I don't think I did anything special here.

Then I did the same in the reverse direction, and found 2 that were a little more than a week apart (which was how long I wanted my trip to be). Then I did a search for that date allowing "all partners" and using MLA as the destination instead of LHR (which is where I actually want to go), picked the option that routed on AA for TATL, held it, and booked it a few hours later.

For the outbound, there were a several scattered days of availability in July and August. For the return there was a lot more.

I'm flying SFO-LAX-LHR / LGW-MLA there, and MLA-LGW / LHR-JFK-SFO back, all in J. The stops in London are overnight but less than 24hr. BA for the LGW-MLA-LGW legs; AA on everything else.

Obviously I was extremely flexible with dates (this is a vacation to visit family -- I can go whenever I want) so I was willing to take anything in June, July, or August.

I'm not sure which month you are searching but I found nothing in June (I didn't check earlier)
