DUBAI, United Arab Emirates (AP) — The city with the world's tallest building can now boast that it's home to the world's busiest airport for international passengers too. Dubai Airports CEO Paul Griffiths predicts Dubai International will handle a record 79 million passengers this year as it offers "more flights connecting more people to more destinations." The airport has been climbing the international aviation traffic rankings for years as it added capacity to accommodate the growing numbers of big wide-body planes like the Boeing 777 and Airbus A380 that Emirates favors.
