Yes, I can see the offer in my Amex Experiences app "the great upgrade". I have a Silvercard, with around 10k spend. However, I just can't personally justify spending €600/year on a credit card. Got a good travel insurance already, the additional XP makes it easier to renew my FB Silver, but there are cheaper ways to do that. Wondering why they didn't opt for a 'tier upgrade structure'. I might for example be interested in a 'big upgrade' to Gold with say 30k/points? Silver to Plat is a big step.

Also I discovered this weekend I never received my annual 15XP for the Silvercard around February. I called Amex yesterday, they made a 'case' for FlyingBlue to investigate and correct this. Anyone have some experience with this, does it help to separately contact FB?
