Air travel reached a new pandemic high point this past weekend, surging to as much as 24% of usual traveler volumes.
Transportation Security Administration (TSA) figures show about 2.3 million people passed through airport security checkpoints between Thursday and Sunday, down from the 10.4 million people the agency screened on the same days last year.
The busiest day was Sunday, when TSA screened nearly 634,000.
Sunday was American Airlines' second busiest day in terms of passengers since March, when air traffic was cratering. The airline has been capping flight capacity but recently announced that starting Wednesday it will allow every seat on each flight to be purchased.
Experts predict a surge of travel over the upcoming July 4 holiday weekend.
