Do you have a very good contact at FDX (like a relative)? If so, you can probably get called with whatever their published mins are.

If you don't know anyone, you will probably need turbojet PIC, lots of it, and maybe heavy over-water time to get called off the street.

Ask around and be very realistic about what you need to get to where you want to go. Mesa appears at risk of losing Go! and maybe a codeshare or two...you may want to beat the rush so you have your pick of jobs before the market is flooded with furloughed mesans.
