If it's some mom and pop operation and you make a gentleman's agreement to work for x amount of time to justify training costs, I understand about feeling bad. However, with regional airlines, you should not lose one second of sleep over of the prospect of getting your time and getting out. It's practically modus operandi at the regionals. They are used to, even expect pilots to leave at any time, including during initial training.

Think of it this way: They would not hesitate to furlough you if they needed to cut back and nobody in management would lose any sleep.

It's just business.

Anyway, what Dutch said. Apply anyway. You never know.
