WASHINGTON (AP) — Commercial air travel appears to be on the upswing despite the coronavirus pandemic. The U.S. Transportation Security Administration says its agents screened more than 1.3 million passengers at airport security checkpoints nationwide on Friday. Spokesperson Lisa Farbstein says in a tweet that the last time the number was that high was March 15 of last year, just days after the pandemic was declared. Public health officials generally have cautioned against commercial travel since then.
