Reporting Notes
Data are compiled from monthly reports filed with BTS by commercial U.S. air carriers detailing operations, passenger traffic and freight traffic. This release includes data received by BTS from 77 U.S. carriers as of April 8 for U.S. carrier scheduled civilian operations.

See the BTS Airlines and Airports page for additional scheduled service numbers through January for U.S. airlines. International data by origin and destination is available through October. International totals in this press release consist of all U.S. carrier operations to and from the U.S. and from one foreign point to another foreign point. BTS' Airlines and Airports page does not include U.S. carriers' foreign point-to-point flights.

BTS has scheduled May 9 for the release of data through February.

None of the data are from samples. Measures of statistical significance do not apply to the complete air traffic data.

BTS separately releases preliminary enplanement estimates. Unlike the monthly air traffic releases, which are calculated from U.S. carrier scheduled civilian operations, the preliminary estimates are forecasted from data including all carriers and unscheduled service, with a total estimate of 81.1M passengers for January. Using only the U.S. carrier scheduled service figures, BTS' preliminary estimates for January were 71.1M passengers, which was over 99% accurate.
