Most relaxing long distance flight I have been on. And I have flown on many.

Most relaxing long distance flight I have been on. And I have flown on many.

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!

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

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

I was ordered vegetarian food, but didn't services to me :(

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.

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. 😍
