Singapore Airlines has announced an investment of more than S$2 billion in cabin upgrades across all four classes, with the retrofit programme set to begin progressively from the second half of 2027. The upgrades include new seats, enhanced in‑flight entertainment and improved comfort features.

The retrofit programme will cover a total of 72 aircraft: 41 A350‑900 long‑haul and ultra‑long‑range aircraft, and 31 Boeing 777‑9s. First Class will feature the largest double bed in commercial aviation, with 32‑inch 4K high‑definition screens, Bang & Olufsen noise‑cancelling headphones and an option for a double bed.

Business Class seats will be fitted with 22‑inch 4K screens, wireless charging, and Bluetooth audio connectivity. Premium Economy seat pitch is increasing from 38 to 40 inches.

The retrofit of A350 aircraft has been delayed due to Boeing 777‑9 delivery delays; the first 777‑9 aircraft are not expected to be delivered to Singapore Airlines before 2027. New Economy Class seats will be available only on the Boeing 777‑9 aircraft and will include new 4K seatback entertainment monitors.

SIA is also investing in upgrades to its KrisWorld entertainment system, in‑flight amenities, high‑speed connectivity and airport lounges as part of the broader overhaul.

The retrofit programme is part of Singapore Airlines' ongoing efforts to enhance the passenger experience across its fleet.
