Even after the pandemic travel slowdown, Atlanta's airport was busiest in the U.S. in 2020

ATLANTA — Hartsfield-Jackson International saw steep drops in traffic in 2020, but with air travel everywhere taking a hit from the COVID-19 pandemic, it still handled more passengers than any other U.S. airport.

The Atlanta airport had 20.6 million passengers boarding flights in 2020 — a 62% decline from a year earlier, according to figures from the U.S. Department of Transportation.

The traffic put Hartsfield-Jackson ahead of Dallas-Fort Worth in second place, Denver in third place, Chicago O'Hare in fourth and Los Angeles International in fifth.

Minneapolis-St. Paul International Airport wasn't in the top 10 U.S. airports in 2020 traffic data released by the DOT. The airport's operator previously disclosed that passenger traffic, as measured by those boarding flights and getting off them, was down 62.5% last year.

Atlanta's airport has held the No. 1 ranking in the world for passenger traffic since 1998, but 2020 global rankings have not yet been released.

Hartsfield-Jackson also handled more flights than O'Hare last year, according to Federal Aviation Administration figures, after O'Hare held the title for the most flights in the world in 2018 and 2019.

At the lowest point in April, Hartsfield-Jackson had only 450 flights a day and about 9,000 passengers, down from 2,600 flights a day and 310,000 passengers in pre-pandemic times, outgoing general manager John Selden said Thursday at the South Metro Development Outlook virtual conference.

"We look forward to very good passenger traffic coming through spring break and then into summer," he added.

DFW saw a 48% decline in traffic last year, a smaller drop than some other hubs, bringing it ahead of Los Angeles with its 67% decline and O'Hare with a 64% decline. Denver had a 52% decline in passenger counts and jumped from the No. 5 spot to No. 3.

Some inland hubs like Dallas and Denver saw smaller declines in traffic because of their focus on connecting domestic passengers across the country, while the pandemic hit overseas flights and international hubs the hardest because of international travel restrictions to limit the spread of the coronavirus.

New York's John F. Kennedy International Airport is the busiest U.S. airport for international traffic and saw a 76% decline in passenger counts in 2020.

While Atlanta in normal times has a decent share of international flights to Latin America and Europe, it is not as dependent on international flights as JFK and other coastal hubs like Newark, Los Angeles and San Francisco.
