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

I missed the flight. I never got on. That sucked.

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.

Great. Better than average US carriers on overseas flights. Still room for improvement to rise up the average Asian and Middle East airlines.

No food at all so it was a bit of a culture shock for international travellers with connecting domestic flights.

It was excellent except for at the very end. I woke up about 1.5 hrs before touchdown and wanted to order food in the Business class. I was told they had shut down food service. It would have been good to get a heads up before they closed the service. Anna the air hostess was wonderful. She did get me 2 bowls of fruit and I was very appreciative of her. Wonderful human and a hostess.

Amazing airline accommodations. The cabins were so great. The food was very good and the flight attendants were so nice. Made a 15 hour flight seem easy.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Qatar Airways is an excellent service provider. The crew members were attentive and helpful. The aircraft was very clean. This was the longest leg of our journey, so it would have been nice to have more leg room for comfort. We appreciated the crew's service of four hot meals to all of us during this long flight. Also, it was helpful that the crew asked us to keep the window shades down for the entire journey, allowing the environment to get lots of rest during the trip. For families traveling with little children, this was helpful to them to keep them settled.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Vistara i bought a biz class fare but a few days before vistara always changes my biz class flight to economy .. happened to me 4 times .. seated could be wider .. boarding could be more organized .. crew did their best but not enough resources all in all very poor experience Qatar Delhi .. only complain .. no clear signage to lounge for transferring pax .. its a Delhi shot coming.. no feeling of exclusivity for biz/ 1st class pax.. but everything else was much better .. once i boarded Qatar .. i loved it Qatar to Washington .. only complain i boarding .. too crowded .. no separate area for biz/1st class should hav completely separate area for upper class.. security is stifling pax comfort by the gate ..but everything else was great

Crew attendants attention to the travelers. Good food. I always fly with Turkish Airlines

The sleeper seats, the staff, and the food was truly delicious. I loved the mocktail options.

Great food, and lots of it. They made us come to the gate two hours before the flight and you were stuck in the enclosure until you boarded with no bathroom or food or drink. My seat in business class was very claustrophobic, I could barely get into it and a large board blocked the window and made it even more claustrophobic

Cabin was kept very hot and it was uncomfortable. Entertainment system did not work at my seat. Crew and service is fantastic

The crew on this flight provided exceptional business class service to me.

The airport staff never announced that boarding has started. Both at iad or Islamabad or Istanbul.

The airline could improve its business class seats and privacy in line with its competitors.

The seats have to be one of the worst when it comes to comfort and you have to scramble around to out your handbag in the overhead. The food is still awful. Definitely will not travel on Turkish again and wouldn’t recommend it to anyone for sure.

Very happy with the service, comfort, and food on Turkish Airlines. Security and check in was great.

Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

Bad check in experience. Dirty ancient aircraft. Truly awful food and this in Business/ First class.

I truely appreciate all services. I was highly impressed and will not hesitate to recommend United Airlines to friends and family. The AVML was perfect.

Very kind Lufthansa agent somehow gave us all no charge extra business class seats and helped us get home rested and happy.

The lounge was not accessible because it was located before the passport control, and backtracking was impossible.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

Entertainment center did not work and no electric available at seat for 11 hour flight. Didn’t have access to overhead light or call button. Food was tasteless and had a high salt (27 %) of recommended daily salt intake

What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

The flight was canceled. I couldn't get on another flight. Meal voucher wouldn't work. The whole experience was a clusterfuck.
