How Much Non-Stop A350 Flights To London Will Cost Qantas

This week, Qantas ordered A350-1000s for non-stop, ultra-long-haul (ULH) routes as part of the so-called Project Sunrise.

The four-class aircraft favors higher-yielding passengers – vital for such long routes – with six first seats, 52 in business, 40 in premium economy, and just 140 in economy.

It won’t be as premium-heavy as Singapore Airlines to Los Angeles, JFK, and Newark using smaller A350-900ULRs. The type has just 161 seats – only business and premium economy, and no economy.


One route to see Qantas‘A350s will be Sydney to London Heathrow, 10,573 miles (17,016km) apart. It’s so long that it’ll be 11% farther than the current world’s longest, Singapore to JFK. It’ll have a block time to London of about 20h 30m.

This image shows the A350-1000’s theoretical range of 8,600 nautical miles. The real-world range will probably be 10-15% lower than that. Sydney-Heathrow is 9,188nm, so longer, and that’s based on flying through Russian airspace. It also helps to explain Qantas’ pretty low-density aircraft, increasing range and revenue performance.

What will it cost to operate?

Thanks to data provided by experts RDC Aviationwe have an idea of ​​how much the ULH route to London will cost to operate. Not to make a profit but to breakeven, based on a 90% overall seat load factor. Qantas would need more revenue than the numbers shown to make a profit.

One roundtrip will cost approximately US $ 560,0000 – over half a million – to provide, while a 1x daily year-round service will gobble up an estimated $ 204 million. That’s a fifth of a billion dollars just for one daily roundtrip on one route.

RDC shows that the breakeven cost is around $ 1,307 one-way at a passenger level, based on 90% breakeven. It would need to generate $ 1,307 on average from each of the 214 passengers across cabins. On top will be government taxes, a large and increasing amount, and potentially a fuel surcharge and any other fees.

Fuel will be over 50% of the cost

The above numbers are just the costs, over half of which is from fuel, which is sky-high now and reflected in the above numbers.

That fuel makes up such a high amount is no surprise: fuel becomes a disproportionately larger proportion of expenses on long-haul routes. They’re much more exposed to fluctuations in the price of jet fuel, none more so than this soon-to-be world’s longest route.

If the fuel price is even higher in 2025, the numbers above will go up. And if lower …

What’s the current quickest option?

Depending on demand specifics, a subset of a market may be willing to pay more for a faster, easier, and more convenient experience. And it can be monetized, as demonstrated by Qantas, with a quicker overall journey and no need to transit en route. At a 90% seat factor, it’d need 156,000 roundtrip passengers a year.

Based on Monday, May 9th, Google Flights shows the quickest journey time from Sydney to Heathrow is with Singapore Airlines. At 22h 40m, it includes a potentially worryingly short 50-minute connection in Changi. It is 50 minutes faster than Qantas’ existing same-plane Sydney-Darwin-Heathrow service.

It’d be about two hours longer than Qantas’ non-stop offering. You’d leave Australia at 18:00, arrive in Singapore at 00:20 the following day, leave at 01:10, and arrive at Heathrow at 07:45.
