I'm seeing some as soon as Oct 19 (MSP-LAS). Florida routes seem to be coming in November. Note that there are 21-day advance purchase and Saturday night stay requirements.
I fly to FLL 2 times a month - it is pretty standard for fares to drop in November and then in Dec they add 2 additional nonstops a day so availability goes up. Still, I do not recall ever seeing the E fare!
