This is the problem for me. I will be flying somewhere and there will only be a Delta club but I will not be flying Delta. So I have the US Plat card AND pay for Priorty Pass.

The other problem with the US Plat card is travel outside the US. If I'm flying Virgin Atlantic I can't use my Amex to get me into any clubs in London. Priorty Pass does get me into clubs.

I would rather have the a Free Priorty Pass like the other non US members get.
