hi ff community - i've been searching through the forum for an answer but to no avail..

I am flying from slc - ams and bcn - slc with delta/af.
I've brought a domestic ticket from ams - bcn with Iberia.

I am a skyteam elite, and have an amex plat (with priority pass select card). What will be the best shot to get me and a guest to a lounge in AMS?

Thanks so much in advance guys!
