Really really nice! Just a few comments from me below in raw form (they're not politely worded, but I typed them up during a meeting). Very minor stuff.

post 2 section 1 - mention that you cannot change TP reset date, remove reference to PIN (they are no longer allowed)

post 4 section 9 - i would probably remove this reference. This "benefit" is ending in about 6 months and all grandfathered people will go to the normal thresholds after that. People that have that threshold probably know a bit about BAEC anyway so IMO it's better not to confuse new people

post 5 section 2 - This is going to be really unclear for non-native English speakers. "Zip, nothing, nada on EC. Look at other FFPs." I think this is a problem a lot of our stuff has, a lot of lingo and colloqualisms that are intimidating.

post 5 section 2 - the example you have at the end is good but not 100% accurate. you can still have a BA BP but have the flight sold as the AA fligth number and get the lower cabin bonus.
