I’ve always been impressed by the cleanliness of the toilets or, at least, its frequent monitoring, cleaning, and toiletry replacements. The in-flight service by flight attendants is superb.

I’ve always been impressed by the cleanliness of the toilets or, at least, its frequent monitoring, cleaning, and toiletry replacements. The in-flight service by flight attendants is superb.

Glad you had Bibimbap which tasted much better than mesh potato or pasta.

Absolutely horrible. The fight member crew or not very friendly and the food was horrible.

It would be better if flight crew can clearly communicate in english. But they are kind and accommodating. Food is good, especially the sandwiches on the self-serving snack trays. They are better than the ones served. Boarding was organized.

So far one of the good one , whenever I go to Korea , I always use Korean airline .

They could have had more up to date movies/better choice of music.

Terrible experience will never fly Delta again. Delayed flight with total disorganization and inept crew who wouldn’t communicate.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

They texted me my gate number and then they texted me again it’s now boarding but in different gate, and the gate was so far from the gate they texted me earlier. I have to run just to get to my flight. They always do that.

Really good! I like all the crew, they were so nice and very efficient.

Attentiveness by crew was very good. The seats were uncomfortable seemingly too hard with inefficient cushioning. This was verified with my traveling companions. Also the incline button was inoperable.

A great flight experience - great seats, lots of ROOM for legs & in the aisle. Great attendants! My flight cost me the same as ZipAir, the website was WAY less confusing & wonky - this will be my 1st choice for my next Japan trip. Very pleased / well cared for.

The plane was dirty, there was trash in the seat pocket in front of me.

Underpricer was terrible. They wanted to charge me $150 for a seat asignment. Kayak is responsible for letting this happen. Please let me know if this is going to happen in the future. If it is i will not use kayak in the future.

Checking in was hard because we had to enter our middle name with our first name and wasn’t told to. The representative from underpricer investigated it and called me back. We were very appreciative for him.

I loved Ryuichi Sakamoto's OPUS in the movie choice.

Too bad the plane didn't work after we taxied out to get in line for take-off. We went back to the gate and waited for almost 90 minutes for them to find a plane that worked. Waited another hour to board. When we got to Rochester we waited for over an hour for our bags to appear. The agent said they only had three people working to load and unload baggage. A one hour flight took an extra four hours. It would have been faster to rent a car at JFK and drive to Rochester.

One of the best economy flights I’ve ever taken .

Good, not excellent. We’re not informed about mattress pads in business class. My partner ordered food and didn’t get it

Enjoyed flying Japan Airlines! Staff were all nice & flight was comfortable.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

The seats were more narrow than at other lines. Food was mediocre (economy class)

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

Food option Hindu veg to Hindu non veg request was unheard

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

On time, friendly staff and decent food. Would definitely recommend.

My daughter and I had a pleasant trip to Singapore. Reliable and on time.

A 16 hour flight from Singapore to Los Angeles had only 2 meals. It would be great to have 3 meals.

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Had a crying baby and a toddler behind me so it was difficult to get comfortable. Searing was tight even for a relatively small person like myself (5’8” 155). Fast flight but arrived so early the gate assigned was still occupied by another plane so we had to wait for about 20-25 minutes to get reassigned to a new gate and get over there.

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

Seats are smaller and harder than other airlines we have travels with. Food was edible but no good. The sandwich was the only thing I would eat again. They did have a lot of movies to watch.

boarding was uneventful. Snack was pathetic. A tiny fruit bar. Entertainment was limited to just select movies on your own tablet or phone. No live TV. I recently flew Jetblue and they had unlimited snacks and live satellite TV the entire flight. My seat was an exit seat, 20A. It was super uncomfortable. It felt cramped and the middle seat was taken up by a large woman who pushed into my shoulder and arm. Horrible flight.

I liked that the flight to Kosice was on time, the service was excellent and we arrived to Vienna early. The only thing I did not like, is that I had to pay for my suitcase $75. Bummer

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

This flight was a lot more comfortable with more room than the Air Canada Rouge!!! We will never go rouge again! A yes to this one!!! It was so nice to have inflight entertainment! Also the carts came around twice for drinks or a snack!! Great experience all around!

AC flight attendants aren't overly friendly. Otherwise flight was fine.

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

I’m handicapped and the staff and crew were so kind and helped me board and made sure I was fine during the flight.
