Air travel has now dropped in the US each of the last five weeks.

The Transportation Security Administration is now screening about 4% of the number of people it did this time last year.

On Sunday, its officers screened 90,510 people, compared to more than 2.4 million on the same day in 2019. That’s a 96% drop from last year’s traffic.

Those numbers have fallen week-by-week. TSA began March screening just above last year’s travelers, but on the last day of the month, the agency screened about 6% of the equivalent day in 2019.

The steepest drop-off came in the third week of March, when traffic dropped from 61% to just 18% of last year’s traffic.

There are now 52% fewer international flights and 86% fewer domestic flights taking off weekly, according to Airlines for America, an industry group.

Overall, airlines are flying 71% fewer seats than one year ago, it said. Airlines have parked more than 1,900 planes since the pandemic hit the United States.
