My bet is the best fast track is still to fly Malaysia airlines business class within asia preferably out of BangkokBKK-MNL return will cost you about 650 USD and will net you 240 status credits.So 3 flights and 2k USD will get you gold status from scratch and 7 flights 4.5k USD will get you plat...

I fly MH business class regularly 240 status credits for around 550 USD BKK MNL return via KUL so around 28 return trips for about 15K USD spend
