hello all, i am planning a trip to vietnam in dec. 2013. i would like to use my miles and fly first class with my wife and 2 year old. while flying cathay would be ideal, i have been advised to keep my options open. has anyone flown first class from lax to vietnam on china air? how was your experience? i have an old back injury that restricts me to sitting in a reclined seat for only a couple of hours, so i will need a flat bed. does anyone have pictures or trip reports of china airs first class?
