Decent flight, staff was very good, especially with the turbulence during the flight due to weather. Comfort was about par with other airlines but since it was a quick flight, was not much of an issue for us.

Decent flight, staff was very good, especially with the turbulence during the flight due to weather. Comfort was about par with other airlines but since it was a quick flight, was not much of an issue for us.

Liked that I could pick my seat and have a special meal without an extra charge. Luggage is reasonable for overseas trip. What could have been better is boarding and leaving on time.

They were helpful, considerate with asking us for standby preboarding with our infant, gave us toys and excellent service onboard. They were always on time, even early boarding once! All our luggage arrived intact, and they even brought our baby car seat to oversized for us. We love China Airlines!

Great flight, although I flew out of ONT and that is where my car is, lol

3 of the 4 flights had delays despite the weather being fine, but still managed to make all connections

Ask flight attendant for water during flight and she was a little rude get the water.

Staff were good and nice. There should me 3 meals instead of only 2 and snacks.

Excellent staff made the boarding process fast and easy. Friendly crews on both flights from Saigon to Taipei and Taipei to Los Angeles. Will fly China Airlines again.

For a long-haul flight, the crew did a very good job of keeping the lavatories clean and the aisles clear.

The plane was an older model and the entertainment was hard to enjoy on those small screens. I struggled to see clear anything I wanted to watch. The seats where a bit uncomfortable but for a 3 hours flight it was pretty ok. The rest of services were excellent. Highly recommend China Airlines to others.

It was a great flight Food was great Crew was spectacular

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

They close their counter so early. I had internet issues so I couldn’t check In online . I would have made the flight but their counter was closed 5 minutes before we arrived. No way of contacting them even though I had the confirmation number and tried to check in the night before on someone else’s phone. I tried calling their customer service with no pick up. Horrible experience, I’m very unhappy with them. I hope to never fly with them ever again. It costed me almost $900.

The stewardess was very helpful all the way. My seat had an issue with headphones and after the replaced and gave me a new pair and noticed it was the seat I got a new chair to sit and a great ride back home

The seat comfort, the food and of course the crew, they made you feel welcome and relaxed 😊

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later

Flight delay was informed at the last minute. Food quality is not up to Qantas standard I was unable to book an online boarding pass on any of my 6 flights.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

1) crackly headphone jack 2) one of the emergency seats recline. Usually second row does. But in this case neither did 3) food was scrambled eggs or fruit. 4) fruit should not be the option to eggs 5)miserable unpleasant crew not a smile. Thought that was a virgin thing

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

Enjoyed the new possibilities of in flight entertainment. Been awhile since I've flown, and that was a nice surprise. Being able to pick from such a variety was personalized and welcomed.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

My bag didn’t make it but otherwise it was a great experience.

Experience was great. My only advice is to have a pasta dish on the menu. Otherwise everything was excellent.

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