Hoping someone with a little more experience can help me out with a theoretical. I understand a QR plat can get access to AS with an Avios or Q Credit upgrade to business class, but can that same member guest another passenger flying on a similarly upgraded ticket?

The t's and c's indicate probably given a platinum perk is "When travelling in Business Class with Qatar Airways, enjoy our exclusive Al Safwa First Class lounge, with up to two guests". with the fine print stating "Member and guest should be flying on Business Class Ticket on Qatar Airways."

TIA.
