Ah, well I was actually talking about all the physical classes I've booked as opposed to the individual revenue buckets (that was just an attempt at a clever thread title)... but now you've got me thinking - I've never actually written them down but I have always paid attention to what I've booked because naturally it impacts cost. 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.

No doubt some of you will have the full set plus other letters that have been discontinued years or decades ago (what did Concorde use?) so if we are getting geeky here... anyone want to show their hand?

EDIT: what did the babybus book into when it earned First TPs? As I'm now wondering if I may have got F or A by default...?
