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 67 U.S. carriers as of Dec. 1 for U.S. carrier scheduled civilian operations.

BTS is withholding the scheduled release of estimated U.S. airlines’ traffic data for November and December because the estimates are statistical forecasts based on previous trends. The estimates do not account for the impact of the coronavirus.

See the BTS Airlines and Airports page for additional scheduled service numbers through September for U.S. airlines. International data by origin and destination is available through June.

BTS has scheduled Jan. 15 for the release of data through October.

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