Once you have cleared security, you either grab that much-awaited latte, or, if you are inside one of these cool airports, you head to the quirky, exciting, see-it-to-believe-it attractions that they boast of.
Jewel Changi Airport, Singapore
This newly-opened airport is not just a gateway but a destination in itself. It carries the legacy of Singapore as the &lsquocity in a garden&rsquo. With its Rain Vortex as the largest indoor waterfall in the world, the Forest Valley being home to almost 2,000 trees and 100,000 shrubs, this place sets a whole new benchmark for green airports.
Beijing Daxing International Airport
With its 180,000 sq m steel roof, it claims to house the world's largest airport terminal. Covering the area of 35 football grounds, the phoenix-shaped, golden-roofed airport is being built to lower the traffic at Beijing Capital International Airport.
Hartsfield&ndashJackson Atlanta International Airport, Atlanta
For 21 years in a row, it has been crowned the busiest airport in the world, but not many know that it is also considered the world&rsquos most efficient. In fact, the place offers non-stop service to more than 150 domestic and 70 international destinations, and provides about 63,000 jobs&mdashmaking it the largest employer of the state.
Tenzing-Hillary Lukla Airport, Nepal
Standing 2,845m above sea level in eastern Nepal, this airport has been ranked the world&rsquos most dangerous for the past 20 years. Serving as a gateway to the Everest region, it has perhaps the shortest runway in the world.
Adolfo-Suárez Madrid Barajas Airport
One of the largest airports in Europe also happens to be an architectural marvel. With its unique wave-shaped roof, supported by bamboo structures that allow natural light to brighten up the terminal, and collection of rainwater to provide for the beautiful landscape, it is also one of the most environment-friendly airports in the world.
