You should really ask a recruiter what the current terms are. Typical terms for the ATP/CTP class would be that if you leave within 12 months you would be required to pay back 6-7k. If you plan for that it’s not a bad deal, especially since there is always a possibility you might be stuck at a regional for a year if a recession happens. Plan for the worst, hope for the best. You might also see if the LCCs would be willing to get you current, although they are less likely to cover your ATP.
