As it's an award ticket, I suspect that the airline can do what it likes with the "fare basis".
My guess is that "BA" does stand for British Airways, because I've seen BAEC awards for partner airline start "PA", possibly for "partner".
But F does not stand for First. I see BAFM01 on the shortest short-haul economy awards.
ISTR that the last two digits have something to do with the length of the flight
But that's about all I can speculate about.
Sounds interesting. Thanks for that insight. Never knew that Airlines do it like that. IIRC, Lufthansa doesnīt use it like that. The thing with the feeder flight booking in J is logic, as the Fare base is based on the main portion(e.g. longhaul flight) of the journey, so when you book a First class fare itīs A... or F... with a feeder in J.
