I’ve heard that Aviator does have some issues meeting timeline goals. They have really changed their business model over the years.
If a zero to hero program is what you are looking for I would highly recommend Blue Line Aviation in NC. They do have a little pricey program but they fly new equipment, meet timelines, and usually hire their graduates. I think they have self examination authority fro Private and Instrument along with 2-3 DPEs that pretty much work exclusively for them.
