I'm looking to start PPL training soon, and the closest airfield is Austin-Bergstrom International, which is a class C. The only downside I see to doing training at KAUS is that the few PPL programs there has planes no smaller than 172's, which is 15% more costly than the alternative PA-38 at an airfield 30 miles north, or marginally cheaper 172's 30 miles south in San Marcos. Instructor rates are roughly equal. 150/2's don't seem to exist around here.
So the question is, are there advantages to training in a class C that make up for the cost difference? What disadvantages do you foresee?
