Is it possible to provide lounge access for a colleague/friend?

Advise please…
My very good friend is flying next week to Europe with Qatar. Flying economy. Is there any chance I can organise entry to a lounge without being here with him? I am Qanatas Gold FF and have a Platinum Amex and Priority Pass.
Many thanks in advance

Hi Sandro,

If you had more time (unlikely in this case), one option if palatable is you could make this friend/colleague a Plat Charge supp card and allow Priority Pass card (if not given to a supp already).
