It is possible to have a VFR-on-top or VFR clearance and be in the flight levels as the above rules have stated. But again, it is not allowed in Class A airspace. So where can I fly both VFR or VFR-on-top and be outside of Class A airspace? Hawaii.
§71.33 Class A airspace areas.
(a) That airspace of the United States, including that airspace overlying the waters within 12 nautical miles of the coast of the 48 contiguous States, from 18,000 feet MSL to and including FL600 excluding the states of Alaska and Hawaii.
