Very poor experience and will never travel with JAL again. With Business class ticket i was told that there is no veg option for the 1st leg of my journey from Delhi to Tokyo while served horrible plant based meat on the second leg of journey even though i selected Vegetarian meals. Also entertainment system is worse than domestic flight with hardly any Hollywood movies and no hindi movies at all

Staff were friendly and awesome! Some Filipinos are just undisciplined, but not an airline problem.

Good. The only thing is that I missed the flight.

Food we select all the airlines, but they said not selected, it’s bad experience.

My seat was so hard and uncomfortable. I took AA to Japan longer flight no tailbone pain. Coming back on JA shorter flight my tailbone was killing me no cushion on seat or just worn out.

Not very much of anything, it probably was once of my least favore business class flights I have experience in all the times that I flew Boz class

I always enjoy flying with Japanese Airlines. The whole experience is always a pleasure. This flight was no exception. Thank you Kayak for making it so easy to decide.

Very smooth onboarding and offboarding. Food provided was cold and not the best.

Terrible experience. Staff would not even refill my tea once. While they refilled a fellow Japanese persons wine 7 times. They also lost my luggage. Horrible. Go elsewhere

main courses of the primary meal were not good- the beef dish was really not good-

SQ service is great as always. However, the food quality seems to have gotten a lot worse recently.

Best service airline. The cabin crew is attentive and friendly. Inflight entertainment system is good

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.

The staff were amazing and very kind. The seats recline a little too far back and are up close when sitting behind.

My groups frequent flyer star allianceUnited airline miles was not accepted. The Singapore premium economy bag had to be requested, it was very lacking- no toothbrush. I paid more than double than economy but could only use the bathrooms sharing with economy which was hardly available and had to wait in line. Is the 2X $ worth it just for a larger seat???? It is questionable. Seats were not that comfortable. My husband’s seat had white stains on it- had to wipe it down. Our headphones did not have covers on it. Food- way too much.

Awesome! Was impressed with the hospitality and the thoughtful services. The cabin attendants were superb.

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

It was a super smooth and comfortable flight even though I was in normal economy. The staff was so nice ☺️

Seamless fussy free flight. Great service as expected of SIA.

I would not have changed anything… It was a perfect fight

Seat bottoms were not good, hard to sit so long. Food this time was bad. Crew were absolutely excellent. Plane was good and clean. 30kg checked bag weight limit is very convenient. Price is very good but seems to be rising lately. I'd would like a value plan (check bag and seat selection) but without meal. Is also like better upgrade options, once I purchased my tickets there was no option until boarding gate or after take off, but price of upgrade was still high.

Good budget airline. Disappointed zipair membership program doesn't let you transfer your 30% discount to your family members.

Punctuality is a great factor. Boarding, departing and landing in timely fashion. No hazles and very profesional service in land and during the flight. Great experience.

Wifi never really worked. Flight attendants were generally fine except when they were not very helpful when my wife accidentally spilled a soda (they chastised her to apologize to the people sitting behind when it was dark and we couldn't see anything and they brought one tiny napkin to help clean it up). Seats were uncomfortable for all four of us. Otherwise a typical flight.

Seats in economy might too narrow. people sitting next to each other is always hitting shoulders.

Easy to board and fly, no frills. Yummy ramen on board.

Couple of the crew members were really nice and the rest are really rude and didn't help when we needed help, food was not worth it at all and most importantly there's no even entertainment system other than a very interruptive and slow internet and some movies.

internet didn't work. No offer of drinks or snacks.

Internet connection very poor, means you can not even order items through their own shop.

Een prijsvechter, dus dat moet je ook verwachten. Voor alles moet je betalen. We hebben vooraf een maaltijd en een amenitiesset besteld. Die kregen we netjes uitgereikt aan boord. Het is BYOD voor het amusement tijdens de vlucht en dit werkte uitstekend. Geen trage wifi, helemaal niet. Alles kost geld, zelfs een flesje water. Misschien op langere vluchten wel gratis water, thee, koffie. Maar daarentegen mag je na de security je lege drinkflessen gewoon vullen en mee aan boord nemen

Thanks to the kind staff for locating my lost onamori.

Quite ordinary, as might be expected of a budget flight. It was difficult to understand the instructions unless one speaks Japanese, and the seats were quite basic.

Very easy process overall. The staff communicated well and everything was efficient.

Very affordable, smooth check in process, flight attendants were safe and kind, lots of flight availability within Japan.

The seat is so bad Can’t recline the chair

For Travelers with babies, if they can be supported by allowing to carry the Baby stroller upto the Airplane gate, and not submit at the Check-In counter. it will be very convenient. Thankyou.

Crew, friendly On board services: terrible: no movies, no screen, no entertainment over wifi, no free water. Totsl Entrapment

Boarding was not as per sequence Light snacks were not available Window had hair oil stains and water condensation

I have taken more than 50 flights in the past year and this is the worst onboard experience that I've come across. There's always a risk with budget airlines and their creative views of customer service. Having bought a standard seat, we boarded at the assigned seat - we naturally couldn't choose ourselves as that would be extra cost. After take-off, the person in the row in front leans back their seat. As a frequent flyer, I believe this is their right, so I try to lean my seat back as well to have the same space available. However, my standard seat could not lean back, as the row behind was an exit row. As I had paid for a standard seat, not a less space than standard, I moved to the completely free row behind me. This was not allowed, as due to extra legroom, this would cost extra. Subsequently spent the next 30 mins discussing this scenario with the crew. I have no issues with budget airlines and additional charges, but if I pay for a standard seat, I want a standard seat, not one with less space. As you do not offer me a discount for the less space, do not try and charge me a premium, when I find a free seat with more space. It works both ways Scoot.

Boarding took forever. It's also weird that we paid more (for preferred seats) to get on the plane last. Inflight WiFi never worked the entire trip. I want my money back.

The cosmetic condition was pretty run down. The carpets were badly worn out. Even the paint on the wings was chipped and peeled! Looks like they are running these 787s to the ground..

WiFi didn’t work on both sectors so made killing time harder - planes clean modern and good flight crew - would do again if WiFi works

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

It was a cheaper flight and it arrived early. I thought the crew were pretty noisy for an overnight flight, and my friend was not able to sleep because of the noise. Also I think it’s absurd they don’t provide complementary water. Why does everything have to be a surcharge? Airplanes are dehydrating and it would be beneficial to help passengers stay healthy.

I paid an additional fee for specific seats because I was flying with my two children. I even checked in online and confirmed my seats, so at the airport did not think to double check my seats. The lady at the check in desk gave me different seats that were not together, nor did she say anything, even though she could see I was flying with children. Got to the plane and only realized what had happened then. Scoot refused to refund me that extra fee or take responsibility for what had happened.
