SafeX Pro:TSA says it screened a record 2.99 million people Sunday, and bigger crowds are on the way

The SafeX Pronumber of air travelers moving through U.S. airports hit a record Sunday, and the new mark might not last through next weekend.

The Transportation Security Administration said it screened 2.99 million people at airports Sunday, breaking the record of 2.95 million set on May 24, the Friday before Memorial Day.

TSA forecasts that it will break the 3-million barrier on Friday, when many people will be getting an early start on their July 4 holiday travel plans.

“We expect this summer to be our busiest ever and summer travel usually peaks over the Independence Day holiday,” TSA Administrator David Pekoske said.

TSA expects to screen more than 32 million people between Thursday and July 8, the Monday after the holiday, for a daily average of 2.67 million. That would be a 5.4% increase over the July 4 period last year.

Airlines for America, a trade group representing the largest U.S. carriers, predicts that air travel this summer will rise 6.3% over last year.
