More than a million people passed through security at America’s airports once again on Monday.
The Transportation Security Administration (TSA) says it screened 1,080,346 people at airport checkpoints nationwide.
This sets the stage for another post-holiday uptick in coronavirus cases.
Roughly 18 million people have flown since the start of the holiday travel period on Dec. 18 and TSA numbers continue to average above one million passengers each day.
On Twitter, TSA spokesperson Lisa Farbstein said "if you choose to travel, please wear a mask."
On Monday, TSA said it expects air travel numbers to keep trending up in 2021, though not reach pre-pandemic levels.
