Training and bonus contracts are apples and oranges.

I’m unaware of a regional that forces a new hire to sign a repayment contract as a condition of hiring. You show up, you get your training ... if you want to leave the day after you’re signed off IOE, you’re free to do so.

Bonus contracts are different. One doesn’t have to accept the bonus. If one does, then you either stay the agreed term or pay back the portion you’ve “shorted” the employer.
