Is everyone in your family up for doing 3 separate trips to Asia? Singapore and Manila are close enough to combine on one larger trip. Required award points for 3 passengers in business class can be quite a bit (millions easily for three trips x 3), even if you can find 3 award seats together for every single segment.

Many Asia countries will take its time before reopening borders for general travel. Monitor the situation closely but don't be surprised if 2022 is a lost year also for some nations.
