Ex-expats who rejoined years ago left for another local outfit and the remaining "others" will join Air Asia in few months time to include most of the qualified Captains.
This is a negative implication of BUPAK's current situation.
There is a deeper problem other than Dondie and Sayong and they are
just incidental or accidental to the situation. If Bupak's management will continue to play
"CHEAP" with their most precious posessions,
THE PILOTS, the situation will recur as a system cycle even if all of them are EXPATS.
When you are
very tired and very sick due to heavy loads of flying and nobody in the Flight Opns that you can lean on and your pay is not enough to compensate you, then it's time to consider
"ENOUGH IS ENOUGH". Goodbye Dondie, Goodbye Sayong, Goodbye Dan, Goodbye Sam and Goodbye Lance...Happy & Safe Flying to All!!! (Who left you) 
Take your lead from EX-EXPATS, they will show you the way.
