The guest doen't need to be on a Skymiles itinerary for admittance, just have a same day ticket on any airline. Was just able to guest in a colleague in BRU to the BA lounge even though he was flying UA J to ORD, and I was in DL Y to ATL. However, they wouldn't give him a wifi pass; luckily I had an ethernet cable so I was able to share my wifi connection over to him :-).
