Trying to find (3) award seats using SM to SE Asia during peak season? And at a reasonable redemption value? Since DL no longer flies their metal to any SE Asia cities that means almost no chance of a last minute Flash Sale using SM either. So....good luck....
I'm going to BKK in January and had to redeem AA for CX F LAX-HKG-BKK then used AmEx MR for SQ J BKK-SIN-EWR. Not a single seat on ANY routing on ANY day in J at anything resembling fair value using DL SM's for the months of Jan/Feb/Mar '24 when I searched earlier this summer.
