Paying large CGT with Bluechain and Amex

[TimP]

Hi. Looking for anyone who has done this. Bluechain says Amex imposes monthly limits when using Bluchains services. Amex insisted they do not.

I’m not looking to pay all of it of course at 2.2% fee, but might do £10K on plat for bonus (once) and get 2-4-1’s on 2 x BA cards then pay the rest with Curve/ Barlclaycard Avios, but at only £3K free a month, that won’t come close to paying it all.

Any advice on best strategy gratefully received, thanks.
