First get an Amex business platinum card. Then book flights with your pre-selected airline through Amex travel portal.

$1,000 flight on Amex travel portal

100,000 pay with MR points from your gold card

35,000 MR point rebate (important: only if you have Amex biz platinum)

Net: you spent 65,000 points for $1,000 ticket

which means 1 MR point = $0.01538

so 1.5 million MR points ≈ $23,000

good for you
