Singapore Airlines will spend more than S$2 billion (about US$1.6 billion) on new seats in all four travel classes for its long-haul fleet, the carrier said on Friday, with the first installations due in the second half of 2027. Reuters described the program as the most comprehensive cabin overhaul in the airline's history.

The spending matters for investors because premium seats are where Asia's full-service carriers earn their margins. Fuel costs have squeezed airline profits and pushed fares higher this year, while demand for business and first class has held up better than economy, according to Reuters. Singapore Airlines is betting that a stronger product will protect its yields against Gulf and European rivals on routes through Changi Airport.

What the Singapore Airlines investment covers

The program covers 72 aircraft, Reuters reported, mainly Airbus A350-900s being refitted and Boeing 777-9s on order. Together they will make up most of the long-haul fleet. The headline figure includes a S$1.1 billion A350 refurbishment plan the airline announced in 2024.

According to Future Travel Experience, 41 A350-900 long-haul and ultra-long-range jets will be retrofitted progressively. The standard long-haul A350s get the new business-class seat. The ultra-long-range A350s will carry first class for the first time. The 777-9 will have all four new cabins.

The first-class centre seats convert into what the airline calls the largest double bed in commercial aviation, using a curved layout that borrows space from the aisles. Business class gets sliding privacy doors for the first time on the airline, Reuters said.

The airline is also putting more than S$130 million into renovating and expanding its SilverKris lounges around the world. Other upgrades include 4K touchscreens and Bluetooth headphone pairing in the KrisWorld entertainment system and high-speed Wi-Fi on Starlink-equipped aircraft, Future Travel Experience reported. Collins Aerospace is supplying the first, premium economy and economy seats, and RECARO Aircraft Seating the business-class seat.

AviTrader reported that the designs drew on research with more than 5,000 frequent travellers, customers, staff and industry experts. Chief Executive Goh Choon Phong said the launch was "another step in our continuous pursuit" of better service.

Funding, rivals and the 777-9 delay

Singapore Airlines is paying for the program from its cash, which stood at S$9.1 billion at the end of June, Reuters reported. Most of the money goes to the premium cabins, because business and first-class seats cost far more per unit than economy seats. The airline has not set a spending ceiling.

Rivals are spending heavily on the front of the plane. Air France, British Airways and United Airlines are all upgrading premium cabins, and Qatar Airways plans a next-generation version of its Qsuite business class in 2027, according to Reuters. David Flynn, editor-in-chief of Executive Traveller, told Reuters the new business class looked like "a solid and much-needed catch up to the competition" rather than a big leap ahead.

The bigger risk is timing. Boeing first aimed to deliver the 777-9 around 2020, but certification setbacks, engine problems, the pandemic and closer oversight by the U.S. Federal Aviation Administration have pushed first deliveries to 2027, with Lufthansa expected to be the launch operator, Reuters reported. Chief Commercial Officer Lee Lik Hsin told the agency that the seats themselves are certified on the 777-9 but the aircraft is not.

Seat certification has become an industry bottleneck. Delays in certifying the A350 seats pushed their introduction back by about half a year, according to Reuters. Boeing Chief Executive Kelly Ortberg said recently that 787 deliveries had also been affected by seat certification problems.

What comes next

Lee told Reuters that the airline's edge does not come from cabin hardware alone. The new cabins will be on show at the APEX FTE Expo in Singapore on Nov. 18 and 19, where the airline is a headline partner, according to Future Travel Experience. The first retrofitted A350s are scheduled to return to service with the new seats from the second half of 2027, and investors will be watching whether the 777-9 arrives on its current schedule.
