Source? Is this the number of passengers, aircraft movements, or something else? Also is it for American citizens or just people flying from US to non-US?

Also factor in that many people who do fly, fly multiple times a year.

If that 93m is individual passengers then you should discount it quite a bit to accommodate frequent fliers and overseas tourists returning home.

A google search snippet :) thats number of trips taken by US citizens Number of US citizens who traveled is 44 mil so about half of the number of trips.
