The Dallas-Fort Worth International Airport is now the busiest in the world, The Wall Street Journal reports (paywall):

"In May, DFW had 12,109 departing passenger flights, edging out Chengdu, China, by 86 flights for the title of busiest in the world, according to Cirium, a London-based travel data and analytics firm. In June, DFW widened its lead over Chengdu, Cirium says."

DFW had already become the nation's busiest airport in May.

Before the pandemic, DFW usually ranked behind several U.S. airports, according to the WSJ:

"DFW typically ranks behind Atlanta, Chicago O'Hare and Los Angeles in takeoffs and landings. But due to the instant transformation of the airline business, DFW finds itself at least temporarily on top, with long-lasting implications for travelers."

Busy, of course, is a relative term right now. "American will hit 667 flights a day later this month," the paper reports. "Last summer it flew more than 900 a day, and with larger airplanes."
