I can transfer 765,000 Marriott Rewards points into 255,000 SPG points
I then can then transfer (over the course of several days) those 255,000 to Korean Air, and with bonuses would equal 300,000 SkyPass miles.
That would be enough for two Business Class seats from Chicago to Bali.
The net cash cost of the flights would be $12,200 USD
1.6 cents per Marriott Reward Point
4.8 cents per SPG point
4.1 cents per SkyPass mile
Is this a reasonable usage of my Marriott Rewards Points?
