The Bureau of Transportation Statistics (BTS) is withholding the scheduled release of estimated U.S. airlines’ traffic data for January and February because the estimates are statistical forecasts based on previous trends. The estimates do not account for the impact of the coronavirus.

U.S. airline traffic reports are filed monthly with BTS. See the tables that accompany this release on the BTS website for summary data since 2016 (Tables 1-24) and complete data since 2000.
