Airline reviews

Cons: "JAL cabin attendants and people from customer center were very professional and nice"

Cons: "More variety of movies"

Pros: "The coach seats were larger than those on domestic flights. The window glass was dimmable for ideal lighting."
Cons: "The arm rests did not go up all the way. This made it difficult to maximize comfort with my wife."

Cons: "Better food"

Pros: "33" seats"
Cons: "nothing"

Pros: "The seat was very spacious"
Cons: "More space to put things"

Pros: "The meals were an experience in itself. It felt like I was at a 5 star restaurant."
Cons: "The seat cushions in economy class could be softer. My rear end was feeling it after the long 11 hour flight from Chicago to Tokyo."

Pros: "The EMIRATES flight was nice. Japan airlines has good leg room."

Pros: "Perfect service, never had a more pleasant and attentive crew"
Cons: "Movies were pretty much still the same as 10 weeks ago. Not possible to sleep in the seat in premium economy right by the toilets and galley. Constant door clattering and toilet flushing. In other cabins the noise wasn't as bad, probably better insulated?"

Pros: "The flight crew"
Cons: "More space"

Cons: "The food and drinks were sub-par"

Pros: "From the food (dinner and lunch), to the spacious seats, to the impressive beverage selection, there is little I would change. The small touches, including coming through the cabin regularly with delicious green tea, made this a wonderful flight."

Pros: "Service was excellent. Premium economy seats well worth the few extra $$."

Pros: "They were very accommodating and helped ensure a good travel experience (first time traveling with a young child)."

Pros: "Staff are the best of all airlines I have been in."

Cons: "Over all"

Pros: "While many other airlines are cutting down on their service quality and amount of food on their flights, Japan Airlines has done the reverse: offer excellent food and great service at every tier, including economy. We took a flight from NY to Tokyo and felt like it was one of the best long haul flights we have taken."

Pros: "Service and Entertainment were great. Lots of legroom is great."
Cons: "There are no air vents per seat so on the whole I was very hot and uncomfortable during the flight. One other detail: this is not Japan Airlines fault, but at LAX we had to sit on the runway for an hour because there was some confusion about the parking space for the plane. After a nine hour flight, to sit and wait for another hour was very uncool."

Pros: "Everything was excellent no complaints"

Pros: "Customer service was on point . Thanks Again !"

Pros: "Clean plane, very nice crew."
Cons: "Flying coach is always cramped for a tall person!"

Pros: "Service and airplane are the best!"

Cons: "I know this isn’t really the fault of the airline, but there was a loud toddler sitting behind me. It was frustrating, because the mother did not seem to do anything to have her child be quiet. It makes it hard for everyone around them to have comfortable rest, especially as this was an overnight flight. I have flown over the years with up to 5 children and do know how hard it can be, but it is important to foresee the needs of the child. I wonder of the attendants could have been a little more firm with the mother to ask her not to let the child roam the aisle."

Pros: "I got an upgrade!"

Pros: "Crew was very pleasant"
Cons: "Food was fair, not great."

Pros: "The flight was smooth and the seating was comfortable."
Cons: "It was an evening flight, but the cabin lights were never dimmed, so it was difficult to rest."

Pros: "I was highly impressed with Japan Air's staff both at the gate and on the flight. It was incredible customer service. I get really anxious with flying and traveling in general and was so eased just by their friendliness and organization. Thank you! I also forgot to write a review but my flight from San Diego to Tokyo on June 27 was also amazing. I was really stressed out over some logistics of my trip and the people at the gate in San Diego were so helpful!"

Pros: "The flight attendants were very kind and attentive."
Cons: "A bit hard to get in and out of my seat 8A. But the seat and bed itself were comfortable."

Pros: "Went premium economy for such a long flight- NYC to Tokyo- to Sydney. Seats were great as was crew and everything!"
Cons: "No complaints!"

Pros: "Good service and selection of movies.Boarding is orderly. Crew very courteous. . We have been flying JAL for a few times and never regret"
Cons: "Boeing 777 is not as attractive as the new 787.e.g. Ambient lighting, cabin noise control etc., are far more superior in the 787"

Cons: "Requested Vegetarian Meals. Didn't get them"

Pros: "Plenty of leg room, which as a tall person I truly appreciate. They give you slippers, blanket, pillow on every (international?) flight. I flew Korea to Japan and Japan to Hawaii. Got free meals on all flights, even my short two hr flight between Korea and Japan. Free booze too!"
Cons: "Small overhead bin. Not deep enough, I had to turn my suitcase sideways. Luckily there was no one in our middle seat or I'm not sure where they would've put their baggage."

Pros: "Economy seats were extremely comfortable and roomy. What a difference that makes."
Cons: "Movies available tended to be either action/terror/suspense, or old movies. Very few real dramas."

Pros: "The crew were the nicest group of flight attendants I have ever encountered. The offered assortment of snack during my flight. I got a scented warm hand towel before they service me a meal. They even use real silverware in economy"
Cons: "The only thing I didn't like was the temperature of the plane. It was quite hot (felt like 75 degrees inside)"

Pros: "Very clean. They check the bathroom pretty often un-like AA. Good food."
Cons: "I always prefer this airlines."

Pros: "As always, the Japan Airline's stewardess takes care of you so well, they really make your trip a very comfortable one. (Think the Japanese airline crews are the most caring, with thorough service, and they are surely one of them."

Pros: "Good food, real silverware, blanket and pillow provided to economy class, crew offering water and tea through the cabin constantly but unobtrusively."

Pros: "The whole service was great. And the airplane arriving on time."

Pros: "The service, food, entertainment, everything was perfect. Thanks so much"

Pros: "Customer service was awesome and the food was good"

Pros: "My son and I enjoyed the courteous and genuinely friendly service and attention from all flight personnel paid too us to ensure a wonderful experience to and from Japan. From Hawaii JAL manager upon check in concern for my son not feeling well to the attendant realizing we spoke no Japanese to apologize and begin conversing in English, every one was pleasant and professional in desire to please us and make our trip so comfortable."

Pros: "evening flight. not too crowded"
Cons: "delayed by 1 hour meal was so-so"

Pros: "Almost everything"
Cons: "Can't say because I was satisfied w/ my flight"

Cons: "We couldn't land in Narita due to bad weather, so we did emergency landing to Haneda to refuel and go back to Narita. But after we got off in Narita, the immigration is chaos. Nobody arranging it and people just going wild, nobody knows where the line should begin. We spent 2 hours plus in the imigration line. So from the scheduled time to arrive at Tokyo 5pm, we get to our Hotel at 2am. Good job Narita airport!"

Pros: "Very nice flight attendants. Good meals"

Pros: "There was a huge check-in line but it went quickly because they had 8-10 ticket agents with luggage 'helpers' for the agents. Of course there was a problem with my reservation that they had never seen before which manifested itself by them not being able to print my boarding pass. They called Tokyo and were told that they had never seen my problem before either. Anyway, the ticketing supervisor stayed with me for 45 minutes until they could over come the problem. I would be a rich man if I had a nickel for every 'So-sorry' I got that day."

Pros: "full service"
Cons: "long flight"

Pros: "I booked a flight with JAL; my flight to Japan shafted me with American only. But, this flight was premo! The plane was bigger, more room. The entertainment was much much better than the American Airlines archive. The seats and accessories like pillow, blanket, etc. again much better. 12hr flight was over in what felt like about 5hrs (I watched Star Wars and Hunger Games)."
Cons: "The fact I'm too poor to get a premium or above seat."

Pros: "Yes, it was great."

Pros: "Space and courteousness"

Pros: "Cheapflights ..I will book my ticket from you again.. I am so delighted."
Cons: "None"

Cons: "Wonderful food and service"

Cons: "Food was really unpleasant and entertainment all out of date movies"

Pros: "The food and the crew were great."
Cons: "I am yet to find an airline that has any semblance of comfort in economy class for someone 6’ 2”, and that isn’t even tall! It would seem that the seats should be tall enough not to have the headrest push on my shoulders.....such as making it adjustable enough to be used as a headrest."

Pros: "Plenty of legroom in economy."
Cons: "Vegan food option unimaginative. Tomatoes used in every dish!"

Pros: "ANA is always on time and the crew is always attentive."

Cons: "N/A"

Pros: "I missed my flight. The customer service agent was awesome!"
Cons: "Flying United. I missed my flight. The gate was packed with people so I sat literally a quarter mile away. The flight was delayed and I got a text telling me new departure time. I show up for new departure time. Plane left six minutes earlier. First thanks for the bad information. Second thanks for not paging me. Third I don't care when the plane is supposed to leave. Just tell me what time to be at the gate so I can stand around after an international flight. Oh and if a flight attendee to squawk rudely at a paying customer when we do land, why I'd just have to ask myself AGAIN ... why do I fly United?"

Pros: "My 96-yr-old father was given an airport wheelchair after we checked his own transport chair. He was wheeled through security and to the departure gate. We were advised they changed us to a bulkhead row w/an unoccupied seat adjacent to his. Twice during the flight one of the flight attendants came to tell him that she would help him off the plane so to wait for her after the rest of the passengers disembarked. The meal was very tasty.Chicken karaage was not crispy but I wouldn't expect it to be. The rest of the items were well seasoned with the right consistency. Dessert was a flan custard with passion fruit sauce (very Hawaii!), even including a few seeds from the fruit as garnish."

Pros: "It was an awesome flight, very nice and great service,"

Pros: "Didn't realize I'm flying united airlines. Nowhere on my itinerary was it mentioned. The whole time I thought I'm with ANA all the way"
Cons: "The flight itself was good but booking with bayaan, never again. I have used kayak many times but for the first time since I booked vayama changed me flight 6 times. They also could have mentioned my first 2 legs of my flight was with united. I tried to check in online thru ANA, couldn't go thru with many attempts until finally I called and the agent mentioned to check in thru united."

Pros: "Clean cabin. Courteous and friendly attendants. Inflight amenities were excellent. Meals were perfectly portioned and delicious!!!"
Cons: "N/A"

Pros: "The ANA crew is always exceptional. Drinks and food are constantly being provided and the crew routinely walks about the cabin to ensure passenger needs are being met."
Cons: "For some reason, other countries do not use a number system when boarding. This often means if you're not paying attention, you could be the last to board the aircraft because a line will form almost out of thin air. Minor issue, but a systematic boarding procedure would be good."

Pros: "Great movies!!"
Cons: "Terrible seats- difficult to find s confirtsble position."

Cons: "I waited 20 minutes for my baggage to return"

Pros: "In-flight service from staff was excellent as always, food is good but not outstanding (but let's be clear this was economy class), movie selection is good."
Cons: "From Japan to other places they're always organised, but boarding in London was a little chaotic which is a common problem for ANA flights in other countries *to* Japan - they hadn't set up signs properly or made clear announcements for families with children, First Class, Business class boarding etc. The First Class/Diamond status queue (not for me!) was actually set up in front of a supporting pillar, basic organisational things like that. On balance though, still a top-class airline."

Pros: "Cabin crew provided great service!"

Pros: "Crew was attentive."

Pros: "The crew was amazing. seats were comfortable. The seats will be super comfortable, if there are more leg space."

Pros: "Arrived on time."
Cons: "Was a B Grade effort by the crew. They were there to get their pay check & no more....very disappointing."

Pros: "Efficient"
Cons: "Better food, better selection movies"

Pros: "Better flight as bigger craft and no neighbours in my row so I got some sleep."

Cons: "Way too cold"

Pros: "Boarding was better handled in Singapore - but then that’s Singapore! All very smooth and French champagne served on the flight all the way home! The Kayak website is excellent and I wouldn’t hesitate to use it again - $1,000 cheaper for the flight from Moscow to Singapore than what I could get direct from Singapore Airlines! Well done Kayak!"

Pros: "Spacious and clean"
Cons: "Crew wasn’t attentive. Brought wrong order, forgot order, walked by hurriedly and hit passengers. Empty sauce on the Tray- when asked said it was for presentation!"

Pros: "It’s worth it to pay a bit more for the extra legroom seats."

Pros: "Not much"
Cons: "Not as good as they were once"

Cons: "Our flight to Bali was cancelled due to the volcano eruption. We did not receive any compensation, but Singapore/Silk Airlines told us they were able to get us a flight home to LAX instead, but that it wouldn't be until the next day. We spent money on a hotel and food and waited until the next morning, got to the airport early for check in only to find that Singapore/Silk had in fact, given up our seats that they had promised us. They said that we now would have to wait another day just to get a flight from Singapore to LAX. We asked to speak with a manager, and eventually were able to get two seats due to cancellations. This was intended to be a very special and romantic trip that was essentially ruined. Since no one could have anticipated that the volcano would cause cancellation, we should be refunded for our flights. We are so crushed that we did not get to go to Bali, and now we may NEVER get to go because we are out of money. At the VERY least, the leg of our flights from Singapore to Bali, and Bali to Singapore, should be refunded. We are extremely disappointed."

Cons: "Not enough quantity of each type of food. I did not get the cold noodle I want and end up eating sandwiches."

Pros: "With 15 and 1/2 hours on the flight ahead, I was dreading the long, tedium of sitting for hours upon hours. But Singapore Airlines made the time fly with friendly service right when you were getting hungry and pleasant assistance when requested. Thank you Singapore Airline Flight Attendants!!"

Pros: "Service was best in class"
Cons: "Planes are old. They never seem to use newer planes on the Brisbane leg."

Cons: "Old plane. Old in flight entertainment."

Pros: "Reasonable price"
Cons: "Missed flight for medical reasons with 9 month old son, attempted to use remaining onward flight to Europe and return through Swiss which was refused! Most unreasonable, cheating me of my payment. I have since sought legal advice and contacted travel agent regarding, seems case law from several instances in my support. I had to pay thousands for new flight Austrian Air. Swiss thieved my money and I dont mind saying so. Unfair and unfair conduct. I am saving this letter for twitter to tell my friends of my disgust.

Pros: "Entertainment, crew was very hard-working."
Cons: "Economy seats are way too tight, had severe problems with knee room when seat in front was reclined. A terrible passenger just forward of me had no regard to this issue and refused to be cooperative. Food was lukewarm at best and was on mildly appetizing in economy."

Cons: "Entertainment Oryx One, lunch quantity aswell. FPML had one tray, VJML and AVML had the same packed wrap."

Cons: "My baggage was lost!"

Pros: "Polite crew, food was pretty good."
Cons: "Did not have the duty free item I pre-ordered. I asked the crew 4 times about it, four times because they said that they would check but they never got back to me to tell me that it was out of stock; until I pressed the issue."

Cons: "Legroom"

Pros: "In my departure flight, there were many empty seats and the crew let us move to another seat to lay down and sleep. Also the food was very good and there was a great selection of movies."

Pros: "The overall experience"

Pros: "Awesome experience provided by inflight crew, who attended to all your needs for this long for flight. Made us feel really at home!"

Pros: "Friendly staff"
Cons: "The food was very poor"

Pros: "Every thing is good in Qatar airways"

Pros: "service, food and cleanness"

Cons: "The website is not easy to navigate."

Pros: "The plane from Johannesburg to Doha was Fine but not as wonderful and comfortable As flight from Doha to Chicago"

Pros: "Leg room was relatively better than the Doha to Atlanta leg."
Cons: "No goodie bags this time"

Pros: "Ground crew was helpful On Time Flight Clean aircraft Good food"
Cons: "seat was not much comfortable"

Pros: "Food was better than expected. Entertainment as good as any major airlines. Planes were new and modern."
Cons: "Flight attendants are not friendly and rude. Seat had a problem reclining."

Pros: "I like the service very much. Flight attendants are very friendly and helpful, polite. After the flight I got some present. Kit with socks eye mask and lip balm, which was very nice."
Cons: "Dnt have anything to say what I dnt like. Everything is great."

Pros: "I liked the organized boarding prosecution, everyone was seated by the boarding zone so there were no mess and no fight over who gets to go first in the plane. the food was good too, again vegetarian options and very good quality. I"

Cons: "Seats were not very comfortable for economy class for a journey as long as these ."

Pros: "Polite staff keen to help"

Pros: "Great on board bar"

Pros: "Their food and crew was good."
Cons: "Seats are very small now and the entainment system was all messed up that day for the whole plane. We were trying to watch something else and system was playing something else."

Pros: "The food was the best airline food out there. Also, the regular economy seats recline more than other airlines."
Cons: "The boarding process was chaotic. There was. O system to the boarding and it made for a lot of pushing to get in line."

Pros: "Boarding, the welcome on board, the food choice and quality were all excellent. The seat was comfortable and I got a few hours sleep. The entertainment screen was big and clear, and the choice of films was good."
Cons: "The choice of films and tv programmes, was good, but before watching each one i chose, I had to endure a couple off minutes of an advert- the same one every time."

Pros: "Everyone on duty!!"

Cons: "I was seated between two overweight/obese passengers and as such was very uncomfortable throughout the long-haul flight. There was very little room to move as their body habitus spilt over onto my seating area and occupied the arm space. There needs to be serious consideration to make it mandatory for overweight/obese passengers to purchase two seats to accommodate their size."

Cons: "I checked in a couple of hours after checkin open but unfortunately I could not get my preferred window seat, got a middle instead. But still the leg room would have been ok but the middle seat (second row behind the bilkhead row) had the front passenger's entertainment system arranged across the footwell, not sideways, so it completely blocked the footwell and prevented any stretching of the legs. I am a tall passenger and this caused much discomfort on the flight, I had to keep getting up to walk around. I also found the seat bottom quite uncomfortable (not enough padding I think), butnghis could have been made worse by the footwell issue. Regards Neil"

Cons: "I had 2 checked in luggage, and both TSA lock on it was cut. Since it was TSA lock, I do not understand why both locks were cut instead of being opened with the international key. it cost me 10 USD it for the locks."

Pros: "Quick and easy boarding and decent crew."
Cons: "Food wasn't great, but edible. No options for a vegan who didn't choose a vegan meal as the flight was booked last minute. Unhealthy food."

Pros: "The food you serve is good! We also appreciated the little gray packs of toothbrush, toothpaste, socks, etc. that you shared. The staff is very professional, and we enjoyed our flight,. We enjoyed the "quiet room" in the airport."
Cons: "I had a little trouble with the dvd monitor."

Pros: "When we flew into Melbourne it was not a happy experience. Seats were cramped and arm rests wouldn't raise. The flight out, even though on the same model plane, was better. There was more room and we could raise the arm rests. For a 13+ hour flight that makes a big difference."
Cons: "Because the tickets listed the same type of plane in both the bad and not so bad flight, it is very hard to know what we're going to get. I'd love to be able to plan to avoid the bad experience, but if they use the same plane in two configurations, there isn't enough information to do so."

Pros: "The food was amazing and so were the staff, would definitely fly Qatar again and recommend it to others!"
Cons: "The layover is very short, my first flight from LAX to Doha was 40 mins late so I barely made last call from Doha to Dubai and my bags didn't make it. I did however have my luggage delivered the next day to where I was staying in Al Ain for free so that was great!"

Cons: "The food could be better."

Pros: "Food came out 1 am melb time ,2 hours after departure ."

"Smooth trip with excellent service."

Pros: "The Boarding Emirates at Logan Airport is a nightmare. The staff are unhelpful, and take long time to process Transiting passengers. The Desk is understaffed, and the staff is rude."
Cons: "The flight has enough crew on board, but the staff usually stand together in the galley and keep gossiping, instead of going around once in a while and check on passengers. It's a long flight and crews change but the passengers don't."

Pros: "Everything was outstanding"
Cons: "Nothinng really"

Pros: "Great entertainment, great seating and space comfort. Overall a great experience. But, Etihad airways is still better than Emirates."
Cons: "Longer wait for boarding. The assigned zones were the last possible ones. Zone F or something similar. Flight attendants were okay, cared less for economy class. Also, Bluetooth headphones pairing did not work."

Cons: "Slow to board."

Pros: "Really liked the long journey. Was a bit nervous given the 15 hour flight but was pleasantly surprised. Service was good as well."

Pros: "The plane was spacious and we had really good seats , next to the toilet and wall in front of us. Super, as we were traveling with a toddler and he was able to sit on the floor in front of us and play with his toys. Food came out promptly and was tasty. Loved the goodies for the kids, little blanket and scotch pad."
Cons: "The delay in boarding! It’s hard work when traveling with a toddler."

Pros: "I forgot my laptop in the flight and called almost inertial but could not find it yet."

Pros: "Price, comfort, ice, food and drinks"
Cons: "I just don’t like discomfort of others moving their seat back."

Cons: "None"

Pros: "Very comfortable flight in A380"
Cons: "Boarding at Melbourne was late and somewhat shambolic. Flight attendants did their job but not with enthusiasm or friendliness. Emirates flight attendants seem to have lost some of their enthusiasm and friendliness."

Pros: "The service, food and boarding were all excellent. It brought back the joy of flying like what used to know in the 80s."
Cons: "None"

Pros: "The food was good and the service was great. I also had a great seat in the front row."
Cons: "We were delayed by over 2 hours We had no where to park when we landed so we had to wait for buses to take us toche terminal There was no new and exciting movies that excited me"

Pros: "Awesome plane, lovely cabin crew, overall went above and beyond to make it as best a flight they could for us! I will definitely fly (and prioritise) emirates as a preferred airline from now on."

Pros: "Loved my experience with Emirates. It was the best international flight I've ever had. The seats are comfortable, the entertainment options are great, staff was all very friendly, alcoholic drinks were complimentary, they give you a great care package with socks, ear plugs, toothbrush and paste, and the price was great!"
Cons: "The only negative thing I have to say is the food isn't good, but that's to be expected for me as I'm very picky. I just pack my own food and snacks."

Pros: "Fast"
Cons: "No tea only coffee. No extra drinks. Crew unenthusiastic. Fewer decent English movies. Will be looking elsewhere after 14 years of being emirates-loyal."

Pros: "Extremely quiet plane since they placed people in front of the half empty plane. Great plane food and internet access, limited to text but still incredibly useful to text people from the air."

Cons: "Delay in the take off and the plane was old .. No control from the crew on passengers behaviour which was disappointing.though the flight from colombo to dubai was excellent"

Pros: "Enerttainment"
Cons: "Got moved to right near the galley and crew talked loudly complaining about people, during sleeping time and the light was too bright to sleep. Limited vegan food available. Everything seemed too much trouble for a lot of staff, they were rude and impolite. Delay boarding in singapore."

Pros: "On that route the plane can be quite empty on the Melbourne-Singapore leg, meaning lots of space to sleep in coach."

Pros: "Entertaimnment"
Cons: "Carry on weight retractions and scattered boarding"

The crew were polite, and friendly with excellent customer service. Refreshments and Entertainment were first class. I will be flying Emirates from now on."

Pros: "Comfortable cabin, attentive crew, if somewhat aloof. Food okay, but better than a 2 ounce package of salty pretzel mix for $3! All in all, quite good."
Cons: "Nothing comes to mind."

Cons: "Delayed and passengers not given accommodation. Food also had to ask."

Cons: "Chreck inn staff is not polite to younger student guest. Particularly not to young female guests. I feel the airline is biased."

Cons: "Slow cleanup after food service."

Pros: "Crew very professional. Fare for flight very reasonable."
Cons: "Had 90 minutes fr connection, 30 min delay so 1 hr left. Had to walk walk and walk for nearly 1 hr to barely make it. Airport is TERRIBLE in terms of going from gate to gate- loong walks with no moving walkways. Train is a joke covering very short distance. Once arrived in Boston, took 1hr before luggage started unloading, and then to find out our 4 bags didn't come at all. Staff on ground not courteous, wouldn't send bags to home town in Raleigh. Had to wait till afternoon to get the bags and then fly to final destination. Entertainment system very bad, audio/video stop and go, stop and go- really terrible (though notice some people's screens were working fine)."
