Qantas on Saturday launched the first non-stop passenger service linking Australia and Europe, with a Boeing 787 Dreamliner departing Perth for London on one of the longest flights in the world.
Here are some of the world's longest flights:
Auckland to Doha - 17 hr 40 min
Auckland to Dubai - 17 hr 20 min
Auckland is also the origin of Emirates Airline Flight 449, with Airbus A380 superjumbos travelling 14,200 km in 17 and a half hours to Dubai.
Perth to London - 17 hr 20 min
The new Qantas service is the first regular link between Australia and Europe, with the airline's Boeing 787 planes connecting Perth and London in just over 17 hours. The 14,500-km route is part of the airline's ambitious plans to eventually connect Europe with airports on Australia's eastern seaboard as new, more efficient aircraft become available.
Los Angeles to Singapore - 17 hr 20 min
United Airlines launched its service connecting Los Angeles' LAX airport to Singapore using 787s last year, saying the 14,100-km link would be the longest non-stop flight -- in terms of distance -- from the United States to anywhere in the world.
Houston to Sydney - 17 hr 30 min
United's 787s also connect Houston in the southern US to Australia, crossing 13,800 km in around 17 and a half hours.
Singapore to New York - 19 hr
The longest flights operating today pale in comparison with Singapore Airlines Flight 22. The carrier flew Airbus A340 airliners from the city- state to New York's Newark airport -- a journey of over 15,000 kilometres -- from 2004 to 2013, when the service was suspended to cut costs. But the airline plans to restart flights on the route, using the ultra-long range version of the Airbus A350.
