RANKED: The 20 best airlines in the world

Qatar Airways has been named the best airline in the world for 2017 by the leading consumer-aviation website Skytrax.

The Doha, Qatar-based airline was presented with the award on Tuesday at a ceremony during the 2017 Paris Air Show.

This is the fourth time Qatar has garnered this honor with wins in 2011, 2012, and 2015.

In a statement, Qatar Airways Group CEO Akbar Al Baker wrote:

"For Qatar Airways to be named the World's Best Airline particularly at this critical point in time, is a significant testimony of our passengers' belief and trust in our unwavering commitment to deliver only the best. This award is also a reflection of the hard work and dedication of every employee at Qatar Airways. Our recognition at Skytrax this year is especially important as these awards are voted by travelers. To them, I offer my sincere thanks, and I look forward to welcoming them on board soon."

Overall, airlines from Asia dominate the elite end of Skytrax's rankings - taking nine of the top 10 spots. At the same time, no US airline cracked the top 30. Delta got the closest to the top with a 32nd place finish.

The Skytrax rankings are based on the impressions of 19.87 million travelers from 105 different countries. The survey, which covered more than 325 airlines, measured 49 parameters ranging from boarding procedures to seat comfort to the quality of service.
