I researched several online schools and actually found that ERAU (worldwide) was the cheapest. Of course, none are cheap. ERAU did give me credit for my dispatch and Pilot certifications. If I remember correctly it was around 30 hours. They do give more if you have you ATP. I already have a nursing degree and they did transfer most core classes. If you go this route pick a community college and take the core classes there. ERAU has a transfer guide that will tell you what class will transfer to fulfill the requirement there. ERAU will not let you dual enroll so save yourself some cash and take everything that you can at the community college!
