I don't know who changed the WIKI but I could verify that the QR Al Mourjan Lounge in DOH is currently accepting oneworld Sapphire/Emerald ( BAEC Silver/Gold/GGL/Premier ) members traveling on Y despite the operating oneworld carrier so I'll be re-modifying it. Passengers are able to choose between the Oryx Lounge and the Al Mourjan at their own discretion.
Also, unfortunately I have verified that the BNA AA Admirals Club access needs double-security for BA passengers ( when BA starts to re-operate ) so I have removed it from the list.
