Just like many other pilots your experience is in the realm of what is needed to be hired by a major, so I guess its just a waiting game before getting the call.

It's a tough decision- living in base vs. 121 jet time. I think either way you are going to get the call pretty soon from someone assuming your apps are out.

Do you have family? Would you be moving them now and again when the major calls? Would that be a factor or would you be trying to commute to FLL from Houston (or elsewhere)?

Did you get the big signing bonus from Silver? Any obligations there?

Sounds like you'll get a signing bonus from Mesa which would probably just cover moving expenses after taxes.

I'm like 51% stay at Silver to get some 121 PIC time sooner as I think that is lacking if I understand your posted hours correctly.
