Plenty! Besides the access to Dan lounges, you get access to US airways lounges (regardless of which airline you're traveling with), access to AA's Admiral club lounges as well as Delta's.

Priority Pass membership with the first 3 entries free (this is where my UK based Platinum card beats the Israeli one as that gives me full PP membership so unrestricted visits).
In addition you get the Platinum Fine hotel and resorts service which can be excellent value, and many more which you can find here: https://www.americanexpress.co.il/22151.html (in Hebrew but you can use Google translate...)
