Well, rumor has it that FLL-SFO is one route slated for launch fairly soon. Maybe that has to do with FLL-OAK being slashed.

And yes, this schedule extension certainly helps us figure out what "big announcement" will occur in October. With one frequency being cut on JFK-CMH/RIC/CLT/RDU, BUF-BOS, and IAD-LGB, JetBlue is going to have some flying to make up for if it wants to keep its fleet utilization high. Methinks that the E190s operating those routes are poised to go to the West.
