Singapore Airlines will retire its final Boeing 737-800 in the coming days, capping a multi-year transition from inherited SilkAir cabins to a consistent, long-haul-grade experience across the fleet. The last aircraft, 9V-MGN (≈10 years old), is rostered to work short hops from Singapore Changi (SIN) to Kathmandu (KTM) and Penang (PEN) before bowing out on Sunday, October 26, 2025.
Why This Matters
With the 737-800 gone, every SIA aircraft will offer:
-
Lie-flat Business Class (no recliners left in the system)
-
Inflight Wi-Fi
-
Seatback entertainment in all cabins
It’s a rare level of consistency among global network carriers—and a big win for frequent flyers who value predictability on regional sectors.
Narrowbody Going Forward: 737 MAX 8 Only
SIA’s narrowbody future rests on the Boeing 737 MAX 8 (19 in service, 10 on order). The MAX 8 cabins feature:
-
10 Business Class seats in a bespoke stagger (two rows 2-2, one row 1-1)
-
Almost universal direct-aisle access in J (the only exceptions are the four window seats in the 2-2 rows)
-
Seatback screens and Wi-Fi throughout the aircraft
How We Got Here
-
SIA operated only widebodies for decades while sister carrier SilkAir ran the narrowbody network.
-
The SilkAir merger (announced 2018, executed 2021 onward) folded a mixed 737-800 / 737 MAX 8 subfleet into SIA.
-
The MAX grounding and delivery delays extended the 737-800’s service life longer than planned, leaving a handful of frames with legacy recliners and no connectivity.
-
Progressive retirements whittled the -800 count down from nine to one—9V-MGN—now headed for retirement.
Aircraft Geekery: What’s Leaving, What Stays
-
Boeing 737-800 (ex-SilkAir)
-
Engines: CFM56-7B
-
Cabin: Recliner J, no Wi-Fi, no seatback IFE
-
Role: Short-haul ASEAN/near-regional flying during the integration period
-
-
Boeing 737 MAX 8 (SIA-spec)
-
Engines: CFM LEAP-1B
-
Cabin: Flat-bed J in a staggered layout, Wi-Fi, seatback IFE
-
Role: Premium regional workhorse pairing with SIA’s widebodies
-
Network & Customer Impact
-
Product certainty: Booking a short-haul SIA sector now guarantees flat-bed J + Wi-Fi + seatback IFE—even on narrowbodies.
-
Schedule flexibility: The MAX 8’s economics and cabins let SIA deploy long-haul-grade product density on routes like Singapore Changi (SIN) – Kathmandu (KTM)/Penang (PEN)/Denpasar (DPS)/Bangkok (BKK)/Ho Chi Minh City (SGN), while widebodies backstop peak banks.
-
Fleet efficiency: One narrowbody type simplifies crew, spares, and maintenance, supporting higher reliability and uniform service standards.
A Quick Look Back: Where The 737-800s Went
At peak, SIA operated nine 737-800s; most have already exited, with several airframes migrating to operators in Australia. The final frame, 9V-MGN, closes the chapter this week.
Bottom Line
Singapore Airlines is retiring its last Boeing 737-800, delivering fleet-wide flat beds, Wi-Fi, and seatback entertainment—a clean, premium standard from regional hops to ultra-long-haul. From next week, if it’s Singapore Airlines, it’s a flat-bed Business Class—even on the short sectors out of Singapore Changi (SIN).
