Skytrax released its annual list of the best airports in the world at the Passenger Terminal Expo in Stockholm, Sweden.

Singapore's Changi International Airport took the top spot for the sixth year in a row.

Airports from Asia swept the top five spots.

No US airport placed in the top 25.

The consumer-aviation website Skytrax held its annual World Airport Awards ceremony in March at the Passenger Terminal Expo in Stockholm, Sweden.

For the sixth consecutive year, Singapore Changi International Airport took home the crown as the world's best airport. The facility is one of Southeast Asia's largest transit hubs and is a major cog in the city-state's bustling economy.

Changi Airport is world-renowned for its beautiful architecture, efficient operation, luxurious amenities, and plentiful dining and shopping options.

Airports from Asia dominated the top of the Skytrax rankings, sweeping the first five spots. European airports also performed well, with four in the top 10. Only one North American airport made it into the top 15. No US Airports made it into the top 25 with Denver International being the highest-ranked at 29.

Africa and South America were also not represented in the top 15. Cape Town International in South Africa is the highest ranked African airport at 21. South America's first representative doesn't show up until Bogota, Colombia's El Dorado International Airport at 46 followed closely by Mariscal Sucre International Airport in Quito, Ecuador at 47.

The Skytrax annual rankings are based on the impressions of nearly 14 million flyers from over 100 countries. More than 550 airports were included in the survey, which covers 39 service and performance parameters, including facility comfort, the location of bathrooms, and the language skills of the airport staff.

Here's a closer look at the other airports that made it to the top of the prestigious Skytrax list:
