Hello 7Q, I'm in the same boat as you, I'm a captain at a South American airline with 5000 tt, got hired at a regional, every thing seemed ok, except the pay, I did my research before, but I have come to the repentance of going regional, I left after ground school, also got my old job back, and I will do everything possible to at least get into a LCC and move on from there, personally I do not recommend the regionals to anyone, if you have already flown bigger equipments and pay. Try for something at the same level not below.
