Airline reviews

Pros: "crew was professional, attentive and polite"

Pros: "Sky Time drink was interesting. Flight was on time."
Cons: "More leg room. Better information on what is included as far as meals / drinks."

Cons: "No service. No drink, no snack, flight delayed. Missed last bus from airport to station at base where stationed. No happy"

Pros: "Sitting in my seat I felt that I had wiggle room for my feet and my arms/elbows. Usually on American flights, I feel like a sardine packed in a can. Even though I was in economy I had plenty of space and was very comfortable during 9 hour flight from BKK to Tokyo."

Cons: "Tight seating."

Pros: "The flight attendants were very attentive and polite, seats are some of the most comfortable of any airline I've flown (particularly compared to the US domestics), entertainment is solid (although the English movie selection was not that large), and we were regularly offered food and drink if we were awake. I would definitely recommend JAL to others."
Cons: "The food was not to my liking (i.e., all Japanese style, but not necessarily types that appeal more to Westerners) but it was palatable."

Pros: "The flight from Chicago to Tokyo was delayed, which made me worried that I would miss the connection to Taipei. I was very happy to discover that an airline staff person was waiting for me when I got off the plane, having already changed me to another Taipei flight. She explained things and guided me to the right place. She was able to walk amazingly fast for a woman wearing high heels!"

Pros: "JAL is hands above any of the American airlines....so polite, helpful, diligent and graceful. Food much better as well, and newer planes."

Pros: "Polite friendly and attentive Staff. From checking in to inflight."

Pros: "Crew was really professional and friendly, I sat beside a mom with 2 kids and the crew really helped her in her needs and made sure we were all okay. Food was good and I loved the movie selection, watched all the Oscar movies I've missed."

Pros: "Great service."

Pros: "Service and airplane are the best!"

Pros: "Their customer service is excellent! when I left my card (fell out of my pursue while in transit), they called me immediately! After a long vacation, exploring. I was extremely tired and and left my phone completely on silent for 4 days, and within those 4 days they called and left me messages. Lucky I live here in Hawaii, can you imagine being a tourist and you lost your card? Excellent customer service."
Cons: "Nothing"

Pros: "Lots of room in premium economy, good entertainment selection. Clean bathroom ! Excellent service. Food was mediocre."

Pros: "The service, more leg rooms and flight attendants were very friendly."

Pros: "Nothing"
Cons: "Everything. Screens were small. Leg space was little to none. Food was trrrible. I will never fly with JAL again"

Pros: "Seat spacing good for economy food was good"
Cons: "Movie Selection"

Pros: "The food is good. The seats for regular economy are a bit more spacious. They also have some deal with fast food restaurants, Mos Burger and Yoshinoya so sometimes you can get their air version of the fast-food meals. I had Yoshinoya and it was pretty good. The entertainment was okay, the only 2 things I wanted to watch was John Wick 2 and Guardians of the Galaxy 2, but the movies change every month so it was probably a bad batch. Also free toothbrushes and toothpaste available on the plane and a self service snack area. Overall it was great."

Pros: "JAL always have good services."

Pros: "Crew service responsive and helpful."
Cons: "Poor vegetarian meal (mostly vegan rather than vegetarian and without condiments). Problems using entertainment screen, which would get stuck and also have to go through many steps (confirmation screen, language) to see maps each time."

Pros: "Friendly and helpful staff, excellent food."

Pros: "Sakura lounge was excellent."
Cons: "The entertainment system was bit unsteady."

Cons: "I reserved Korean air but it was Japan air line. I was really difficult to web-check in to find my reservaiton."

Pros: "As expected from JAL, the flight was amazing in every way. The food (the Japanese meal) was not typical airline food, it was actually very good. The courtesy packets had many useful items including eye refreshers, lip balm, and the bathrooms were kept very clean and stocked with both mouthwash and toothbrush/paste. All together as flawless and comfortable an experience as possible on a commercial carrier."
Cons: "There was nothing I didn't like, but if I could make a suggestion it would be to offer a larger selection of movies and shows on the long-haul flights. Also the cabin twmperature was a bit too warm but I understand that might vary from flight to flight."

Pros: "Courteous and helpful crew members and I liked the delicious meal served during our flight."
Cons: "Nothing."

Pros: "Great flight, great staff. The food wasn't bad either."

Pros: "Except for the tightly packed seating in economy class, everything else was beyond excellent. And even that was better than some US domestic flights. Large selection of Hollywood movies, gratis."
Cons: "I laughed at the Brace For Impact illustration on the safety card. It was not possible for me to double over with my arms under my thighs. The seat ahead was too close. The headphones produced tinny sound, and the two-pronged plug precluded using my own."

Pros: "There was a huge amount of new and classic movies to chose from to pass the time. The crew was friendly and professional. The food was decent. I like the variety of food choices and some of the dishes were delicious (salmon and rice). The seats are pretty comfortable. They aren't great for sleeping in, but the flight was decently quiet and dark for some time. I would recommend bringing a pair of earplugs and a neck pillow."
Cons: "The bread could be better. I would have the bread be softer and warm. A warm croissant as a substitute would be amazing.The butter could be softer (like margarine) so that way it can actually be spread onto the bread."

Pros: "Boarding was orderly and crew was nice and polite."
Cons: "The person in front of me reclined her seat entire fought crushing my knees and leaving NO legroom, couldn't even use foot rests!"

Pros: "Staff- the ladies in flight were very friendly and courteous."

Pros: "Good service, good food. On time arrival. Comfortable seats. Great airline."

Pros: "Seats in cos are comfortable and plenty of leg room compare to US airlines. Food selection is very good as well as the service. Flight Attendants were very friendly and attentive. Will fly JAL again!"

Pros: "The crew and service."
Cons: "No entertainment. No snack either."

Pros: "Flight was very good. Entertainment and power on new Dreamliner is excellent. Food - better than the hot dog we received as a meal on the LAX-KIX flight. Still just ok overall. Seat comfort is ok but more recline - at least in premium economy."

Pros: "Crew did a first-rate job, and space in economy seating was civilized. Snacks and juices were tasty and plentiful. Bathrooms were spacious and waits for access were manageable. Television screens and headphones in economy were easy to use and reproduced video and audio content well. Overhead storage space was adequate, even for an almost fully-booked flight whose passengers relied upon it very heavily."
Cons: "One of my vegetarian meals (the larger of the two) wasn't vegetarian. This was astonishing -- a first for me in more than twenty years of flights across the Pacific. Not once have I had a vegetarian meal that included chicken, but that is just what was served to me on this flight; I was obliged to spit it out, and to wash my mouth afterwards. The selection of films offered was demoralizingly poor, and the seatback pockets afforded even less storage space than usual."

Pros: "Excellent custumer service including cabin attendants' attentiveness and pilot's warnings of turbulence. Great in-flight entertainment. I liked the special touches such as the small snack and water bar available throughout the flight, and the breakfast Kumamon special. Clean bathrooms are very very appreciated."
Cons: "The only bad experience was when we were boarding, and I asked whether I could take a newspaper and the business class flight attendant snidely said that it was only for business class. I understand the comment, but her expression and tone were unnecessary."

Pros: "JAL ' service is nice."
Cons: "I didn't like MSG in food."

Pros: "Big bathroom, bide, wifi, movies, very good coffee, spacious seating areas, the price of airfare!!"
Cons: "Everything!"

Cons: "My seat was not comfortable and it was uncomfortably warm."

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: "Crew was very pleasant professional and caring."
Cons: "Seat bottoms could be more comfortable."

Pros: "Cathay and JAL Provided excellent customer service throughout the the flight. Everyone did an excellent job and went out of their way to make sure I made flights and had what I needed."

Pros: "excellent seat space and excellent in-flight service."

Pros: "Crew service"
Cons: "Food and not so updated movies in entertainment."

Pros: "Courtesy of crew members"
Cons: "No vegetarian food available"

Pros: "Service N crew n entertainment."

Pros: "A quiet, quick and on time flight in a small plane with a competent crew - just as expected!"

Pros: "This complaint is more targeted at American Airlines, which handled the New York Washington leg of the trip. They provided free food such as sandwiches and drinks at the gate due to the 2 hour delay."
Cons: "Red eye flight delayed for 2 hours. Then delayed another hour on the runway. No in-flight enternmaint, which would have made it bearable. Descent into Washington Reagan National freaked me out because the plane was flying eratically while being so close to the ground and recognizable landmarks."

Pros: "Very polite and fast service, international Languages"
Cons: "Food was a bit boring and bland, but since it was only from Seoul to Tokyo, it was okay. But I was hoping for Japanese food instead of that Egg dish, the entertainment system needs to be updated since the touch screens had a delay of about 10-15 seconds or didn't even function at all."

Pros: "Crew was very helpful"

Pros: "Staff were accommodating and considerate, great flight!"

Cons: "Qatar Airways could improve food selection for business class."

Pros: "Crew was amazing"

Pros: "Amazing aircraft! Amazing crew!"

Pros: "The service is really good. The only downside is that you have to be in Doha. But it’s always nice to leave Doha."
Cons: "The push button entertainment system doesn’t work well. You have to keep pressing buttons to make a movie play. And by pressing buttons, I mean, you have to hit the screen and wake up the person whose head is on the other side of the headrest."

Pros: "Excellent service on both flights. Truly a 5 star experience. Well done Qatar Airways."
Cons: "Nothing. Keep up the good work"

Pros: "Crew was very polite and helpful."
Cons: "Quality of food could be better Hindu meal was not as good as expected"

Pros: "Convince, as this is good direct flight from Nagpur."
Cons: "Improve quality of crew and service from Doha to Nagpur sector."

Pros: "Qatar Airways could not be described except a FIVE STARS airline. Great hospitality and respectful crew"

Pros: "Crew was not this great on my Flight from Doha to IAD. My pre ordered food was not given on time and they missed it. I was given cold food. The flight attendant ignored to offer Drinks and they didn't give the Custom Forms too. I have to ask everything and THE overall service was awful"
Cons: "Flight attendants should care the passengers and provide the best service. Otherwise there is no use paying expensive flight tickets and travelling on Qatar"

Cons: "Seat comfort"

Pros: "The Crew were excellent, friendly, professional and attentative."
Cons: "We checked in seven and a half hours before this flight as we had just flown from Melbourne Australia to Qatar landing that same day at 0435am in the morning with this flight being delayed from 805 am to 12 noon then to find that we had been allocated the last row right at the toilets. Horrible."

Pros: "wanted an isle seat because of back issues and was arranged without any hassle."
Cons: "17 hour transit in Doha and no accommodation was provided. Though I booked it from a third party I belive QA is at least responsible for making sure that the vendors let the user know that there will be NO accommodation provided. This information is also not readily accessible when searching online."

Pros: "The leg room was huge, the food was excellent and a lot and the customer service was great not my first time to fly with Qatar and it won’t be my last, the made my trip worthwhile. Thank you"
Cons: "No complaints so far so good"

Pros: "The cabin crew was fantastic and made the experience very positive."
Cons: "The food was not of the quality I would have expected from the expectation created by the airlines marketing."

Pros: "Crew were very helpful and courteous"

Pros: "Air hostesses are classic.The plane very spacious ."
Cons: "Wait time to connect from Doha too longNo hotel accommodation."

Pros: "everything"
Cons: "nothing"

Pros: "quick eficient"
Cons: "long flight"

Pros: "Food"
Cons: "Bathrooms"

Pros: "The service on board is excellent"
Cons: "Nothing"

Pros: "Nothing"
Cons: "Theyt cancelled my trip"

Pros: "Staff was outstanding"
Cons: "N/A"

Cons: "I’m a 6’3” in shape man. I selected the bulkhead seats for extra leg room. Great crew, but my shoulders stuck past the seat edge 3” on both sides."

Pros: "Overall services"
Cons: "Checking in was very lengthy and boring. More check in counters could ease the situation."

Pros: "Good, drinks, service and entertainment system."

Pros: "The Qatar Airways price."

Pros: "childrens meals and play packages. service was good, and bathrooms were kept clean. The meals were tastey and fresh."

Pros: "Enjoyed the food and the service from the crew. Plane was new and relatively new and comfortable."
Cons: "The check in agents were not very polite or helpful. They did not offer much assistance and help for a first time customer on Qatar Airways. My bags were also not loaded onto the plane and had to arrive on a later flight"

Pros: "All the services were excellent. From the checking-in to the boarding. The flight crew could not have been more helpful, courteous and polite. Food was great on board."

Pros: "Checkin was really quick, needed to have some facilities for the passengers who have more than 8hrs layover."
Cons: "The crew was not efficient or always looking for shortcut. The specific person assigned never recommended or gave any information about the amenities available rather was waiting to be asked uneasily and was not polite at all. Need to be trained more effectively for such a 5 star airlines."

Cons: "The chicken sandwich was horrendous. I saw multiple people take a bite and then put it down and not eat the rest. It tasted terrible."

Pros: "This flight had one of the best selections of movies I've seen on a flight.....a damn good thing given the 15-hr duration of the flight. I had so many screaming babies around me that the flight attendants helped me to move to another part of the plane. They were incredibly sympathetic and accommodating. Airlines from the USA could learn a thing or two from Qatar Airlines."
Cons: "Small seats (I'm fat, so this is my problem really)."

Pros: "Good legroom with respect to others airlines.. the plane is clean.. multiple bathroom so no long waits Dinner was tasty.. however the breakfast was not."
Cons: "Cheap headphones will not isolate sound from airplane engine for such an expensive entertainment"

Cons: "No WiFi"

Pros: "Good, newer wide body aircraft. Good service. No hassles, really. Would fly again. Overall good experience."
Cons: "Newest seating arrangement in 777 300 ER just too crammed. Used to be better. Nothing special about this flight, was expecting a little more space, a little less crowded, a bit better service. But my flight was short hop from BKK to HAN, last leg of flight originating in Doha."

Pros: "My daughter gets airsick and one of the staff in particular was so helpful unlike some other airline"

Pros: "I travel a lot and the employees were the best I have seen in over 20 years. I had special needs and they were very attentive."

Pros: "2 bag checks allowed and being giv n th option to check in an additional carry on at no charge."
Cons: "Boarding was hodge-podge. Seats are way too close together for a long haul...person's tray in front of me was in my face the entire trip and she didn't bother inclining throughout so had to eat my meals like a contortionist. Cramming more seats into a finite space seems to be what all airlines are doing these days. This of us whom are above average in height are forced to insure a more painful and uncomfortable flight as a result."

Pros: "Very spacious, good food & service"

Cons: "Boarding was horrible with those disorganized people that keeps telling you please sit while waiting for the gate to open AND THERE IS NO SEAT (in front of the gate) SO THEY ASK YOU TO SIT WHAILE THE NEAREST SEAT THAT AVAILABLE ARE TO FAR AND THEY ARE ALL OCCUPIED."

Pros: "Food was good."
Cons: "I didn't appreciate the fact that Qatar opened so late at the Abu Dhabi airport, nor did I appreciate that the woman who printed out my boarding pass royally screwed up and printed gate 8 , when in fact it was gate 3. That was total BS. Supposing I missed my flight due to her negligence ??"

Pros: "Spacious single seat Plenty of handy storage Pajamas provided Quiet cabin Great service Lounge wonderful as ever Not woken until last minute"
Cons: "Boarding a bit haphazard"

Pros: "Service"

Cons: "Service"

Pros: "After long takeoff delay, made up most of time to land less delayed. Bagge arrived more quickly than I EVER experienced a Hamad Airport."
Cons: "Boarding started very late so we knew takeoff would be delayed. Flight attendant woke me up from sleep to ask if I wanted breakfast."

Pros: "Brand new and beautiful A350 aircraft, great service"

Cons: "Same old tiny uncomfortable commuter jet."

Cons: "First time we have flown First Class on American Airlines and service was outstanding and perfect! Thank you for an amazing experience!!"

Pros: "Timelness"
Cons: "More leg room"

Pros: "Seat uncomfortable. I am an elite flier and was put in an n uncomfortable middle seat with no choice."
Cons: "Seat should with choice."

Pros: "Nothing"
Cons: "Handicap issues. We were exiting on the tarmac in Charlotte- all crew left us on the plane waiting for assistance to get off. Finally when someone showed they would not come up the ramo to get my Mom. I backed her down myself while 5 bewildered airport workers looked confused."

Cons: "2 hour delays on both flights of a round trip"

Cons: "4 hour plane availability delay - of course planned on weather but not planning"

Pros: "On time"
Cons: "Having to walk from concourse b to concourse e for my connecting flight in less than 15min before the doors were shut. Was literally in my seat for 5min and the door was shut. Most people (older or families) would have missed it. Shame on CLT or American Airlines"

Pros: "On time. Friendly and attentive staff."

Pros: "A cheap option to upgrade to 1st was offered that ended up being a net 0 cost upgrade for me so I took it. Comfortable on an old (but oh so nice) aircraft."
Cons: "Arrived 30 minutes early to the airport but then had to sit at a remote pad so that we ended up being 5 minutes late to the gate. A short transfer was made even more difficult, and a massive waste if time and fuel sitting and waiting. Figure out your gates early and better, and move around if needed. At the very least, bring up some stairs and buses to get passengers to the terminal and then tow the aircraft in when you have a gate available."

Pros: "I fflew Delta last Nov. Had meals movies dinner inks etc. American I am serv d beverages no meals and no movies. Getting ridiculous"

Pros: "Room between rows Entertainment from St Louis to Phoenix"

Cons: "Flight was cancelled with no compensation"

Pros: "Fast"

Pros: "The crew was great"
Cons: "The seats were not comfortable and boarding was a pain. Not sure why you wouldn’t want to board from the back to front. Weather grounded us at our loading airport so we were stuck with the option of staying the flight or going in the lobby."

Pros: "The pilot was great. Avoided turbulence and arrived about 20min early. Easy to find seat and stow bag. Smooth takeoff and landing."
Cons: "Alaska airlines was who I thought I was riding with but the itinerary changed past min. Gate change and the airline itself was changed. Really confusing since I printed my boarding pass the night before."

Pros: "Everything went smoothly."

Pros: "The flight was what one would expect from a domestic airline. They did provide free movies/tv which was nice. It was one time to leave and on time to arrive."

Pros: "Quick boarding, on time departure and early arrival. No waiting for a gate at LGA upon arrival - excellent."

Cons: "Flight connections time was not enough for mam with infant.we missed the flight should better set up that kind of big airport"

Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."

Pros: "Spacious seats"

Pros: "I was so happy I could check in online and boarding was a breeze. I actually got to sit by the window when my original seat was in the middle. So nice of the ladies to suggest it to me."
Cons: "No complaints"

Cons: "The video monitor for my seat was broken. So, low entertainment score."

Pros: "everything was on tyime"

Pros: "On time take off"

Pros: "A nonstop flight, with a friendly efficient crew, met my expectations. A crew member went above and beyond when I asked for a coffee stirrer with my coke and ice."
Cons: "I've been spoiled by another airline's access to screens on the back of the headrest. I have my own hand held devices to entertain myself instead."

Cons: "Delayed a total of four hous!"

Cons: "good"

Pros: "Flight was on time, staff was friendly and boarding was organized."
Cons: "I'm a small person (5'-2", 105lbs) and I didn't have room to breathe in that tiny little seat."

Pros: "Smooth - trouble free - calm process"

Pros: "Arrived to the airport well ahead of time and encountered lines so long that we were not able to make our flight. Only 2 attendants working and so many people had to be rebooked we didn't get another flight for 3 days. Did I mention I was traveling with a baby?"

Pros: "On time arrival"
Cons: "Everything else"

Pros: "Nothing"
Cons: "The storage are very small, by the time i boarded everything was full. I had to hand carry bags and i had to put it in front of me which is a very small space already, on top of that i had the window sit so i had no space to move. it was very uncomfortable, and flight was delayed. We sat there for an hour before taking off but i understand its due to the weather but it was my worst plane ride not worth 300dollars. I will not ride american airline again."

Pros: "JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't."

Cons: "Everything was great."

Cons: "Only suggestion would be to make the connection process a little easier. If the passenger doesn't speak English, the fact you need to print the international ticket in Miami, then re-enter at checkpoint might create confusion."

Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"

Pros: "On time. Good leg room."
Cons: "Valet flight, i.e. even normal sized carry-on cannot be stowed above the seat We arrived at the gate 20 min before departure, due to TSA delays. But they closed the door and no one was around to even talk to. At least they put us in the next flight.... Still, as we're not checking in any bags, they could have let us in."

Cons: "Got to charlotte with 80 minutes to connect. Sat on the tarmac for 60 waiting for a gate. Missed connection by <5 minutes. Thanks, AA!"

Pros: "Non stop"
Cons: "Airline"

Cons: "Boarding took forever, the flight was over 2 hours late which caused me to miss my connecting flight and my military orders were not honored - I still had to pay extra to take all my gear back to my duty station. Never had that issue with any other American airline."

Cons: "No food or beverages for me. I slept comfortably on my flight"

Pros: "I don't know how airlines get away with all the stipulations and regualations they have in the buying process there is. Otho g I like about the scam artist they are"
Cons: "The fact they they can just make it a policy and then because the employees have to have a job and enforce it blows my mind. 200 dollar transfer fee plus the difference in the ticket when it's over two weeks in advance. You people are scam artist"

Pros: "You provide me with the best ticket prices and to me that was the the most important part of of the trip thx"
Cons: "The airlines charging for your luggage"

Pros: "Plenty of leg room no entertainment so I dozed."
Cons: "People stuffing oversized bags in overhead."

Pros: "The movies"
Cons: "No Food"

Pros: "Frankly there isn't much to say here. After 7 flights in 2 weeks there was only 1 flight with great staff that actually cared about the customers and looked like they enjoyed their job. The rest treated guests with indifference at best."
Cons: "Customer service is dreadful, the planes are so old they still have cigarette lighter charges in first (but of course no adapters), no food/snacks of any significance, and they seemingly cancel flights at a whim with basically no staff to help re-book the lines of guests that have been disrupted. I pity those who loose luggage AA baggage services are flooded with lost baggage they just don't care any more. Seriously its embarrassing how little they care about customer service."

Cons: "Flight was delayed."

Cons: "Would be nice to know ahead of time if flight is equipped with an in seat television so as to be prepared to bring headphones."
