Actually I have not.
But I did think of four more that I would be extremely surprised if any AFFer has ever been to.
1. KJOT - Joliet Regional Airport
2. KARR - Aurora Municipal Airport
3. KLOT - Lewis University Airport
4. C09 - Morris Municipal Airport James R. Washburn Field

How soon is she looking to travel? Is 2 stops okay? TK are selling MAN-IST-KUL-ADL with the last leg on MH for ~£2,559, which isn't cheap but it's about the same as half a return
T4 check in agent said AA were no longer paying for the space in TBIT. This was back in August but I pretty much only remember seeing DL service desks post customs on the ground floor. I know there were a couple other airlines as well, but definitely no AA
Unfortunately I think your chances are extremely slim. CX aren't selling any non-stop seats HKG-SFO on either 20 or 21 April.
I'd be asking them to potentially re-route via LAX
