Seats are not table comfortable. Crew members are pretty good. Can be much better!!

Very pleasant overall, although the movie selection could have been better.

Very pleasant experience overall, while the main course of the meal could have been better and the movies could have been more recent and with more variety.

I usually have ear problems when planes land. But the landing was so smooth I didn’t even notice it landing! The service was excellent!

the aircraft was fine and new. The crews can have better training. Their operations are not as smooth as EVA's. They are VERY stingy with drinking water. Throughout the entire flight, no one offered me any water and snacks. I still prefer EVA after trying out Starlux initially with lots of excitement and expectations.

Everything was smooth and professional. They could improve the raw vegan meal with fresher offerings, but otherwise they are now my favorite way to fly to Asia.

Leg space is small. Need more room for long flight.

Leg space is too small. Need to increase space for long flight.

Amazing!!! It really is good! The seats do go back far to relax so if you don’t like the person to go back, just adjust and go back and everyone goes back to settle and be comfy. Enjoy few free drinks and the little amenities they provide.

This Airline is really good! Better than Eva air for sure and more luxury. I really liked all the small details and amenities plus it really is free alcohol!

Staff was so nice and very helpful with directions aswell!

It was our first time flying with China Airlines and had a very nice experience. The airline staff & crews both on the ground and air were very nice. Food on the plane was very good. Will recommend it to family and friends.

Not great, will likely try to fly another or maybe I should have upgraded my ticket? Needed Air…

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

My ticket did not indication which group I was in for boarding; the gate attended help me

Very routh cabin crew food is only 2 meals for 13 hours fry with them They should get better training how to service good super routh language and talking with customer

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.

Boarding could have been a little bit better but other than that it was a pretty good experience. I think because of the stowaway to Paris France recently they are being extra diligent about boarding passes at the gate. But they boarded the back of the plane first, and that's something I really think needs to start in the USA.

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

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

get E+, a must for 5 hours flight if you are tall

The first flight was better in terms of the aircraft.

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)
