Everything about the flight was good or very good. The only bummer was that there was a 2 hour delay and that's not the fault of the airlines but it still takes away from the whole experience. The most amazing thing was that our bags got to baggage claim in record time! That was excellent!

Everything about the flight was good or very good. The only bummer was that there was a 2 hour delay and that's not the fault of the airlines but it still takes away from the whole experience. The most amazing thing was that our bags got to baggage claim in record time! That was excellent!

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

Vegetarian options were not that great. However, the crew and service was awesome

The food was not great and the seats you need a little bit more space to put your things down around you: the blankets and toiletry bag were good. Flight was on time and bags etc no issues

Entertainment was good , comfort on airplane easy hoarding food and drinks was good and a friendly and good service of flight staff

The plane was very clean and the crew was very nice.

The lounge in Japan was busy and smaller. Have great choice of ramen.

Customer service was very good. Food was delicious. Wish the flight was longer.

I didn’t know that my connecting flight from Japan to Hawaii was at a different airport - arrived in Haneda (ticket said Tokyo but didn’t notice the airport name) and had to get my bags and go out of immigration and back in to go to Narita airport 2 hours away. Such a hassle and SOOO confusing and complicated. Check your airports IN ADVANCE and NEVER book if you have to change airports. 40+ years of flying and first time had this. Never again. ANA is great but booking agencies will sell you a connection that you have a good chance of missing - even under the best circumstances.

I was good seat to keep stretch my legs . but couldn’t keep my bag in my hand . because they told me can’t keep my seat is no holder , because no seat fronts of us. wish I can put my leg on something higher. but instead of that everything goood.

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 boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

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.

It was very good. It was a long flight and being a tight with little leg room.

I always fly with Qatar air and you are the best. Keep up the good wor, after travelling with Qatar Air More than 80 times, you never offer to upgrade me.but it happened to my friend companion some time. Any how i still enjoying travelling with Qatar air and wait one day to upgrade me too. Best Regards

All great, because I was given a seat with extra legroom on this part of my trip.
