Easy. MYY can be the TPAC gateway; SBW can focus on AU/NZ; BTU shall be the O&G hub (nonstops to YYC, IAH, GIG and the Middle East with conveniently timed connections to the oil rigs and KL Simpang airport for Petronas businessmen); MYY can be the island hopper hub, and KCH can focus on the super high yield flights to the financial centres of the world (HKG, HND/NRT, SIN, LHR, EWR/JFK etc)
I think the best business model is to follow those who operates in a country with "continental size + several major hubs" as well i.e. Air China, Air Canada, Qantas and the US3 (United, Delta and American Airlines).
