The Economics of a 22-Hour Flight: Testing Qantas's Project Sunrise Math

DALLAS — A Project Sunrise departure from Sydney (SYD) to London-Heathrow (LHR) will leave with 238 seats to sell and, by Airways' tally of Airbus figures, room for about 50,000 US gal (189,200l) of jet fuel. At US$194.90 a barrel, the global average in the International Air Transport Association's latest weekly jet fuel reading as of September 26, 2026, a full load is worth roughly US$232,000 before hedging and into-plane charges, by Airways' calculation. That is about AU$330,000 at the Reserve Bank of Australia's September 25 exchange rate. Airbus says Qantas Airways (QF) intends a flight time of 21 hours and 40 minutes for its Project Sunrise routes.

Qantas plans to start nonstop Sydney–London service in October 2027, alongside its existing one-stop service via Singapore, and Sydney–New York service in mid-2028. Both depend on regulatory approvals and aircraft certification. Qantas's June 2026 investment case names JFK as the New York airport. The airline is betting that enough travelers will pay extra to skip the stop, and its own disclosures now make it possible to test that bet from outside. This analysis separates figures Qantas has published, third-party estimates, and Airways scenarios. None of the modeled figures is Qantas's route profit.

Fewer Seats, Richer Mix

Qantas configured its Airbus A350-1000ULR (ultra-long-range) aircraft with six First suites, 52 Business suites, 40 Premium Economy seats, and 140 Economy seats. Airbus lists a typical three-class A350-1000 at 375 to 400 seats. By Airways' arithmetic, the Sunrise layout works out to about 1.25 seats per foot of cabin length, against roughly two for Airbus's typical layout.

The 98 premium seats make up 41% of the total. The investment case puts the premium share at 30% on both Qantas's 236-seat Boeing 787-9s and its 485-seat A380s. Singapore Airlines (SQ) took a different approach on its Newark (EWR) nonstops: its A350-900ULR was delivered in 2018 with 161 seats and no economy cabin.

In the Airways scenarios below, the premium cabins produce 77% to 80% of passenger revenue. Applying instead a Qantas observation from its 2017 fiscal year that premium yields ran about three times economy, Airways calculates a share closer to 68%. The difference comes from the fare estimates the scenarios use, which put premium fares further above economy. On either estimate, fewer than 100 seats carry most of each flight's revenue.

Carrying Fuel to Carry Fuel

The Sunrise aircraft's additional rear center tank extends the A350-1000's range by 1,000nm, Airbus says, "with sufficient provision for diversions at the end of the flight." Qantas and that Airbus announcement describe a 20,000l tank; Airbus's July flight-test account gives its capacity as about 5,500 US gal (20,900l). Airbus's announcements say the maximum takeoff weight has increased but do not give the new figure. Airways has examined the engineering behind the aircraft separately.

Fuel loaded for the final hours has to be lifted out of Sydney, and carrying that weight raises burn in the early hours. By Airways' estimate at a nominal fuel density, full tanks weigh about 330,000 lb (151 tonnes), close to half the standard A350-1000's 714,000 lb (324 tonnes) maximum takeoff weight. Airbus says its long development flights in July were meant to show the aircraft could handle a 23-hour block, covering the planned flight time plus holding, diversion, and taxi time. Airways covered the aircraft's 24-hour return test flight from Melbourne.

Stronger headwinds or longer routings add fuel that must displace payload. Qantas's Perth to London case study says that when Middle East carriers were heavily constrained in 2026, a Singapore stop was introduced on the Perth (PER)–London flight "to maintain full passenger load." Before the stop, the Boeing 787-9 on the route flew with payload restrictions, limiting passengers and cargo to leave room for fuel.

Qantas says the A350 offers up to 25% more belly space than the 787-9. Its footnote calls that "theoretical volumetric capacity" and says actual uplift depends on route, weather, weight, and fuel. Airways' model does not assume meaningful cargo revenue on the longest sectors.

The Premium Qantas Expects

Before its 2018 launch, Qantas expected the Perth–London nonstop to earn roughly the same revenue per available seat kilometer (RASK) as its one-stop via Singapore. The case study says it has instead averaged a RASK premium above 20% from FY19 to FY25, fiscal years that end June 30. The 1H26 investor presentation puts that advantage over the Sydney–Singapore–London flights at 22% in the six months to December 2025. The FY26 annual report shows what Qantas calls its non-stop London service filling 95% of premium seats and 89% of economy seats, in a year that included the Singapore stop from March.

For Sunrise, Qantas Group CEO Vanessa Hudson told a media briefing that "the premium to the one-stop is about 20%," Executive Traveller reported in its analysis of Project Sunrise fares. The case study plans on a load factor of about 85%, with premium cabins above 85%, and targets RASK more than 30% above Qantas's A380 service via Singapore once the richer cabin mix is included. In Airways' base case, a 20% nonstop premium accounts for about AU$107,000 of a flight's modeled revenue.

Qantas expects Project Sunrise to add about AU$400m a year in earnings before interest and tax (EBIT) at scale. That figure spans three value pools. Six aircraft are allocated to new Sunrise routes, and six will replace 787-9s on existing ultra-long-haul routes, freeing those 787s for redeployment. Freight growth, the third pool, is counted across all aircraft. Qantas says the target has not changed since 2022 despite higher fuel costs, a weaker Australian dollar, and higher labor and airport costs.

Long Hours, Few Departures

Qantas's route releases and investor decks do not give Sydney–London block times. Airways' rotation arithmetic assumes about 21 to 22.5 hours westbound and 20 to 21.5 hours eastbound, plus turns. On that basis, one daily London service would need two aircraft at the shorter block times with Heathrow turns under three hours, and three at the longer times or with a seven-hour turn. The case study says Qantas will preserve its early-morning Heathrow slot pair for the Sydney flight; on Perth–London, that slot pair leaves the aircraft on the ground for about seven hours. Sydney–New York, at around 18 hours outbound, would likely need two aircraft. Qantas expects five aircraft by November 2027, the month after London service is due to begin.

The Qantas releases and investor decks reviewed do not describe its spare-aircraft plan or how it would recover an aircraft grounded at JFK. The 12 other A350-1000s Qantas has on order are standard aircraft, which Airbus distinguishes from the ULR by the rear center tank. Longer sectors mean fewer takeoff and landing cycles per flight hour, which eases cycle-driven maintenance, while flight hours accumulate quickly.

Qantas plans to train more than 360 pilots and 1,200 cabin crew for the 12 aircraft. By Airways' arithmetic, that is at least 30 pilots and about 100 cabin crew per airframe. Airbus fitted a twin flight crew rest compartment and an eight-berth cabin crew rest. The Qantas releases reviewed do not say how many pilots or cabin crew will staff each flight.

Nonstop Against One Stop

Removing the stop saves one set of landing charges, a second takeoff and climb, and the ground time of a transit stop. For passengers who change aircraft at the stop, it also removes the risk of a missed connection. On London, the trade is a smaller aircraft than the A380 that must carry its entire fuel load from Sydney. In Airways' base case, fuel works out to about AU$1,470 per passenger on a full-length London sector.

The Airways Model

Airways built three illustrative scenarios for one Sydney–London sector. Fares are Executive Traveller's cabin estimates, derived from October 2027 one-stop fares plus 20% and rescaled for each scenario's premium. Airways assumes 80% of those headline fares is retained as revenue after taxes, discounts, and redemptions. Fuel assumes 90% of tank capacity is burned at the IATA price above. Crew, airport, maintenance, and ownership costs are not modeled.

The largest lever is one outsiders cannot see: how much of each headline fare Qantas actually keeps. Among the variables readers can track, a 20% rise in fuel does about as much damage as filling 10 fewer of every 100 premium seats, and roughly as much as halving the nonstop premium. A 10-point fall in economy load costs about a quarter as much.

Where the Case Is Exposed

Qantas faced an AU$610m fuel cost increase in FY26, net of hedging. At late-September 2026 prices, the fuel burned on a maximum-length sector is worth nearly half of Airways' base-case passenger revenue.

Airspace is harder to hedge. Perth–London showed in March 2026 how quickly closures can force a stop into a nonstop schedule, and the 21 hours and 40 minutes of flight time Qantas intends leaves little room inside the 23-hour block, including holding, diversion, and taxi time, that Airbus set out to demonstrate.

Demand is thinner on the Pacific. Qantas's investment case puts city-pair traffic between London and Sydney at about 12,100 passengers a week in 2025, against about 2,500 for New York–Sydney, so the New York service is likely to depend more on new demand and connecting passengers.

Qantas's figures suggest travelers have paid for time saved between Perth and London. Project Sunrise asks for more: enough premium passengers, every day, paying enough over a one-stop fare to cover a flight whose fuel burn alone, at late-September 2026 prices, is worth close to half its passenger revenue in Airways' base case.
