It's hard to say for certain since everything is covered by non-disclosure agreements until publicly announced. Anything anyone says is purely conjecture, including what I am about to say.

The -200 flying Skw does out of PHX is at a loss for them. The reason they are doing it is because it is less of a loss versus having those aircraft parked awaiting their lease expiration. The leases on those aircraft expire at the end of this year. I also understand the -900 flying has some tie to that.

So read between the lines there and who knows? There's a reason the training department is gearing up for a huge influx.
