NEW YORK (WABC) — Experts say this holiday weekend could be the busiest for air travel since the pandemic began.More than 1.58 million people passed through TSA checkpoints on Friday. That’s the most people to fly in a single day since the pandemic began.

It came on the same day the CDC announced fully-vaccinated Americans can travel at “low risk to themselves.”

However, the organization still asks people not to travel, unless they have to.
