Reviving this thread with a related question. I am on a Cathay Ticketed flight operated by Qatar from SEZ to MEL via DOH and HKG. I am happy with the lounge access arrangements in HKG but confused about DOH! I am OneWorld Emerald and the ticket is booked as Business Essential (P Class). Will I get into the Al Mourjan Lounge or should I be aiming for the Platinum/Gold lounges? I note Qatar P class doesn't grant access to Al Mourjan but I am unclear as to if it makes a difference that I am on a Cathay ticketed flight operated by Qatar.
