Travellers booking Singapore Airlines premium economy are heading into a strange situation: two noticeably different cabins sold under the same name, and the better one is years away from flying. When the airline outlined its next-generation KrisWorld entertainment system on October 22, one detail stood out — the brand-new premium economy seat, with a screen up to 16 inches (41cm), is reserved exclusively for the Boeing 777-9. The 41 Airbus A350s getting the S$1.1 billion retrofit will keep their 2015-era seats, refreshed but fundamentally unchanged.
The new seat itself is a serious piece of kit. Collins Aerospace builds it, Factorydesign handles the design, and the spec includes a 40-inch pitch, 19-inch width, 9-inch recline, adjustable leg and footrests, Bluetooth audio, USB-C and a 4K screen — with some aircraft getting 4K OLED displays. That's a bigger screen than business class offered a generation ago.
So why leave it off the A350s? Boeing's delays are the main reason. The seats were developed around the 777-9, which first flew in January 2020 and still isn't certified, with first deliveries now targeted for 2027 — roughly seven years behind plan. Rather than wait, Singapore moved its new first and business class products onto 41 A350-900s in a retrofit announced in November 2024. Premium economy didn't come along, partly because the new seats aren't yet certified for the A350, and partly because the retrofit concentrates on cabins with the strongest revenue pull. On the ultra-long-range A350s flying routes like the nearly 19-hour nonstop to Los Angeles, premium economy shrinks from 94 seats to 58 while first class suites and business seats grow. The airline's own executives have said business class sells easily on those flights; premium economy needs aggressive pricing to fill.
Timing is the catch. Singapore points to 2027 for the first 777-9s with the new cabin, but its fleet plan shows no deliveries before April 2027, Emirates, Qatar and Lufthansa are ahead in the queue, and analysts like View from the Wing think 2028 is more realistic. Meanwhile the retrofitted A350s — debuting new first and business class from early 2027 — will be flying well before the 777-9 arrives. Around 1,220 older premium economy seats across the A350 fleet will outnumber the new ones for years.
For travellers, the practical takeaway is to check the aircraft type before booking premium economy, especially once both cabins are in service. An A350 ticket gets you the 2015 seat with its older screen; a 777-9 ticket eventually gets the all-new design. Singapore hasn't explained how it will flag the difference to buyers, and the outcome partly depends on Boeing's delivery line, which the airline doesn't control. If you're flexible, waiting until the 777-9 enters service could be worth it — but don't book around it until a delivery date is actually confirmed. Details on the new first and business seats were unveiled on November 7, which should round out the picture of what the next-generation cabins will look like.
