I think you are right but this looks like price gouging to me.Since those canceled by the Conquest closure are going to be scrambling for almost anything available, I suspect normal last minute pricing has been raised to maximize income from those travelers.

This isn't a matter of higher demand as in a high season like March break or Christmas.
The flight capacity has not changed.
The number of available seats has gone up and people have to re-book those same seats for way higher prices.
