In most areas of the United States, class E airspace extends from 1,200 feet (370 m) above ground level (AGL) up to but not including 18,000 feet (5,500 m) MSL, the lower limit of class A airspace.

Unless designated at a lower altitude, Class E airspace begins at 14,500 MSL over the United States, including that airspace overlying the waters within 12 NM of the coast of the 48 contiguous states and Alaska, up to but not including 18,000 feet MSL, and the airspace above FL 600.
As the federal authority over operations in all airspace and the regulating authority over operations, the FAA will ensure that the ETM cooperative vision aligns with agency goals and meets the requirements for safe and efficient operations.
The federal government has exclusive sovereignty of U.S. airspace. Congress delegated to the FAA the ability to define “navigable airspace” and the authority to regulate “navigable airspace” of aircraft by regulation or order.
Most commercial jetliners have a service (or certificated) ceiling of about 42,000 ft (12.8 km; 8.0 mi) and some business jets about 51,000 ft (15.5 km; 9.7 mi). Before its retirement, the Concorde supersonic transport (SST) routinely flew at 60,000 ft (18.3 km; 11.4 mi).
CEILING- The heights above the earth's surface of the lowest layer of clouds or obscuring phenomena that is reported as “broken,” “overcast,” or “obscuration,” and not classified as “thin” or “partial.”
At absolute ceiling, the aircraft can no longer accelerate, since any acceleration will lead to higher airspeed and therefore excess lift. Stated technically, it is the altitude where the maximum sustained (with no decreasing airspeed) rate of climb is zero.
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.
There are no specific regulations governing civil aircraft operations beyond the altitude of 60,000 feet. Nevertheless, certain exceptional aircraft like the Concorde and the Tupolev Tu-144 have managed to ascend to altitudes of FL600 (equivalent to 60,000 feet).
The busiest airport in the United States is Atlanta's Hartsfield-Jackson International Airport (ATL). The Atlanta airport is also the No. 1 busiest airport in the world. In 2022, 45.4 million passengers boarded commercial aircraft in Atlanta, according to the FAA.
What is the most expensive airspace in the world? Russia's airspace tariff is widely known for being one of the most expensive in the world. Jetex estimates that the Russian Federation assesses overflight charges ranging from $63.6 for aircraft up to 50 metric tons to $115.5 for aircraft over 400 metric tons.
