As soon as a large jet takes off from an airport, the first thing pilots do is take the plane as high as possible, as fast as they can. Few people know that the average passenger airplane usually reaches its cruising altitude of 6 to 7 miles in the first 10 minutes of the flight. On the other hand, each airplane has its own optimum cruising altitude, which is based on its weight and some other characteristics.

The average cruising altitude of a commercial airplane is between 31,000 and 38,000 ft. At this altitude, the air becomes thinner. As a result, aircraft can travel more easily and, even more importantly, burn less fuel. So, can’t modern planes rise even higher than that? Or even fly to space?
