I don't believe you can walk between Terminal A and any of the other terminals airside so that might scupper the use of Priority Pass in any of the other terminals.
I don't know the setup in ATL but perhaps you can use the UA lounge pass there, if BOS doesn't offer the opportunity!
Have fun and good luck!
