It is almost impossible to know how many planes take off and land every day worldwide. There is an average of 23,000 scheduled take-offs and landings in the United States everyday. That number does not include private planes, chartered jets and other non-commercial aircraft.
The 23,000 scheduled take-offs and landings in the United States does not mean that there are 23,000 individual planes in the sky. A single plane can take off and land multiple times per day, meaning that there is typically a limited number of planes in the U. S. completing these take-offs and landings. It is estimated that the 23,000 take-offs and landings in the U. S. require approximately one quarter of that number of planes.
