Welcome to FT also
Depends on where you want to go for your Honeymoon - I'd personally not fancy PVG, nor do I think it counts as SE Asia.
KUL did have a lot of initial availability for reward seats when first released, not sure if this is still the case?
I'd look to go KUL, SIN or BKK (which may be a 787 then?) as more SE Asia and not too tricky to get flights into the more traditional honeymoon locations from there.
PS - Congratulations
