Australia's national carrier Qantas Airways announced on Sunday (Dec 11) it will roll out non-stop 17-hour flights from Perth to London in March 2018.
The 14,498km-route flights are its first regular passenger flights directly linking Australia and Europe and are said to be "game-changing".
According to the Wall Street Journal, non-stop service to Europe, a previously untapped market, could increase growth for Australia, which is experiencing a tourism boom driven largely by visitors from China.
Future developments aside, there are several other non-stop flights which are currently in operation around the world.
Here are five of the longest non-stop flights by commercial airlines.
1. United Airlines' non-stop flights between San Francisco, United States, and Singapore

United Airlines' non-stop flights began operations just two weeks before SIA announced its plans for non-stop flights between the two cities.
The Boeing 787-9 Dreamliner features large glass windows, which are 65 per cent larger than any other fitted to a passenger plane. These windows are made of smart glass and can be dimmed electronically.
According to UA's website United Hub, cabin crew will also be able to control cabin lights to make them resemble different environments, such as a warm sunny day or a cool night sky.
