I have heard of friends booking round the world fares in either economy or business class for attractive prices. Does anyone have experience or contacts for finding these types of fares (preferably departing from HK but have heard also that the best fares tend to originate in Bangkok).
I used Chawla travels Bangkok before, google them and you'll find they have all possible choices from economy to first world class tickets and some allow to leave from Hong Kong. Hope it's useful :)
