Singapore Airlines will add four long-haul routes in less than three months. Between 24 October and 1 December 2026, the carrier opens daily Dubai, five-weekly Madrid via Barcelona, daily Western Sydney and three-weekly Riyadh, all from Singapore Changi on Airbus A350-900s.
The burst adds breadth to Changi's winter 2026 schedule. Each route fills a different gap: a Gulf hub return, a southern European revival after 22 years, a new Australian gateway, and a Saudi capital link that restores a city last served in 2014.
All four were detailed by Simple Flying from airline filings. The pattern is telling. SIA is using the A350-900 to open markets at moderate risk, then upgauging where demand justifies. For passengers connecting through Changi, the new options add one-stop choices between Southeast Asia and Europe, the Middle East and Australia.
Singapore Airlines four long-haul routes at a glance
1. Singapore to Dubai (DXB) resumes 24 October 2026, daily. It starts on a 303-seat Airbus A350-900, then switches to a 264-seat Boeing 777-300ER from 28 March 2027. The service restores a link paused during regional conflict. Flight tracking data put the last operation at 28 February before the suspension, and a planned A380 deployment has been removed entirely.
2. Singapore to Madrid via Barcelona launches 26 October 2026, five weekly on a 253-seat A350-900 as SQ388 out and SQ387 back. The routing is Singapore-Barcelona-Madrid with the same aircraft continuing. The airline last flew to Madrid in 2004 via Paris on the 747-400, so this is a return after 22 years. There are no local traffic rights between Barcelona and Madrid, so sales are Singapore to either Spanish city.
3. Singapore to Western Sydney (WSI) starts 23 November 2026, daily on a 303-seat A350-900. Western Sydney International opens 24 October with Jetstar as the first carrier. SIA becomes the airport's first long-distance operator, complementing Singapore Airlines' Bali winter shift to the 737 MAX that also covers the Indonesia market.
4. Singapore to Riyadh (RUH) returns 1 December 2026, three weekly on a 303-seat A350-900. Singapore Airlines served Riyadh between 2008 and 2014, for a time one-stop via Dubai or Abu Dhabi and later nonstop and extended to Jeddah. The new service is nonstop three times a week.
What aircraft and cabins to expect
The A350-900 is SIA's long-haul workhorse for medium-risk openings. The 253-seat and 303-seat layouts offer lie-flat business, premium economy and economy without the capacity jump of the A380. That lets the airline test Madrid via Barcelona and Riyadh nonstop without flooding the market.
Dubai is the exception. The planned 777-300ER swap from 28 March 2027 suggests expected premium demand on Singapore-Dubai, a corridor where Gulf carriers operate multiple daily widebodies. The A350 range also helps SIA keep sustainable fuel surcharges transparent on tickets issued from 1 October for travel from 1 January, with distance and cabin-based tiers that are easier to manage on a single fleet type at launch.
Why these four markets now
Each route answers a network puzzle. Dubai restores a Gulf hub that feeds beyond connectivity. Madrid via Barcelona rebuilds southern Europe after a two-decade absence, using Barcelona as a tag that collects traffic in both Spanish cities without requiring two separate nonstops. Western Sydney captures the new airport's launch window before slots tighten, and Riyadh taps Saudi capacity growth as the kingdom expands business and leisure flows.
For Australia, the timing is striking. Western Sydney International is a greenfield airport in Sydney's west. SIA's daily service from 23 November makes it the airport's first intercontinental airline, a marketing edge for both the airport and the carrier as Jakarta's own gateway projects show how new airports need anchor long-haul carriers to establish transfer demand.
In Europe, the Barcelona tag is operationally efficient. One aircraft covers two Spanish cities five times a week, offering Singapore to Barcelona and Singapore to Madrid one-stop, while keeping crews and ground handling consolidated.
How to book the new Singapore Airlines flights
- Dubai daily from 24 October is bookable now for late 2026 and for 2027 after the 777 swap. Compare with nonstop alternatives from Emirates if you value schedule density.
- Madrid via Barcelona replaces a nonstop that has not existed since 2004. If you need Barcelona only, you can still book Singapore-Barcelona one-stop, but not Barcelona-Madrid alone.
- Western Sydney (WSI) is ticketed separately from Sydney Kingsford Smith (SYD). Use WSI if your final destination is Parramatta, Penrith or the Blue Mountains to save the cross-city transfer.
- Riyadh three weekly means limited frequency. If your dates do not line up, connect via Dubai on the daily service and interline to Riyadh.
All four appear in GDS as A350-900 services at launch. Check seat maps for the specific business class product on your date, as 253-seat and 303-seat A350s have different configurations.
