Singapore Airlines Upgrades 41 A350s; Premium Economy and Economy Keep Older Tech

Singapore Airlines will retrofit 41 Airbus A350s from 2027, but the electronics upgrade will differ sharply by cabin. Under the airline’s announced next-generation KrisWorld configuration, First and Business Class gain new display, audio and charging hardware, while Premium Economy and Economy retain their existing seat hardware.

The practical difference is substantial. Premium Economy and Economy on the retrofitted A350s will keep 13.3-inch and 11.1-inch screens, respectively, rather than receiving the new 4K displays. Those cabins also will not receive Bluetooth pairing for passengers’ personal headphones, USB-C ports or wireless charging. They will receive the redesigned KrisWorld software and spatial audio, so the retrofit improves the system’s interface and content without giving every passenger the same supporting electronics.

New hardware concentrates in the premium cabins

Business Class on the retrofitted A350 fleet will receive 22-inch 4K OLED touchscreens, Bluetooth audio, USB-C charging and wireless charging. The ultra-long-range A350s will also gain a new First Class cabin with 32-inch 4K OLED screens and the same Bluetooth, USB-C and wireless-charging functions.

First Class passengers will be issued Bang & Olufsen wireless active-noise-cancelling headphones. Business Class passengers will receive active-noise-cancelling headphones, while Economy passengers will continue to use wired earphones. Premium Economy will retain airline-supplied active-noise-cancelling headsets, but personal Bluetooth pairing will not be part of its disclosed A350 specification.

This creates two different kinds of retrofit inside the same aircraft. In First and Business, the work combines new seats or cabins with new screens, connection standards and device-charging equipment. In Premium Economy and Economy, Singapore Airlines says the existing seats will be “refreshed,” with the main changes arriving through common software, audio processing and connectivity rather than replacement seat electronics.

Retaining seat hardware can limit the physical scope of a cabin modification, but it also locks in the interfaces already built into those seats. Screens, headphone connections, power hardware, wiring and control units are integrated components rather than independent consumer devices that can always be exchanged one at a time. The result is a split specification passengers will notice directly, particularly if they bring wireless headphones or USB-C-only charging cables.

All cabins still receive the new KrisWorld software

The common element is the next-generation KrisWorld platform. Across all four cabins, it will provide redesigned menus, larger icons, improved search and filtering, Picture in Picture viewing and a flight-information display. A Kids’ Mode and wellness planner are also included.

The library will contain more than 2,500 entertainment options and will be refreshed monthly. Passengers who sign in with a KrisFlyer account will be able to save favorites, resume programs on later flights, receive recommendations and see gate and terminal information for connecting Singapore Airlines services from Singapore.

Starlink connectivity is planned to begin rolling out from early 2027 on the airline’s A350 long-haul and ultra-long-range aircraft, as well as its Airbus A380s. Unlimited complimentary Wi-Fi will remain available to Suites, First and Business passengers, PPS Club members, and KrisFlyer members traveling in Premium Economy or Economy. That connection could make personal devices a more capable entertainment alternative, although keeping those devices charged will depend on the hardware available at the seat.

The A350 and Boeing 777-9 will not match

The contrast becomes clearer against Singapore Airlines’ planned Boeing 777-9 cabins. The disclosed configuration for that aircraft includes 4K screens, Bluetooth audio, spatial audio and USB-C charging in every cabin. Premium Economy screens will measure up to 16 inches and Economy screens up to 13 inches.

Singapore Airlines plans to install KrisWorld on 34 long-haul A350-900s and seven ultra-long-range A350-900s. The first retrofitted long-haul aircraft is expected to enter service in the first quarter of 2027, while the timing for the seven ultra-long-range aircraft remains uncertain. The airline’s first Boeing 777-9 deliveries are also expected in 2027, following repeated delays to that aircraft program.

Passengers therefore cannot treat “next-generation KrisWorld” as one uniform hardware standard. On the 41 retrofitted A350s, the new software reaches every cabin, but the 4K displays, personal Bluetooth pairing and modern charging hardware remain concentrated at the front of the aircraft.
