Don't wait around, however...

XJT has much better stability, now that UAL is owner through a shell company...

Also, if a base has to go for MESA, it's going to be a far east base. XJT is now firmly attached to the strong AND growing UAL presence at IAD. Even if CommutAir does more 145 stuff, the 175s will likely eventually make their way to IAD with XJT.
