I had the seat 48A which was next to the emergency exit and no chairs front of me which made me very comfortable. Also I can drink anything i want as much as I want.

Out of the whole 13 hours flight we only had 2 meals which was not enough for me. I was hungry between the two meals during the flight so i asked the flight attendant for anything to eat and she gave me 2 hot peice of bread. I accepted without complain.

Nice new airframe, for what that's worth. Staff are attentive, friendly.

Atrocious legroom & my legs are NOT long; like being in a stress position entire haul. BRUTAL. Flown many airlines to SEA, this was so bad it shocked me. The food (every 'meal' was poor, gross all-around but the "bacon & eggs" ....the egg didn't taste like real egg, bacon left raw. Inedible. The one exception was the chicken breast, that was actually a good standard... but they never have enough for everyone, and the rest of the meal was inedible. Almost no snacks offered, variety of drinks non-existent.

The crew on The flight was efficient and friendly.

The flight was so crammed. I understand there's the possibility of flying on a fully booked flight but if it took an hour to load the passengers how quickly can you realistically get 400 passengers out? Plus it prevents everyone from having an overhead cubby. You need to reconfigure the flying experiwnce.

Very short flight so not much to comment.

Not that I didn’t like, but there was no entertainment and no beverage on this flight. Maybe add a “N/A” as an option in the survey. Flight was delayed, but we were kept updated.

- The check-in counters opened at least 30 minutes late. The agents arrived late, they seemed to be having a good time and didn't feel the need to explain the reason for the delay nor apologize for it. - On my flight to Manila from Los Angeles, I did not check in any luggage. I had a carry-on and a backpack that fit perfectly well into the overhead bins and underneath the front seat. On my flight from Manila to Los Angeles, I was not allowed to take the same set on board because the total weight exceeded 7 kg. This put me in a bind because the heaviest item I had was my small LCD monitor which was in my backpack. I had to put it into the carry-on with wheels which I had to be checked-in. I would have prepared to carry it in my backpack because it is a fragile item. When I was told to sign a document that absolves the carrier of any liability for the checked-in luggage and I refused, the China Airlines Duty Officer in Manila informed me that unless I sign the document, my luggage will not be loaded on the plane. I felt extremely frustrated by the attitude of the Duty Officer who didn't hesitate to threaten me and insisted that the rule was imposed on them by the TSA in the US. Instead of helping me work out a solution to the difficulty I was facing, he simply walked away with a dismissive attitude.

The fact that my father was diagnosed with Cancer and they wouldn’t refund our 1300.00 for round trip tickets to the Philippines which is our vacation home. The airline required documentation from my fathers doc which I provided. He was not going anywhere for at least a year (radiation and chemo) and the denied even credit.I was able to get my parents tickets refunded by a different airline. NEVER Again. my father passed 8/12/2018. Our trip was scheduled for 9/13/2018. Very disappointing.see
