I have been flying in, over, under, and through this class bravo for several years. My experience is Approach and/or Tower will give you the key to the city if they have the time for it. This is true despite the fact that ATL is the busiest airport in the world. It has triple Cat III ILS's working overtime some days. General aviation is not unwelcome, and commercial GA airplanes use 8/26 all day every day. Recreational and even student pilots are welcome after business hours as long as they realize they are in a significant airspace.
