Some buckets will have been paid for through work and so therefore I might have taken advantage of higher ones on occasion for the higher earning (where nothing else was available, naturally). So this is what I think I've been through with BA:

First - not yet
Business - J, D, C, R, I
Premium Economy - E, T
Economy - Y, B, H, K, L, M, N, V, Q, O, G

So still F, A, W to go - and i can't recall any previous flight that booked into S. I'm positive I've had a G at some point just because it looked unusual at the time.
