Many thanks for helpful replies.
The HNL trip is in BA First,(transatlantic part), but will not be back on BA till March (BA codeshare ticketed flight) but actually on AA in Club/Business class (new 777 bus in 3J which is favorite already).
So could be BA Silver by then and get double miles or simply stick to PLT (for life allegedly) and get the miles for the next OZ trip!
Yes I know, first world problem!!
