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.

One flight attendant in particular. Wish I knew her name to commend her. Also, had a bassinet for my grandson!! Frequent beverages offered, especially water. Allowed to move seats once in the air!! Able to help my daughter with her baby. Chicken dish was actually really good.

No movie screens at all!? Odd; especially for an International flight. Check bathroom paper supplies more frequently. Ran out of paper towels two bathrooms. No fault of yours, but the Venice airport was a nightmare. I am use to airports in the US and was shocked how long the line was to get through to our gate. We couldn’t even find the end because it wrapped around like an “S”. Surprised we had to print our boarding pass (but was never asked for it); couldn’t do a mobile boarding pass.

- 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.

one check-in crew (female) at gate was not very nice. My mom is disabled & in her personal wheelchair. The other check-in crew members told us (5 total) to go together to board the plane then this female staff told us we can only have one family member go in with my mom (to take care of the wheelchair then assist her on the plane) next time we board the plane. Their messages are inconsistent & her attitude was uncalled for, especially when she let other disabled passengers on with their more than one family members & the other Asiana staff members told us to go in at the same time.

Relatively comfortable plane, great movies (I watched four!), good timing between meals/snacks.

These planes are always SO cramped. We paid to be in the section with 9 seats across instead of 10 which was worth it but wish that they would just give everyone slightly more space - seems humane for such long flights! The group boarding on these huge planes always seems chaotic. Also it seems like it would honestly make more sense to start at the back and move forward. Would have less waiting for people in front of you to get settled. Wish the last snack had a piece of fruit or something with a bit more healthy aspect.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
