The key question is who operates the flight : AA or KE? If AA, no SkyPesos even if booked under KE flight number. If KE, you will earn miles if booked under an eligible fare. Whether they will be qualifying, I'm not sure with all the changes done by DL those last 2 years and especially for KE. You can surely see this on DL website.

Where you book a ticket doesn't matter at all.
