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

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!

Better training to have qualified crews and services. My flight was from around 12 midnight Friday Taipei to Vancouver. After two hours first meal (2:00 Am -8:00 ) no crew available for even asking for some water. I was even willing to pay for water. For breakfast after 8 hours the only drink was tea and coffee no water or juice.

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.

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

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

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!

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.

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.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

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

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

Transfer within the same terminal and lots of facilities at the airport.

Even though it was a very full flight, the service was still excellent, the plane did not feel too cramped and cabin crew made a sincere effort to help passengers find overhead space for stowing luggage.

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

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

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

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

The plane was new (<6mos old) and was very well appointed. Lots of places to store things/plenty of legroom/comfortable seats/great blankets and headsets. Food was very good too. And crew were all very friendly and accommodating. Great trip!

We were delayed for 7 hours. The staff and management could have organized the getting of seats on later flight earlier than 20 minutes before late takeoff. Everyone was worried and lost. Was chaos and it didn’t need to be.

The catering forgot our baby meal for my 1 year old

couldn't work out how to work entertainment. seats a bit cramped.

flight delays seems to be the norm these days. pies with soggy pastry.

Overall a positive experience. As long as you are not connecting-I found the discount offered by Kayak and the customer service to be very good.

We were downgraded from business class to premium economy with no advance notice. The staff at the gate were extremely rude, the crew on board not very interested in our comfort, mostly stood in the galley and talked with each other. The food was about the worst I have had and the portions were small ( and I am not a big eater). altogether sbout as disappointing an experience as is possible

Polite staff but incompetent staff. They changed my window seat to isle seat and then lied saying the seat was broken, yet I see someone else sitting there! They lost my luggage. Their standards have dropped a lot compared to pre-pandemic.

Everything went solid and was on time. No issues at all
