My experience
I got on with Endeavor after being on the sidelines driving a semi for almost five years. I went to the local airport and flew around in a 172 for 6 hours, got a BFR/IPC signoff from an instructor and interviewed in December. I have 4000 hours total time, 3 Jet type ratings, and 5 years of 121 flying before my flying break though, so that may have made a difference. 24 days till I start class!!
