Long haul from Chicago to Tokyo was great, traveled in the ROOM on ANA and experience was great all around. The flight from Tokyo to Bangkok was fine. Definitely a good way to go. Should have stopped in Tokyo for a bit.

Long haul from Chicago to Tokyo was great, traveled in the ROOM on ANA and experience was great all around. The flight from Tokyo to Bangkok was fine. Definitely a good way to go. Should have stopped in Tokyo for a bit.

"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.

The flights with ANA were great. The flights with United, not so much.

Attendants were very kind and frequently offered water and snacks. Food was excellent. For some reason, my IFE system would not play dialogue for any media despite my efforts to change to different language voiceovers, restart the system, etc. so I could not watch any videos.

Staff at gate and crew on plane efficient and friendly.

As always, there is that one or two flight attendants that could be better.

It was good. The crew was efficient, food was good

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

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

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.

The biggest problem was that I originally had a seat in the first row of premium economy as I had booked months earlier. I checked in and my boarding pass showed the seat in the first row as I had specified. When I got to the gate, the agent took my boarding pass and changed my seat to one in the last row in premium economy against the window. I had specifically booked the first row early for the legroom and for my ability to easily get out and use the restroom when I needed, since I do that quite often. The gate agents explanation was that the food tray on the seat in the first row was not working, so they gave me the seat in the last row. However, when I got on the plane, somebody was sitting in my original seat, and they sat there for the whole 14-hour flight with the tray working perfectly well. I was cheated by someone at the Cathay gate in Hong Kong. It was an outright, unforgivable lie by the gate agent or someone else at Cathay Pacific. I think this is very poor and inexcusable conduct by the people at Cathay Pacific. Perhaps somebody paid the gate agent extra money (bribe)to switch my seat and make it very difficult for me, or something else, but t was a sad experience and a very negative mark on Cathay Pacific.

Good. However the passenger in the search next to mine kept coughing. When we landed in Dallas we had to pick up.bags instead of going strait to the destination (which passengers do in Atlanta)

Check in was awful.., Desks gone….it was a cheap chaotic environment not the usual seated staff member not there….instead a staff little platform…(staff were good) the whole thing reeked of cheap penny pinching- underwhelmed

In between two meals period they're not providing something like banana / cup noodles or bugger. It's really fell sad that I was asking have to wait for 3 hours for second meal. (breakfast)

The crew are timely, friendly and professional. I was very impressed.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

The go to HK trip will easily giving jetlag, but coming back to Chicago has no jetlag because of the time taking off matter.

Just want to do a little more clean up so does not smell like urine.

Wanted different plane design with an additional bathroom at the back of the plane.

It was ok, but not what it was like 20 years ago

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

Very good as always, stand out airline. The passengers whom choose to stuff baggage that otherwise should be checked-in is a real bother but that's not the airlines doing. A real frustration that passengers just don't want to check-in luggage. This is a pet hate unfortunately.

I got upgraded from economy to business, and the experience was outstanding

It was very nice. I will try to fly with Qantas whenever I can.

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

It’s a very long flight and there are so many people on board. Perhaps a warm washcloth now and then to freshen up

The staff we fantastic and seemed to work very well with each other

Better food, hotter coffee, otherwise it was a very smooth and reasonably comfortable flight.

IFE didn't work. Wifi didn't work but they eventually managed to reset it. Our original flight was cancelled, so rebooked onto new flight seated apart from travel partner.
