Air travel on the weekend of the 4th of July increased to new high levels of pandemic.
The Transportation Safety Authority (TSA) said it was examining more than 700,000 people every three days this weekend – for the first time since more than 700,000 since mid-March.
Nearly 2.7 million people screened during the four-day period from Thursday to Sunday were about 28% of the 9.4 million people observed over the same weekend last year.
The agency has also reported more than 960 corona cases in its workforce, including six deaths.
The weekend was the first since April, when American Airlines began selling full-capacity flights.
United Airlines has also sold capacity flights. Both airlines say they are warning passengers that flights could be complete and will allow passengers to book free of charge for a less full flight.
The American said on Saturday that the three busiest days of the pandemic were the first three days of July.
While airlines note that the volume of travel is still much lower than sustainable levels, they are preparing for growth from low levels in mid-April.
Data from Airlines for America, which represents major U.S. carriers, shows that airlines have removed 800 aircraft that have been stored during the pandemic since Sunday. Thirty-nine percent of the U.S. fleet has landed now, according to the team.
U.S. airlines operate only 46% of their normal capacity, according to the group.
