They finally released the seats the morning of the flight. Kind of bizarre. First they said the waitlist was closed because there were so many people on it. Then over 15 seats become available in one shot (so what happened to the waitlist?). Problem with airport standby on a connect is if you run late the folks who either get there ahead, or originate in the hub, beat you to it. All in all, the system seems to be very uneven, particularly as compared to other carriers.
