Yes! They have them at the AA terminal!
The last time I went through (end of October), the machines were functioning, but I didn't see anybody use them (despite horrendous lines).
I'm a NEXUS member but am going to wait to sign up for Global Entry until CBP starts allowing free crossover entry for other "trusted traveler" program members. (No reason to pay $100 for Global Entry if soon it will be free for me!)
