slightly off topic but..

would i be allowed to use any ("most" as stated on dl.com) ST lounge as a PM when traveling internationally in y or do i only have access to the designated lounge. just flew out of HKG on DL and was given an invite to the QF Biz lounge. i'm now thinking I should have also checked out the nearby KE lounge (i heard it's not very good but that's not the point).
