I'm really struggling to find the answer to this, even in other posts- I hope someone can help!

On 21 Dec. I will be travelling on EK6 to LHR-DXB.
Then 22 Dec. EK725 to DXB-DAR.

Then 3 Jan. EK726 DAR-DXB and
4 Jan. EK5101 DXB-LHR (this flight operated by Qantas)

My question is, with the new Qantas/Emirates merger, where do I stand in terms of Aadvantage miles? I should be getting AA miles on DXB-LHR flight, as it's OneWorld operated flight, correct? But what about the other EK flights if they are marketed by Qantas? (But even so they were purchased through Emirates.) Does that do anything for me as an AAdvantage member? Do I need to get on Emirates or Qantas FF programs instead? Help-- thanks!!
