Well it would be 30K each way per person to upgrade to asia in a B/Y fare. So you are spending 2-3k on those tickets.

To use an award ticket it is 60k RT per person for a perksaver coach ticket which is hard to find. 120k RT for biz class for perksaver

i beleive SJU is 15k each way to upgrade to FC, i do not remember what fare class a base member can upgrade out of.
