Singapore Airlines (SIA) recently filed a comprehensive update to its Winter 2025–26 network, effective from October 26, 2025, through March 2026, involving high-impact fleet swaps, seasonal route suspensions, and frequency shifts.
The highlight: in regional Southeast Asia, the Airbus A350‑900 will replace Boeing 787‑10 aircraft on key flights between Singapore–Denpasar (DPS) and Singapore–Kuala Lumpur (KUL) starting late October Similar fleet realignments are planned for Hong Kong (HKG) and Manila (MNL).
🛫 Service Suspensions in Key East Asia Markets
Demand dynamics have prompted some temporary suspensions:
- Seoul Incheon (ICN):
SQ612/611 will pause Jan 12–Feb 8, 2026, while SQ606/605 halts Feb 23–Mar 13, 2026, reducing flights from four to three daily - Beijing Daxing (PKX) operations will be suspended Jan 5–Feb 1, 2026, while select flights to Beijing Capital (PEK) will also be canceled in late 2025
- Seasonal Taipei Taoyuan (TPE) flights resume Feb 2, 2026 with four weekly A350‑900 rotations, boosting its winter capacity from 14 to 18 weekly frequencies
🌍 Long-Haul Reallocations: A380 & A350 Deployments
SIA is also realigning its long-haul operations:
- A380 Relaunch to Shanghai (PVG): From Feb 1, 2026, the superjumbo A380 returns to Singapore–Shanghai, replacing the Boeing 777‑300ER to meet increased demand
- Auckland (AKL): Starting Jan 18, 2026, the A380 is reintroduced on SQ285/286 alongside existing A350 and 777‑300ER services, signaling renewed traveller confidence in the South Pacific corridor
- Christchurch (CHC): From Nov 24, 2025 – Feb 13, 2026, weekly flights will rise to 11 to handle peak Southern Hemisphere season demand
📈 Frequency Upticks in South Asia & Korea
- Busan (PUS): From Oct 28, 2025, flights increase from four to six weekly, with daily rotations commencing Feb 1, 2026, to accommodate rising Korea-bound travel
- Colombo (CMB): Capacity boosts to 10 weekly A350‑900 services from Jan 6, 2026, reflecting robust demand between Singapore and Sri Lanka
🔄 Seasonal Restarts in Japan & Taiwan
- Sapporo (CTS) winter service resumes from Nov 30, 2025, scaling to seven weekly flights by year-end
- Taipei’s seasonal boost, detailed above, accompanies Japan’s Sapporo option, enhancing connections across Northeast Asia.
⚖️ Passenger Impact & Operational Strategy
These sweeping adjustments reflect SIA’s intentional balancing act between capacity management and maximizing returns on high-demand routes during peak travel seasons. The fleet transitions — especially the return of A380s on heavy-payload routes — and flexible suspensions signal a robust, data-driven response to shifting market trends.
Regular flyers can expect significant improvements on Southeast Asia and Oceania routes, although some East Asia networks like Beijing and Seoul will see temporary slowdowns. Long-haul travellers to Auckland and Shanghai are set to benefit from upgraded cabin options, while those aiming for Beijing or Seoul during suspension windows may need to reroute via other hubs.
📝 Planning Tips for Passengers
- Book early for A380-enhanced services to Auckland and Shanghai, starting January 2026.
- Monitor revised schedules if planning travel to Seoul Incheon, Beijing, or Taipei between January–March 2026.
- Karamba onward connections from Singapore will improve at Busan and Colombo, thanks to increased flight frequencies.
- Check alternative options or back-up plans when traveling during the service suspension windows in East Asia.
