More than 2 million people have passed through security checkpoints at U.S. airports over the last two days, according to statistics provided by the TSA. This is despite official guidance to stay home for the holidays as the coronavirus pandemic rages and the nation's death toll continues to rise. On both Friday and Saturday, about 1.07 million travelers passed through TSA checkpoints, the agency reported. That's down nearly 60% from last year, but still much higher than the typical checkpoint statistics since the pandemic began.
