American Express Membership Rewards - PTS and IAP of different countries

Hi everybody,

I am based in The Netherlands and I hold a Platinum Amex. IAP here is offered for certain airlines (NZ, AZ, AA, CX, CO, DL, EK and TP) and certain routes.

IAP in Italy comprises some other carriers (among others, AF and KL).

Can I call PTS in a different country (in this case, Italy) and book something with them? Can I use the IAP offers of another country? Has anyone experienced that?

Thanks!
