OP, have you contacted AS directly via e-mail or phone or are you relying on the web form? It took me nearly 5 months to get credit for a QF flight flown last fall. However, contacting AS directly about this issue got the miles posted within 3 days of contact. I'd previously submitted requests twice using the web form, but that doesn't seem to work reliably with partners apparently.

You're a MileagePlan member; this is absolutely an issue for AS to solve; you don't need to contact CX (and will likely get nowhere even if you try to).
