Options for VS miles
 

I currently have a ANA J round trip to Japan from US in March that i rescheduled to Nov 2021. My wife and I are expecting (yay) but from a traveling viewpoint i'm very sad about not being able to utilize the ANA J soon.
we plan to travel maybe in the next 2-3 years but we're unsure of here the partner programs will be with All Nippon after the recent delta axe.
Do I have any options besides constantly rescheduling my ANA J flights ? with the updated taxes and 2 ticket vouchers i had to pay around $170 to rebook

I rather not let my points just sit in idle and wait for more devaluation.
Is there a way to convert an award booking to an actual ticket voucher? (i know im reaching here)

I'd schedule long haul ravel when your kid is still an infant and before s/he starts walking. That tends be very easy compared with a 2 yr old. You likely need to cancel the ticket and rebook - based on the ticket validity.
