So I reached out to a few flight schools in my area. I got all kinds of quotes from $9,000 - $15,000 for my PPL training / cert etc. The wide range seems confusing. They all seem to cover materials, etc. Some of the books I could pick up myself on Amazon at a fraction of the quotes. The pricing seems quite varied, is this normal? going form 9K to 15K just seems.....interesting.
