Dubai International Airport saw a surge in passengers over the first half of 2022 as pandemic restrictions eased and the upcoming FIFA World Cup in Qatar will further boost traffic to the city-state's second airfield, its chief executive said Wednesday. Paul Griffiths, who oversees the world's busiest airport for international travel, told The Associated Press that the airport handled 160% more traffic over the past six months compared to the same period last year, part of an air travel rebound around the world.
