The general rule of thumb is if your next flight is a QR operated flight in business, irregardless of how the ticket was issued (ie codeshare, upgrade, light fare), as a plat you will have access.
Agree here. As long as you are a QR plat and flying on QR metal it doesn't matter if it's a code share or another airline ticket. Have flown on LATAM (non one world airlines) ticket to Sao Paulo on QR in business and been accepted into Safwa lounge no questions asked.
