Singapore Airlines cabin refurbishment delayed by seat certification issues
May 12, 2026
Singapore Airlines has delayed the launch of its long-awaited new premium cabins after certification issues with one of its new seat designs pushed the refurbishment timeline back to 2027.
The airline confirmed that the first retrofitted Airbus A350-900 long-haul aircraft will now enter service in the first quarter of 2027, instead of the previously planned second quarter of 2026.
“The revised timeline reflects industry-wide supply chain constraints, as well as a delay in the certification of one of the new seats,” Channel News Asia quotes a SIA spokesperson as saying.
The refurbishment programme is one of the carrier’s most significant cabin investments in years, valued at around S$1.1 billion ($860 million). It covers the airline’s Airbus A350-900 long-haul and ultra-long-range fleets and will introduce all-new first class, business class, premium economy, and economy products.
Certification delays hit premium seat rollouts
Singapore Airlines has not identified the specific seat involved in the program delays. However, similar certification issues have affected other aircraft interiors programs as the certification process for next-generation premium cabins is challenging and complex.
Modern long-haul premium seats have more features than earlier designs, including privacy doors and large in-flight entertainment systems, all of which must meet separate regulatory certification requirements before entering service.
Certification bottlenecks have become a recurring issue, particularly when highly customised suites are involved.
Some reports suggest the delay may involve Singapore Airlines’ new first class suite planned for the Airbus A350-900ULR fleet, though supply chain constraints are also affecting the airline’s new business class rollout.
New cabins were originally tied to Boeing 777-9
The upgraded cabins have already faced years of delays. They were originally designed for the frequently postponed Boeing 777X programme.
Singapore Airlines planned to debut the new first and business class products on its future Boeing 777-9 fleet in 2021. However, aircraft certification delays forced the carrier to shift the launch to retrofitted Airbus A350s instead.
The airline still expects its first Boeing 777-9 deliveries in 2027, which could now coincide with the delayed cabin refurbishment programme. Lufthansa, the launch airline for the 777X program, recently flew its first fully cabin-equipped 777-9.
Singapore Airlines aims to stay competitive in the premium market
The refurbishment is critical for Singapore Airlines as global competitors increase their investment in next-generation premium cabins with suite doors in business class, larger entertainment screens, and upgraded connectivity.
Singapore Airlines’ primary long-haul business class seat dates back to 2013, though the airline introduced an updated product on its Airbus A380 fleet in 2017. While the airline has maintained a luxurious cabin design over the years and the existing seat is spacious, it lacks features now common in rival premium cabins, including sliding privacy doors and modern charging options.
The new cabins will also feature upgraded KrisWorld entertainment systems and Starlink-based in-flight WiFi connectivity. Singapore Airlines recently confirmed that Starlink service would begin rolling out from early 2027 on selected A350s, A380s, and ultra-long-range aircraft.
The airline said it would unveil details of its new air travel experience later this year. Singapore Airlines stated it would “provide an update on the entry-into-service of SIA’s retrofitted A350-900 ultra-long-range aircraft at the appropriate time.” The airline intends to complete the refurbishment programme by the end of 2030.
