Which is the world’s busiest international airport? In 2014, it was Dubai International Airport in United Arab Emirates. An estimated 70.5 million international passengers went through the airport. The runner up was London’s Heathrow Airport (United Kingdom) with 68.1 million passengers. While you are waiting for your flight at the Dubai Airport, you can go for a swim, walk through a Zen garden, and even rent a small cube-like room to take a nap in.
