: "Felt like a budget airline, so don't expect any free snacks or the ability to carry on large backpacks that you normally could on other airlines."

Pros: "Better movies assortment and also TV Cooking newtwork"

Pros: "Entertainment was broken the entire flight; unable to charge electronics; food available for sale was really limited. All in all, not a great flight."
Cons: "No acknowledgement from the crew or apology about broken entertainment system."

Cons: "Reykjavik Airport was the worst for lines, delays, and boarding, You are bused to and from the terminal/plane."

Pros: "Free movies and interesting Iceland travel videos, glacier water, peaceful music."
Cons: "I didn't like one mass line for all economy tickets when it came to boarding- I prefer airlines that call people to board by group. Less hectic."

Cons: "Extensive delays"

Pros: "They left on time and arrived on time."
Cons: "Maybe, if not a meal, some snacks."

Cons: "Airport in Iceland severely overtaxed. Too many panes and people, not enough infrastructure"

Pros: "The service was superior. They made sure my younger daughter were occupied and gave a small gift and snack. The movies were great way to pass the time, overall experience were great! We would be a return customer for sure!"
Cons: "Nothing really, we are very pleased!"

Pros: "Staff was very nice and I loved that I actually didn't' have to pay for luggage. I was also offered a free drink."

Pros: "The entertainment was really terrific, selection was good and the equipment was brand new."
Cons: "I felt like it was bumpier than other flights I've been on. I know that's highly subjective and a product of weather but it felt like it was excessive. There wasn't a lot of communication about conditions from the flight crew like I've had on other flights. It took forever to board."

Pros: "I liked that they provided bottled water when boarding. The seats were comfy and had sufficient leg room. The crew was friendly."
Cons: "I think that for a flight of this length, a complimentary meal should have been provided. I had to purchase a meal. While it was satisfactory, I felt that $15.00 was excessive."

Pros: "See previous review.. Best of the best."

Pros: "I loved the informative videos about Iceland! I had planned to watch them all, but my video screen stopped working for awhile. I thought about switching seats, but I ended up sharing headphones with my boyfriend and watching some movies instead."

Cons: "Baggage claim took over 1 hour."

Pros: "Excellnt service, fast boarding, great communication"
Cons: "Took a while to take off,"

Cons: "I paid a lit of money for the flight from JFK and there was no food on the plane."

Cons: "The attendant taking our tickets to board was very obnoxious. I complained to the crew chief who agreed her behavior was unprofessional."

Cons: "The seats in premium economy were extremely uncomfortable and because of this I doubt I will be flying Icelandair ever again."

Pros: "I was worried due to the negative reviews about the airline , but the flight was on time, the cabin comfortable, the crew friendly, and the ride was smooth."
Cons: "I didn't like that they didn't serve a meal or man the flight, but that's what you get when flying a low cost carrier. No frills."

Pros: "Seats are comfortable."

Cons: "Boarding was unorganized."

Cons: "Seat 8G does not have a window."

Cons: "When we arrived at Keflavik airport the terminal was immensely crowded with several flights due to leave the US at once. It was overcrowded to the point of being uncomfortable and there was a 30min+ wait to buy food from the only shop. As a result we did not have time to grab a bite to eat between flights. My partner was subjected to additional TSA checks which I am aware is a random check and a nescessity but due to the amount of flights departing for the US this took an extra hour, and delayed our flight. I'm thankful that Iceland Air didn't leave without us but it was an immensely stressful experience that I don't wish to go through again."

Pros: "Generally well run and a pleasant experience."

Pros: "Seat was comfortable"
Cons: "In addition to the above when i finally got to JFK my luggage was still lost"

Cons: "Delay on boarding"

Pros: "Entertainment very good - lots of good movies that I had not seen. I love that there was not an extra charge. The service on the flight was good."
Cons: "The boarding process in Reykjavik was just awful. First we had no warning that Gate D would require such an extensive wait, so we spent too long in terminal eating and then panicked that we might miss our flight. Next there was a problem boarding our plane. There weren't enough buses, so we spent over an hour standing in a cramped line that snaked down the hall in an extremely crowded airport with people trying to squeeze though us. It was really uncomfortable. The worst was the crew waited to process people and send them in to the waiting area until a bus arrived, so this added to the wait time. I think tourism is popular in Iceland now and you all need to figure out how to make your systems better. I loved Iceland but I wold seriously need to think hard before booking another flight with you."

Cons: "Hi, Pliz sort out the menu,the food was rubbish."

Pros: "It was great."

Cons: "Great experience"

Pros: "No"

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."
