They hire people from 121 /135 / military guys such . if you have more than 1500hrs , or being a captain at your previous job helps to upgrade fast . Retired 121? Yes they do . I’m not really sure what kind of qualifications they look when it comes to hiring , I believe it’s a mix bag of young and old with different levels of experience!! What they have is a bunch of happy high spirited men and women for sure .
