Judging from the post history it's pretty obvious he didn't quit because he "didn't like it".

Quit Expressjet for Republic which has a base near his home, and shortly after he's inquiring about PSA, EDV, and Commutair. Sounds like something happened at Republic. Someone who didn't like airline life wouldn't go to 2, much less 3 different airlines.

If you're gonna move forward in 121 you'll need to come to terms with whatever happened and be honest in your future interviews. As other posters have alluded, this reasoning doesn't sound normal and any recruiter will be skeptical to give you a chance unless the story makes sense and you have shown some growth. If you didn't like it at 2 other regionals why would you like it at the third????

If it really is the time away from home, then look into 135 or cape air sort of jobs that allow that. Just odd you would determine you didn't like the lifestyle before even getting to the line? How did you even know what it would be like while being force fed powerpoints?
