Keep in mind the majority have been captains at Spirit. It's still competitive, so if you go to a ULCC I would recommend having at least 1000TPIC from your respective regional.

FWIW. Turned down a job at Spirit because I never really wanted to work there. Held tight at my previous employer and took on additional responsibilities, got a call from Southwest 9 months later. I think you're better off staying put as long as you can get PIC time and check airmen or some other additional duties.
