All airspace above FL 600 is Class E airspace. Uncontrolled airspace or Class G airspace is the portion of the airspace that has not been designated as Class A, B, C, D, or E. It is therefore designated uncontrolled airspace. Class G airspace extends from the surface to the base of the overlying Class E airspace.
Class A airspace generally begins from 18,000 feet mean sea level up to and including 60,000 feet. Operations in Class A are generally conducted under Instrument Flight Rules and primarily used by higher performance aircraft, airline and cargo operators, etc.
The Lockheed SR-71 Blackbird had a service ceiling of FL850 and routinely operated above FL600. Many other aircraft in this category (e.g. MiG-25, Tsybin RSR, U-2, RB-57F, M-17 and M-55) can also fly above FL600.

In short, the real purpose of Class F is to allow flights to remain IFR in uncontrolled environments. Since this is a sort of mix between Class E and Class G airspace, there is no Class F inside the United States.
Class A airspace is generally the airspace from 18,000 feet (~3.4 miles, 5.5 km) mean sea level (MSL) up to and including flight level (FL) 600 (~11.4 miles, 18.3 km), including the airspace overlying the waters within 12 nautical miles (NM) (~13.8 miles, 22.2 km) of the coast of the 48 contiguous states and Alaska.
In the United States, there are no specific provisions for aircraft operations above 60,000 feet for civil aircraft, and most existing applications are limited to military operations.
A: No commercial or business airplane flying today can exceed 100,000 feet. Special rocket-powered airplanes can fly over 100,000 feet to gather data, but they are specially designed for it.
Can you fly at 80000 feet? The US Air Force U-2 reconnaissance aircraft flies at 72 000 feet almost every day for many hours. The world's fastest manned aircraft, the SR-71, flew for many years at 80 000 feet and higher.
