Had the opposite problem recently, QF8 was not showing in the lounge screen at DFW in the AA Flagship lounge. Qantas has a dedicated customer person here and I asked them about it - noting that other OneWorld AA codeshares on Iberia and Qatar were showing fine. Their response was that they complained to AA IT many times who said it was a Qantas IT issue.
Incidentally the Qantas station chief at DFW couldn't pronounce Canberra correctly and incorrectly informed the passenger in front of me that they didn't need to collect their bags at Sydney as they were checked all the way through to Can-BEAR-a. Fortunately the passenger understood when I jumped in to clarify they would need to collect them prior to Customs in SYD, but if this is the kind of training they're giving to the person supposedly in charge, no wonder they couldn't get the IT fixed.
