Best options for BC BOS to Vietnam with points?

Looking to fly very early Jan (2-4) 2026 to Vietnam. Ideally from Boston, but can reposition to wherever we need to. This is going to be a 2nd honeymoon for my wife and I, so we need to lock our travel in as we are going to do an adventure tour and it leaves on Jan 5. We want to book BC,and looking for the best routes to target. Ideally looking for something with the better BC suites like JA, CP, AF, ect ect. What are my top 3-5 airlines I can start off with?

I have checked SA and they are waitlisting for everything 1st week of Jan and rather than logging into 10 different airlines, I thought I would ask the brain trust first as to what programs to look at first.

Thanks!
