|The United States' Atlanta Hartsfield-Jackson International Airport (ATL) is the most efficient airport in the world, according to a report released Thursday.
The report was released by Air Transport Research Society, an aviation think-tank based in the University of British Columbia's Sauder School of Business.
The annual report compared the operational and management efficiency, as well as cost competitiveness of 183 airports and 25 airport groups in North America, Europe, Asia and Oceania.
It found that airports in Atlanta, Seoul, Copenhagen and Sydney were the leaders in their respective continents, among international airports serving more than 15 million passengers a year.
"Our report shows that the world's most efficient airports are supplementing core income with money generated through non-aeronautical revenue streams, such as parking, office rentals, retail activity and real estate development," said Professor Tae Oum, who led the study.
ATL generated 63 percent of its total revenue from non-aviation activities, compared to the lowest-ranked North American airport Denver International Airport, of which only 37 percent came from alternative sources.
In Asia, after five years on top, Hong Kong International Airport was bumped down to third place, after Gimpo International Airport and Incheon International Airport, both near Seoul, South Korea.
Among Canadian airports, Vancouver International Airport ranked highest, coming in fourth in North America, the report said.
