Yes, that is the point I'm making. I'm well aware it's the mistake ex-CMB fare, but what does it actually book in to in terms of fare buckets (I don't know, I didn't book this one up myself)? The price is irrelevant. But if you book in to C or J on the BA legs, you can select a seat, whatever you paid.
