Most of them are OK! But, meals service was not enough. I felt hungry after eating the meal for the first time. I had to buy some other food. So I had to buy a sandwich and drinks for the return flight. And I am not sure it's only my feeling or not, I felt my butt is getting forward. I will use Korean Air or Asiana Airline for next time to visit Korea.

Plane and service were great. The entertainment is only for Koreans. Wish there were vegetarian options for food. All in all pleasantly surprised. Economy premium was quite good.

This form doesn’t work. Can’t type in, had to copy-paste. The crew constantly telling everyone about minor things is unnecessary. Did you put the belt on, push your bag more under the seat… The seat space was good for tall people, the food was decent for airplane.

Roomy seats for the given price! I couldn’t ask more!

Great airline, but there was no English entertainment (movies or shows)

Check-in was an absolute disaster, taking more than an hour and half because they offered no online check-in and Kiosks were not available to use. In-flight entertainment was exclusively Korean media with a selection of only 5 or 6 movies to choose from. Korean television shows were also available. The food was lackluster. My chicken and tomatoes had 3 small pieces of chicken next to a mountain of soggy wedge potato fries. The seats were more comfortable than other airlines I’ve flown with and the staff aboard was extremely pleasant and helpful.

One of our luggage items was damaged during our flight to Newark from Incheon. Although our email communication was not responded to, when discussing the matter with the staff at the Newark checkin before our return flight to Incheon, we were provided with a free replacement luggage item. This customer service was, overall, very satisfactory.

I would have enjoyed some hot tea, preferably green tea, but they only serve hot coffee.

10 Hours delay on departure of the return flight and in-flight Wi-Fi was not available entire flying time all that caused monetary loss to my business.

Some favorite food ran out of service and I have to eat what was left available. Also I had to drink cold red wind! Why could not have been kept in room temperature?

Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

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.

It was a 2 hour flight to Taiwan. Lunch was served. China Airlines goes above and beyond for their passengers.

Staff is friendly, great variety of entertainment, check in a little messy but due to people not listening. Overall a pleasant experience. Would use again in the future.

It felt like a new plane. Decent leg room in economy, food was fine, and the plane didn’t feel super dry and uncomfortable.

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

Baggage made it successfully to destination despite short layover. Appreciate that.

Flight was delay almost 2 hours from Hong Kong to Taipei. Last minute gate change from 24 to 66. Long way walk. We need to run in the Taipei airport to catch our next flight from Taipei to Vancouver. That is so suck!

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.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

There was a loud squeaky sound the whole time we were flying.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

Honestly, I didn’t expect that I will experience this long time wait during the check in. There was only one person who was taking care of the passengers for the economy class and it took us to wait about one hour to do our check i. As a result we barely get to the airplane as the gate was at the end of the airport. That is totally not professional where one crue is working at the registration desk with economy and 3-4 crues are helping for the business class.

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

The crew was quick and efficient. The flight was uneventful and arrived slightly early.

My seat was broken I couldn’t put it back I have really bad back issues , the flight was 5 hours delayed and there was a drink dude harassing the entire flight

No food or entertainment because it was a short flight. Unfortunately the takeoff was delayed more than an hour

The flight left and arrived on time. the only food offered on the 5+ hour flight was a cheese sandwich. Unlike Alaska Airlines there was no information on the website regarding food at all or any option to purchasse in advance. Otherwise, it was an excellent flight.

Parents with kids should all be in the same area. Sounds rude but who what's to fly 6hrs with crying and bratty kids. Just my opinion.

Ok, so I didn’t have seats, so got there very early. I was first in line only to be told, listen for your name for seats. The flight was boarding before they gave me a middle seat, way after others showed up who were given more favorable treatment. Ok, so , don’t show up early and obey all the rules??? Clearly, your gate clerks did not. What gives???

Short flight but delayed. Since its a short flight no food or entertainment necessary

We had an awesome flight attendant who came by and made sure we were okay. Checked on us often and even shared some snacks that she had brought on, like edamame with chili and garlic seasoning. Yummy!

Overall good experience. I'm just over 6ft with long legs and legroom could be better, but is on par with other airlines. Only real negative was turbulence but that's not the airlines fault.

We were not given the seats we reserved. But helpful attendant at gate gave us very nice seats.
