Just do it!!!
I went to Atlas after 10 years at some regional owned by Skypest, and it was the best decision I ever made!!! I had a blast in training, flew the coolest plane ever to some amazing destinations, and worked with some pretty cool people. I enjoyed being home for up to 13 days at once, and really had fun while traveling the world for 17 days (20 days once). For me being on the road that long was a cakewalk, maybe because I was in the Navy and had over 3 years floating at sea. Might not be as easy or enjoyable for everyone, specially the married family folk. As far as pay goes, it's not horrible compared to most regionals, although with all the $billion dollar signing bonuses it does make it hard to compete. Second year pay is not bad at $100/hr, although I didnt really get a chance to enjoy it much because I was hired somewhere else exactly on my one year anniversary. HUGE thanks to Atlas for helping me get to my dream job!
I really do miss the 747 and the awesome destinations :**(
