Customers will soon be able to book the first non-stop flight between the U.K. and Australia, set to become one of the world’s longest flights.

Qantas has confirmed that tickets for the record-breaking flight between London and Perth, which spans some 9,000 miles, will be on sale in April, although they have not yet set an exact date or revealed pricing.

The world's third-longest flight is expected to take around 17 hours, with the exact time dependent on variables like winds along the route. Qantas will service the 9,008-mile route with the Boeing 787-9 Dreamliner.

“This is a game-changing route flown by a game-changing aircraft,” Qantas CEO Alan Joyce said in a statement. “Australians have never had a direct link to Europe before, so the opportunities this opens up are huge.”

To make the very long journey more comfortable, Qantas recently introduced its new “Premium Economy” cabin seats, which have a pivot mechanism and are designed to cradle passengers.

“It’s almost like you're flying in Zero G,” Phil Capps, Qantas' head of customer product and service development, told Travel + Leisure.

The flights between London and Perth are set to take off in March 2018.

The current longest flight in the world is operated by Qatar Airways, from Doha to Auckland. That flight takes about 17 hours and 40 minutes, and covers 9,031 miles. Qatar just began operating the route last month.
