In 2013, Delta Air Lines shuttled the most passengers of any other carrier in the world, while the busiest international air route was between Hong Kong and Taipei.
These are some of the findings published in the 58th edition of the World Air Transport Statistics, described as a 'yearbook' of the airline industry's annual performance.
The stats, published by the International Air Transport Association out of Montreal, also provide a snapshot of the industry nearly a century after the first commercial flight took off: 2014 marks the 100th anniversary of commercial aviation.
What started with a single aircraft, carrying a single passenger in 1914, is now a $2.4 trillion industry that carries more than 3 billion flyers and 48 million tons of cargo on nearly 100,000 flights a day.
In 2013, airlines in the Asia-Pacific region carried the largest number of passengers of any region, at 1.012 billion, followed by Europe (825.9 million) and North America (818.9 million).
Asia-Pacific also recorded the biggest increase percentage-wise, marking a 9.3 increase over 2012.
When it comes to regional breakdowns, in Africa, the country with the most passenger traffic (both domestic and international) in 2013 was South Africa. In Asia-Pacific, that title belonged to China. Elsewhere, Brits took to the skies the most in Europe last year, while Brazilians flew the most of all Latin America and Caribbean countries.
In the Middle East, that title belonged to the United Arab Emirates and in North America, Americans were the most traveled.
