Hi guys, i have just recently achieved *G through UA P.Ex. (at least i think so, as UA current website states me as such with the needed miles! however UACO preview website still states me as *S and offers me to buy up to gold!

)
Anyway, the question is:
I'll be travelling with Ms. BRflyer in April, however, as it will be my first international trip this year not in J but being *G, I was wandering if she could use the priority boarding along with me! Anyone has had any experiences with that?
It seems to be it should be allowed, as I do not see a reason they would allow +1 guest in lounges, but not allow the companion under same booking reference to use *G check-in and boarding, anyone has got a different thought?!!?
Thank tou very much guys, BTW, we'll flying JJ GRU-EZE!
Cheers!
