Millions of Americans return to air travel as vaccines and spring break fever kick in

Thirteen months into a pandemic that brought air travel to a near standstill, Americans are starting to take to the skies in substantial numbers again.

The Transportation Security Administration (TSA) has screened record numbers of travelers at airports across the country during the roughly two-week period in March that marks many Americans' spring breaks. For 17 days in a row now, the TSA has screened more than 1 million people U.S. airports, marking a significant milestone for the industry.
