Amex travel flight booking and new BA tier points?

[Supersub]

Sorry if this has already been covered but I couldn’t find any info.
With the new spend-based Tier Points, any idea how will this apply to BA flight bookings made through AmEx Travel? I’m about to book a First flight (using the £200 Biz Plat discount) through AmEx Travel for November 2025 but will this eventually generate any of the new revenue-based Tier Points?
Thanks in advance.

I think it’s been said in some other thread. It’s revenue based but you get points on all spend including taxes etc. Points are shared across the people on the booking, so you should only book for yourself if you want all of them.
