Data note: Passenger totals represent scheduled enplaned revenue passengers on U.S. flights. PDEW is calculated as total arriving and departing passengers divided by two directions and 365 days. Carrier shares are based on BTS-reported scheduled enplaned revenue passengers. Freight and mail include scheduled and nonscheduled activity. Destination figures are BTS-reported passenger totals in thousands; route PDEW is calculated from the latest rolling 12-month passenger total. Historical charts retain each monthly BTS endpoint as future updates are generated.
