The virus-ravaged airline industry reached a milestone Sunday, carrying more than 1 million passengers for the first time in seven months.

U.S. airport-security checkpoints processed 1,031,505 people, or 39.6% of the equivalent day in 2019, according to a tally by the Transportation Security Administration (TSA).

Several of the busiest days since mid-March have occurred in the past two weeks, and passenger loads have been gradually increasing, but that provides scant relief for an industry still reeling from the coronavirus pandemic. If Sunday’s level were maintained for an entire year, it would roughly roll the industry back to levels last seen 36 years ago, according to the trade group for large carriers, Airlines for America.

At Seattle-Tacoma International Airport, according to the latest reported data, the week of Oct. 4-10 brought a daily average of 18,600 travelers — the highest- level since mid-March, but just 34% of the year-ago level.

The steep drop in fliers has prompted billions of dollars of losses and tens of thousands of job cuts or voluntary furloughs as impacts reverberate across the aviation industry. A federal aid package that had covered the costs of airline payrolls and forbid job cuts expired Oct. 1 and attempts to extend it have faltered in partisan gridlock.

U.S. airlines rose, with a Standard & Poor’s index of major carriers advancing 1.8% at 9:59 a.m. in New York. United Airlines Holdings Inc. led the gains, climbing 3.5% to $35.35. United and Delta Air Lines Inc. said last week that they expect a long, slow recovery until there’s a vaccine.


Sunday was the busiest day for air travel since March 16, when 1.26 million people passed through domestic screening, according to the TSA.

At that time as the new coronavirus was first exploding in the United States, passengers were canceling flights en masse. Within weeks, the average number of fliers had fallen to less than 100,000 per day, a drop of 96% from 2019 numbers.

People have incrementally returned to the skies but in far fewer numbers than normal. The seven-day average as of Sunday was 871,513, or 35.6% of the equivalent week last year.

The overall passenger deficit since March is enormous. Airlines’ loads fell by more than 417 million passengers since the virus hit compared with the same period in 2019, a drop of about 75%, according to the TSA.
