I'll take any of this with a pinch of salt.
Everything said about BA's plans either doesn't come to fruition; you end up get screwed with "enhancements"; or by some miracle, the cheapest touch up option.

If they do bring in revenue based tier points, along with reductions in F cabins, who is going to be using a newer / larger CCR anyway?
You would expect a reduced number of F fliers, GGLs etc. if people are needing to pay top dollar out their own pocket (although i expect more people will happily drop £10k for something that was £1k the week before)
