Factual Questions

Howyadoin,

Again, my googling skills are not equal to the task… so I submit to the TM:

Can anyone tell me roughly the number of commercial flights per day worldwide?

Thanks as always!!

This deserves an answer, but I couldn’t find a worldwide figure. According to this site, as of 1997 there were about 22,000 per day in the U.S. alone. He cites the U.S. Census Bureau. I don’t know if that counts international flights that begin or end in the U.S., or only domestic flights. Other sites mention various other figures, but without giving any source.

If you can find a figure for what proportion of flights are inside the U.S., you can get a ballpark estimate of the worldwide figure.
