Best Mileage program for Redeeming on Thai.
 

Which miles and points program offers the best redemption for J Class on Thai Airways? All Advice will be much appreciated. Thanks!

One way or return? Which route or routes? Different programs have different sweet spots and restrictions.

One Way. I am looking at CCU-MNL.

What programs do you have points with?
Where are your cards issued? Each countries transfer partners differ as do the rates of transfer

For US cards:
Amex MR transfer to Aeroplan & Avianca both of which should be 50k miles plus $50-$100 USD in taxes & fees.
Chase UR transfer to UA which should be 50k miles plus about $20 in taxes
Citi TY transfer to AV, SQ, TG & BR but you'll have to do your own searches to find out the award chart and fees.
