30,000 TO 35,OOO FEET ==Addendum== The above answer applies to modern commercial type jets. Smaller business jets can easily cruise in the 45,000 to 50,000 feet range. The Concord cruised at around 55,000 feet with a maximum cruise altitude of 60,000 feet. Military jets, of course, operate at various altitudes depending on design mission.
Boing 747's, popularly known as Jumbo Jets, typically cruise at around 32,000 to 38,000 feet altitude. This is between about 6 and 7 miles high.
At cruise speed, commercial jets typically fly at altitudes ranging from 30,000 to 40,000 feet (about 9,000 to 12,000 meters). This altitude allows for optimal fuel efficiency, reduced air resistance, and avoidance of weather disturbances. The specific altitude can vary based on factors such as flight route, aircraft type, and air traffic control regulations.
35,000ft (A380-800, initial cruise altitude). The service ceiling (maximum altitude) of this aircraft is 43,000 ft.

The average cruising altitude for passenger planes typically ranges from 30,000 to 40,000 feet (about 9,000 to 12,200 meters). Most commercial jets cruise at around 35,000 feet, where the air is thinner, allowing for better fuel efficiency and smoother flight. This altitude also helps to avoid weather disturbances and air traffic.
Usually Max Range and fuel consumption. If it is a short trip, the cruise altitude may be limited. Cruise altitude is determined by a number of factors, among which are winds, weather, length of flight, fuel economy, etc. Generally speaking, the higher a jet can fly, the more it will save in fuel. However, on shorter legs, an aircraft may not be able to reach the most economical operating altitude. Then, too, winds and weather can be major factors in selecting a lower than optimum cruise altitude.
No. High altitude winds are certainly strongest in the jets streams, but there is other wind.
This is too broad of a question. Different size jets will have different high cruise and long range cruise speeds. The link below is a good place to start, it shows the high cruise speed for a number of aircraft and even has graphs comparing the jet to others within a category.
At cruise altitude (35,000ft) the average cruise speed is 460 knots - 530mph.
depends on its speed, wind, and density altitude, and which jet you are asking about - at average cruise speed for large passenger jets at normal cruising flight levels its about 450 to 600 miles in an hour but due to wind and other factors can vary from this
