You've posted this before and I still am shocked. I'm batting probably 90 something % and the ones I have missed are last minute IAH-DFW flights which seem to have 40 people on the waitlist and one DFW-DEN flight that was J0 when I booked it.

It may be worth dropping a note to AA to just have them check. I had a 3 month period a few years where I either wasn't on the UG list or was in some absolutely incorrect position (and I know because a PLT friend cleared at the gate before I did). Now, it may just be your husbands travel patterns and EQD thats causing this, but 3/18 seems shockingly low.
