Singapore Airlines (SQ, Singapore Changi) has unveiled a cabin modernisation programme worth more than SGD2 billion Singapore dollars (USD1.6 billion), covering seventy-two A350-900s and B777-9s, the airline announced on November 6, 2026.

The programme covers thirty-four standard A350-900s and seven A350-900(ULR)s to be retrofitted, alongside thirty-one B777-9s on order. The new cabin products will be introduced progressively from the second half of 2027.

The B777-9s will feature new first, business, premium, and economy class seats. All forty-one A350s will receive new business class seats, while the ultra-long-range variants will introduce first class for the first time. The premium and economy class cabins on the A350s will also be refreshed.

The revised timeline represents a further delay to the A350 retrofit programme. As ch-aviation reported in May 2026, Singapore Airlines had postponed the entry into service of the first retrofitted aircraft from the second quarter of 2026 to the first quarter of 2027, citing supply chain constraints and delayed seat certification.

Singapore Airlines chief commercial officer Lee Lik Hsin told Reuters that while the airline's new seats have been certified for the B777-9, the aircraft itself has not. Repeated delays to the B777-9 programme led the airline to extend these cabin products, originally designed for the Boeing widebody, to its existing A350 fleet. However, the seats have yet to be certified for the A350 too, pushing back their introduction by around six months.

The overall investment exceeds SGD2 billion and includes the SGD1.1 billion (USD858.4 million) A350 retrofit programme announced in November 2024, which the airline is funding from its cash reserves.

SIA Engineering was previously appointed to carry out the A350 retrofits at Singapore Changi, with the programme originally scheduled for completion by the end of 2030.

According to ch-aviation data, Singapore Airlines operates a fleet of 165 aircraft, comprising fifty-eight A350-900s, seven A350-900(ULR)s, twelve A380-800s, twenty-six B737-8s, seven B747-400Fs, five B777-200Fs, twenty-two B777-300ERs, and twenty-eight B787-10s. It has outstanding commitments for seven A350Fs, thirty-one B777-9s, and three more B787-9s.
