Please read the ULTIMATE sticky and do a search!
Look, the easiest thing to do is just forget all the silly letters which
don't offer points and full miles. It's far easier to just remember the ones which
do and then you can infer the rest if needed. The following will give you full points and miles for each class:
FIRST: F/A
Club: J/C/D/I
World Traveller Plus: W/T
Economy: Y/B/H
Each listed in decreasing order of flexibility. Any other fare class gets you no points and 25% miles, except the redemption (X/P/U/Z) classes which get nothing at all for obvious reasons.

I appologise for any inconveiniece I may of caused, how could I have not instantly understood the blatantly obvious fare structure of BA.
I hang my head in shame.
PS - My original Post included is an extract from the Sticky. I did look first.
