International travel roared back last year, pushing airports from London to Tokyo up in a global ranking of passenger traffic.

Dubai International Airport ranked as the second busiest in 2023, up from fifth place in 2022 and fourth place in 2019, according to Airports Council International's preliminary ranking, which was released on Monday. Passenger traffic to Tokyo Haneda International Airport jumped 55% last year from 2022, and the airport ranked fifth, up from 16th place a year earlier.

Global airports served 8.5 billion passengers last year, up 27% from 2022 but still about 6% below pre-pandemic counts, ACI said, citing preliminary figures.

The resurgence of international travel has been a bright spot for airlines with big international networks, while ultra-low-cost, domestic-focused U.S. airlines have struggled in recent months.

Nearly 78 million people used Denver International Airport last year, up 12% from 2022, but the airport, a major hub of United Airlines, fell in ACI's ranking to sixth place from third.

Hartsfield-Jackson Atlanta International Airport, Delta Air Lines' biggest hub, once again topped the list of the busiest airports, serving 104.7 million passengers, ACI said.
