I used to work at FAPA in the early 90's and I might have even sold some of ya'll the memberships back then. FAPA was a good company to work at for a struggling CFI looking to supplement his income with a good paying part-time job. The owners of FAPA and Air Inc. used to be partners but split due to the different directions they wanted to take FAPA.
Kit started Air Inc. out of his home and put most of the information into a photo copied 3 ring binder that was mailed out. Nothing fancy. FAPA, on the other hand, continued to provide expensive, glossy publications, had a large staff and nice offices in Atlanta.
In the early 90's with many majors furloughing, FAPA had an unsustainable business model with high overhead costs. The Information Age had arrived and it became nearly impossible to compete with the free flow of airline employment gouge on the Internet.
Clearly, Kit did not learn from FAPA's mistakes. It purchased many of FAPA's assets and ideas (glossy magazines, pubs, hotlines, office facilities, etc.) instead of sticking to low the low cost model that that made Air Inc a modest success.
FAPA's owner told me years later that the Internet was like "piranha constantly nibbling at your boat and if you were to survive, you needed to keep building a stronger boat". I suppose Kit started construction of the boat too late.
Can most of the information that Air Inc provides be obtained from other sources? Of course it can, but not without considerable time and effort. Its the collection of that information in a one-stop-shop that you paid for. You do the same thing if you subscribe to Aviation Daily. Air Inc's $135/yr was a bargain by that measure in my humble opinion.
