Economy
Economy would be my class ( and not by choice ) because of the affordability. In addition, I am willing to fly anywhere if the savings warrants it. Heck, it takes 24 hrs regardless, but I won't do anything over 30 hrs.
On my last trip to Asia, I was very impressed with Air Asia on some of the few hopper flights in SE Asia. The convenience of not being overcharged for booking one way ( very rare indeed ). Hong Kong is a good target departure location hub onto SE Asia.
Thank you.
