I would like to commend the staff from this flight. They all looked happy and I can tell they love what they are doing and constantly smiling while serving the passengers. Special mention to the guy FA in our section. I did not get his name but he is so far the best F.A I have ever encountered!

I would like to commend the staff from this flight. They all looked happy and I can tell they love what they are doing and constantly smiling while serving the passengers. Special mention to the guy FA in our section. I did not get his name but he is so far the best F.A I have ever encountered!

staff are super nice and effiecient! It was a very comfortable and relaxing flight

When I booked a premium economy ticket. I then had to pay $100+ to book my seat.

Didn't like on this return inbound flights (from Hong Kong to Vancouver) Outbound to the Hong Kong was good.

I did not take the flight, tried to cancel it right after I booked it, but was unable to reach anyone. I blame Kayak for this situation because they sent the booking through another company and I was unable to get anyone to talk to me about the situation. I had to just take the hit and pay for another flight through Cathay Pacific, which was wonderful. I will never use Kayak again. (I bet they don’t post this review!) I’ll just post about them on social media sites. I don’t want anyone to have to go through the hassle and expense I dealt with.

Airline itself is great. While food was being taken off of my tray my beer spilled which was a total accident and I wasn’t upset about that, what was frustrating was I had to ask for towels to clean up and wipe my leg. It would have been left as is if I hadn’t.

Bars and restaurants in Taipei close early. The lounge isn’t very good, but better than the public areas.

The food was the only thing that could have made the experience even better. Everything was stellar but the food. The staff was superb. I’ve been flying with ANA for years as my go-to and I think I may have found my new favorite. 😍

Not many selections for entertainment. Bulk head seats are no longer available with out fee at the counter. That’s pretty lame.

All of the staff were very helpful, polite I was very satisfied with China Airlines The food was normal for airlines but I’m sure they could do better

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was very good experience on board to Sydney with SQ.

Everything was great keep up the good work 😁, can't ask for more.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

The food options and quality could use some more excitement and variety.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

I was a member of Krisflyer for ten years, but my last flight to Tokyo was a disaster. I had to stand in line for four hours before check-in because they were late opening the counter, and there were more than 50 people behind me. The plane was extremely small, and the food could have been better. When I dropped off my stroller before boarding the plane, I expected to receive it upon exiting for my transfer. However, they returned the stroller to the checked baggage because they said I was late getting off the plane. Of course, I was late; they assigned me a seat at the back of the aircraft, and I was traveling with a baby! The worst part was when I arrived in Jakarta. They damaged my stroller and refused to approve my claim, so I had to pay for stroller rental because of the damage they caused. I don’t know what happened to Singapore Airlines, but I felt like I was flying with a budget airline.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

I have taken this flight many times. It is ALWAYS late. Every time there is significant delay (1-3 hours) before boarding. It’s very consistent. Even after boarding the expected landing time was delayed twice. The seats are very narrow and cramped. Food is barely editable. Considering an economy ticket often costs about $2,000 it’s one of the worst services ever.

Boarding was over 3 hrs late and we didn’t land until almost 1:30am

I disliked the fact that they forced people to put up their seats during meal service

Everything was great from the staff to the seats and food. The plane was timely taking off and landing.. I couldn't have asked for a better experience (especially on such a long flight)

The service was excellent. The quarters were a little cramped in Economy, and we had to exist there for 18 hours.

Flight is overpriced. Quality of service is poor. Constant delays. This flight again was multiple times delayed. The relaxed and careless attitude of staff is appalling. People are busy and it does matter if we do things more efficiently than chilled out. Once the flight was ready to depart we had more delays due to the careless approach of boarding passengers. Food is highly processed with limited options and super unhealthy. Leg room is shockingly bad. Even the biz class is pretty bad. Coupled with the horrendous prices Qantas only benefits given Australia is their home market. Otherwise they are not competitive at all.

Great flight and attendants. Seating is a bit weird. The extra price seats aren’t too worth it.

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 crew was very helpful to my family, especially when my daughter became sick during the flight. Will fly with them again.

Enjoyed the flight with attentive flight staff. Thank you Qantas.
