Hi,

I am in planning mode for next Summer (June or July) to SGN (Vietnam) flying out of LAX. I have the points to transfer to Singapore airlines for 4 business class (2 adult and 2 child). The reward is available with layover/stop over in Singapore and we're okay with that. The current rate is 128k per person in the June/July. I was curious if there is another option outside of booking through Singapore directly. I search with BA and had no luck. Can anyone offer other recommendation that I overlooked?
The point is coming from Capital one and Citibank via a transfer.

I do have miles with Chase and BA as well if that helps.

Thank you in advance!

PS: Prefer business class if all possible - celebrating the wife's 40th birthday.
