May 2020 U.S. Airline Traffic Data

Thursday, August 13, 2020
Date: Thursday, August 13, 2020


U.S. airlines carried 8.4 million systemwide (domestic and international) scheduled service passengers in May 2020, unadjusted, according to the Bureau of Transportation Statistics’ (BTS), down 89.6% from May 2019.


The Bureau of Transportation Statistics (BTS) is withholding the scheduled release of estimated U.S. airlines’ traffic data for June and July because the estimates are statistical forecasts based on previous trends. The estimates do not account for the impact of the coronavirus. BTS additionally is withholding the seasonally-adjusted numbers due to the unprecedented decline in air traffic.


BTS reported 8.2 million domestic passengers and 0.2 million international passengers on U.S. airlines flights in May.


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 1-12) and complete data since 2000.
