More than 3 million people passed through U.S. airport security on Sunday, the first time that number of passengers have been screened in a single day as travel surges, according to the U.S. Transportation Security Administration.

The record, which was widely predicted to happen at some point over the July Four holiday weekend, topped the June 23 mark of more than 2.99 million screened passengers. Eight of the 10 busiest days in TSA’s history have come this year as the number of travelers tops pre-pandemic levels.
