But which ffp have you credited those flights to?

Delta points do not expire
Conversion VA to KS is at 135:100. You loose a lot of value. Better to burn directly. 56,252 VA =41,668 KS. Starting a new non USA ffp does not seem sensible
UA (6,895 ) is in Star Alliance. If living in USA earning some UA miles is not that hard
BA (1,332) can be kept alive with 1 eligible AA or AS flight ever 3 years. BA awards can cost 7500 avios

USA based airline ffp's tend to be more generous (status benefits/earn/burn/upgrades/award cost/award cash surcharges/expiry/affiliated credit card ff mile earning/promotions) compared to non USA based airline ffp’s (even after the recently announced changes to some USA ffp’s). But if you are not flying the airline of your ffp the useful benefits are somewhat limited.
