New statistics on air travel reveal that Americans made up the largest group of air travelers in 2017, with nearly 19% of global passenger traffic coming from the United States.
The latest report from the Montreal-based International Air Transport Association show that air passenger numbers exceeded four billion for the first time last year, marking a 7% increase over 2016 or an additional 280 million trips by air.
Report authors attribute an improvement in global economic conditions and lower average airfares for the spike.
Analysts also broke down passenger traffic by nationality for both international and domestic travel.
The U.S. tops the list with 632 million passengers taking to the skies in 2017, representing 19% of global flyers, followed by China (555 million), India (161.5 million), the United Kingdom (147 million) and Germany (114 million).
Regionally, the results remain unchanged: airlines in the Asia-Pacific region carried the largest number of passengers in 2017, taking up 36% of the global market share with 1.5 billion passengers.
That figure also represents an 11% increase over 2016.
After Asia-Pacific, Europe and North America were the top markets.
When it comes to the top five airlines by total number of passenger kilometers flown, U.S. carriers dominate the ranking with American Airlines (324 million) leading the charts, followed by Delta Air Lines, United Airlines, Emirates Airline and Southwest Airlines.
And the busiest international air routes for 2017 were once again air corridors in the Asia-Pacific region, led by Hong Kong and Taipei Taoyuan, followed by Jakarta Soekarno-Hatta and Singapore and Bangkok Suvarnabhumi and Hong Kong.
