How many planes are in the air right now?
At a busy moment there are somewhere between 15,000 and 22,000 aircraft airborne worldwide, of which perhaps 10,000 to 13,000 are commercial passenger flights and the rest are cargo, business, military and general aviation. The number swings by a factor of two or more across the day, peaking around late morning European time when the Atlantic, European and Asian peaks overlap, and bottoming out in the small hours. Flightradar24 has tracked over 20,000 simultaneous flights on record days. Roughly 1.3 million people are in the air at any given moment.
How the figure is arrived at
Aircraft broadcast their position continuously by ADS-B; a global network of volunteer ground receivers picks these up and a tracking service counts the unique aircraft currently transmitting. Coverage is nearly complete over land and increasingly over ocean via satellite receivers, so the count is close to a census rather than an estimate.
