I don't have any idea what, if anything, is happening beyond the obvious no-furlough/23A. But with another airline supposedly returning 60 JFK slots, LAX likely having significant gate space coming available and/or EWR having expansion opportunities, JB could well be on the hunt for resources to quickly fill out those voids.

As I said a few posts ago, Spirit and Frontier are much less expensive today than they were a few months ago, and there are significant portions of both airlines network that wouldn't fit well in the JB system that could be redeployed rapidly to fill out JFK and/or LAX and/or EWR. Both airlines would also rapidly grow JB's Florida franchise and add incremental relevance out West.

All just one dudes opinion, worth exactly what you paid for it, maybe less.
