I'm sorry if this is a poor question or if it's been answered already but I couldn't seem to find a recent answer through search.

I'm planning on booking close in J/F on ANA in February but I've been learning that AC / VS do not have access to T-21/14/7 award availability?
Is booking ANA on ANA the only option for award booking? Also, how do people find out which partner airlines have/ do not have access to ANA award flights?
