Hello ! I’ve been reading the requirements for some regional airlines, and of course all of them require ATP certificate, once I have the whole licenses that atp flight school provide, do I have to do something else to get the ATP ? Or just the 1500 hr after getting comercial???
You will need to get to 1,500 hours and pass the ATP written exam. As part of your new hire training at the regional you will take your ATP checkride in the simulators there.
