I think it is purely the need for more airframes on a temporary basis.

We've seen a big increase in our DEN flying recently. It's nice to get away from IAD and ORD for a while. I was just through there yesterday.

We are staffed here at Mesa, so much so that they are offering 7-day, 30-day, 6-month and 12-month voluntary time off, and vacation buying (you can purchase hours of vacation and take them at your leisure). We've also furloughed 80, with 20 more coming.

I don't think anyone besides XJET has any airframes sitting around, and no one could buy new ones and staff them in time to cover the flying.
