Qantas has been named outside the top 10 in the annual Skytrax world's best airline rankings, with a number of surprising entries besting Australia's national carrier.
The 'Flying Kangaroo' was rated 11th among the top 100 airlines, while Singapore Airlines was named the world's best commercial carrier at a ceremony on London on Tuesday.
The Skytrax rankings are based on a survey of 20.36 million travellers from more than 100 different countries, covering more than 335 different airlines.
It measured 49 parameters spanning from boarding procedures to quality of service to seat comfort.
Overall, Asian carriers dominated the top end of Skyrax's rankings – earning nine of the top 10 spots – while only one Australian airline broke into the top 20.
Singapore Airlines, Qatar Airways, ANA All Nippon Airways, Emirates, EVA Air, Cathay Pacific Airways, Lufthansa, Hainan Airlines, Garuda Indonesia and Thai Airways rounded out the top 10.
Outside of Qantas, Virgin Australia (22) and Jetstar Airways (46) also made the top 100.
Qantas earned top honours as the best airline within the Australian Pacific, while Jetstar won best low-cost airline in the region. Qantas also won the best airlines staff service in Australia.
Thai Airways was named the world's best economy class airline, while Japan Airlines earned the award for best economy class seats.
It's the first time since 2008 that Singapore Airlines has held the crown, beating last year's victor, Qatar Airways, which finished second.
"Singapore Airlines is honored to be named World's Best Airline in the Skytrax awards, and I dedicate it to the 26,000 SIA Group employees who focus every day on delivering the world's best travel experience to our customers," Singapore Airlines CEO Goh Choon Phong said in a statement.
Skytrax noted Singapore Airlines' premium offerings and its consistently best-in-class seating as a reason for its resurgence to top commercial carrier.
"We congratulate Singapore Airlines onbeing voted the World's Best Airline by customers for a fourth time in the awards history," Skytrax CEO Edward Plaisted said on Tuesday.
