My flight to Los Angeles was canceled Had to book another flight and you charged me extra $500 Very bad experience

My flight to Los Angeles was canceled Had to book another flight and you charged me extra $500 Very bad experience

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.

The plane was uncomfortable. I paid extra for more legroom but the seat was still uncomfortable. Other seats on the same exact row didn’t have to pay extra but still have extra legroom. I didn’t understand why I needed to pay $170 for. It was Iike China airline just wants to make money off their passengers. It was unfair.

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!

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 check-in crew at SF did not put on breakable glass stickers on check-in baggages which caused my antique whisky bottle to break during transportation.
