Qantas has dated the 20-hour flight, and here is who should actually book it

Qantas has put dates on the flight it has been promising for a decade. Daily non-stop services between Sydney and London begin in October 2027, with tickets on sale from February 2027, and the Sydney to New York route follows shortly after. Both will be flown by a version of the Airbus A350-1000 built for the job, with 238 seats where a normal A350 carries far more, and both will run to about 20 hours in the air. That would make them the longest scheduled flights in the world.

What was announced, and when

Qantas confirmed the plan at Airbus in Toulouse on 18 June 2026, when it showed the first of its 12 ultra-long-range A350-1000s. Chief executive Vanessa Hudson said "the tyranny of distance for Australians has finally been conquered". The first aircraft, named Vega, is due for delivery in April 2027, after test flights in July that covered about 19 hours from Toulouse to Melbourne and more than 24 hours on the way back. London is the first route because it is the one Australians have asked for since the Kangaroo Route began, and New York, which Qantas has flown non-stop once, as a research flight in 2019, comes next.

Inside a plane built for 20 hours

The seat count is the tell. A standard A350-1000 can carry more than 400 people; Qantas has fitted this one with 238: six first-class suites, 52 business suites, 40 premium economy seats at a 40-inch pitch and 140 economy seats at 33 inches. Fewer seats means less weight, which is what makes the range possible, and it means the economy cabin has more room per person than on most long-haul aircraft. Qantas spent years working with sleep researchers on the cabin, including a wellbeing zone where passengers can stand and stretch, and lighting and meal timing set to the destination's clock rather than the departure's.

What 20 hours in a seat actually means

The current record holder is Singapore Airlines' New York to Singapore, at a little under 19 hours. Sydney to London adds roughly an hour to that; Sydney to New York, depending on winds, sits in the same range. For a passenger the arithmetic is two full meals, a night's sleep, a film and a morning, without a stop in Singapore, Doha or Los Angeles. The reason to do it is not the hour saved in the air. It is the three to four hours saved on the ground at a hub, the second security queue, and the risk of a missed connection when the first leg runs late.

Who this is for, and who should keep the stopover

It is for the traveller who values the hours and can afford the fare, which Qantas has not published and which the seat count says will not be cheap. Business travellers and anyone who has lost a connection at Doha will pay it. Families with young children, anyone who struggles to sleep sitting up, and anyone on a budget will still find the one-stop routes cheaper and, honestly, easier: a stretch and a shower in Singapore breaks a 24-hour journey in half. For Australians heading to the Himalaya, nothing changes: Kathmandu is reached via Singapore, Bangkok or the Gulf, and the flight is short enough that a stop is a relief, not a cost.

If the appeal of the flight is the idea of arriving somewhere remote in one go, the Everest Base Camp trek begins with a 30-minute flight to Lukla that is, in its own way, more memorable than 20 hours to London.
