How many people travel by air per day in u.s?

Answer 1

In the year 2010 there were 631,939,829 total passengers that boarded flights according to the Bureau of Transportation Statistics. The average number of people that fly per day in the United States is around 1.73 million.

Answer 2

The National Air Traffic Controllers Association says that there are, on average, between 25,000 and 30,000 passenger flights in the US per day. (http://www.natca.org/mediacenter/bythenumbers.msp) Let's estimate conservatively and pick 25,000 as our number.

Estimate that each airplane on average has 20 rows of people. (Yeah, some planes are much, much bigger, but the majority of planes are small.) Further guess that each row can hold 5 people on average. Then make a guess that on average a flight is 75% full, you get:

25,000 * 20 * 5 * 0.75 = 1,500,000 people per day

During burst periods (like Thanksgiving) the news is filled with reports that the airline expect to well exceed 2 million people each day, so 1.5 million on a normal day is probably not too bad a guess.
