I'm still not sure it makes sense for me, but I'll do some sums tomorrow.

Has it been discussed whether the distinction between the CE bonus and CW will be drawn based on the current definition?

Presumably the 80TP band is no longer.

As BA codeshares on AA etc. are explicitly included, do we know if the business bonus will be awarded based on a 2000-mile threshold for the 400/175 divide, similar to 140/40 old TPs?

I can see the 50-flight qualifying option for Silver being useful to some.
