IMHO, the Skyteam offer to Asia is a very good one (I am at the present time in BKK, leaving on thursday to SGN) :

- Delta from the USA, which has a very interesting network ;

- AF to Vietnam (direct with one stop, with *A I would need to change at HKG or BKK) ;

- KL to Indonesia ;

- KE to Korea ;

- and generally speaking China Southern which is a very good Chinese company.
