For the fourth consecutive day after the Christmas holiday, more than 1 million people passed through airport security checkpoints on Tuesday, according to the Transportation Security Administration.
It is also the eighth of the last 12 days where checkpoint traffic exceeded 1 million people.
Sunday was the single busiest day of the pandemic at airports, with nearly 1.3 million people screened.
Tuesday’s tally was at least 1,019,347 people, the agency said.
The numbers represent a spike in pandemic era travel and raise public health concerns.
