Singapore Airlines is adding two more weekly flights between Changi Airport and Adelaide from late October 2026, taking the route to 12 services per week – more than any international airline has ever operated year-round to and from the South Australian capital.

All 12 flights will be flown by the Boeing 787-10, the highest-capacity aircraft in the SIA fleet after the Airbus A380, with 337 seats.

Here’s what’s changing, how the route has grown over the years, and what it means if you’re planning to use miles.

Adelaide schedule boost

Between 25th October 2026 and 27th March 2027, the full northern winter 2026/27 season, Singapore Airlines will increase its Adelaide frequency from the current 10 times per week to 12 times per week.

The two additional services in each direction are:

• SQ279 from Singapore to Adelaide, the overnight service, adding Thursdays and Sundays
• SQ278 from Adelaide to Singapore, the daytime service, adding Mondays and Fridays

That has the neat effect of making the SQ279/278 pairing a daily option in both directions, something that hasn’t been offered on the route for a few years.

The SQ277/276 rotation continues to operate five times per week, with only Tuesdays and Wednesdays missing that option.

Here’s how the current schedule looks.

Note that the schedule provisionally drops back to 10 times per week from the start of the northern summer 2027 season on 28th March 2027, but we wouldn’t read too much into that at this stage.

In recent years every increase Singapore Airlines has made to its Adelaide schedule during a winter season has subsequently filtered through into the following summer season and stuck, so we’d expect this one to be extended in due course, reflecting a permanent change.

A record for the route

Adelaide has been one of the quieter success stories in the Singapore Airlines network since the pandemic, with the airline steadily rebuilding and then overtaking its pre-COVID operation.

Before COVID the route was a solid seven times weekly year-round using the 303-seat A350 Medium Haul, with a short-term peak-season boost to 10 or 11 weekly flights each December and January.

The service restarted during the pandemic at just once per week, then climbed back through three and five weekly flights, returning to daily in December 2022.

The larger 787-10 arrived on the route for the northern winter 2023/24 season, and frequencies moved up to 10 per week from the winter 2024/25 season, where they have remained ever since.

Here’s how the weekly seat count in each direction compares.

Period	Flights per week	Aircraft	Seats per week
Pre-COVID (2019, year-round)	7	A350 MH	2,121
Pre-COVID (Jan 2020, peak)	11	A350 MH	3,333
Current (since Oct 2024)	10	787-10	3,370
From 25 Oct 2026	12	787-10	4,044

That’s an extra 674 seats each way every week compared to today, a 20% increase, and it lifts the route more than 21% above what was previously its all-time capacity peak.

Crucially, that January 2020 high point was a short seasonal spike lasting a few weeks. This time it’s a season-long frequency and capacity increase, running for five months – and, we suspect, beyond.

Compared to the pre-COVID year-round operation, weekly capacity on the route will be up more than 90%.

Singapore Airlines has served Adelaide for over 40 years and remains the only airline flying non-stop between the two cities, with Qantas having pulled out of the route back in March 2013.

What it means for travellers

The obvious benefit is choice. With SQ279/278 going daily, every day of the week now offers the overnight service to South Australia, and the civilised daytime 10am departure from Adelaide up to Singapore, with mid-afternoon arrival.

For those connecting beyond Singapore, more Adelaide frequencies also means more workable timings to and from SIA’s Europe, UK, India and North Asia flights, which is historically how a large share of this route’s traffic is made up.

There’s a cargo angle too, with South Australian exporters leaning heavily on the belly capacity of these flights for premium produce heading into Asia and Europe. Two extra widebody rotations per week adds significantly to that, thanks to the 787-10s significant underfloor cargo capacity.

KrisFlyer awards

Here are the one-way KrisFlyer redemption rates you’ll pay by cabin on the Singapore – Adelaide route.

KrisFlyer Redemption Rates One-Way Singapore ⇄ Adelaide
Airline / Cabin		Saver	Advantage	Access
	Economy	29,000	60,500	87,000
	Business	72,000	103,500	133,500 to 213,500

It’s worth checking the newly-added services in particular on this route, since Business Class Saver award space tends to be more generous on flights only recently added to the booking system.

At the time of writing, the route is included in the monthly Spontaneous Escapes promotion, with 30% off Economy Class Saver awards, bringing pricing down to 20,300 miles each way in that cabin for those who can make short-term non-refundable travel plans.

In months when Business Class Saver awards are included in the same deal, it brings awards in that cabin down to as little as 50,400 miles each way, so watch out for future promotions as capacity increases, especially in off-peak months.

787-10 Business Class

With every flight on the route operated by the Boeing 787-10, Business Class passengers will be in Singapore Airlines’ 2018 Regional Business Class seat, in a 1-2-1 layout with direct aisle access from all 36 seats.

It’s a forward-facing seat that converts to a fully flat bed, and while it doesn’t have the sheer width of the long-haul products (many find a bit too narrow), it’s still a decent offering for a flight of around six to seven hours.

Fun fact: Adelaide was the global launch destination for SIA’s Airbus A350 Medium Haul in December 2018, and it flew as SQ279/278 – the very pairing now going daily. That type no longer serves the city, with the larger Boeing 787-10 used instead.

Adelaide’s wider international growth

Singapore Airlines isn’t the only carrier adding capacity into Adelaide.

Cathay Pacific returned to the South Australian capital in November 2025 with a three times weekly seasonal service, and will increase that to five times weekly this year.

China Southern, which converted its Guangzhou service from seasonal to year-round earlier in 2026, will go daily between 1st December 2026 and 10th March 2027. China Eastern also launched non-stop flights from Shanghai in June.

Taken together, Adelaide is now more comprehensively connected to Asia than at any point in its history, but Singapore Airlines remains comfortably the largest international operator at the airport.

Singapore Airlines will operate a record 12 weekly flights between Singapore and Adelaide from 25th October 2026 through to 27th March 2027, adding SQ279 on Thursdays and Sundays and SQ278 on Mondays and Fridays.

That makes the SQ279/278 pairing a daily option in both directions, with the 337-seat Boeing 787-10 operating every service and weekly capacity climbing to 4,044 seats in each direction.

It’s the most weekly flights any international airline has ever operated year-round to and from Adelaide, and comfortably a route record for Singapore Airlines, exceeding even the short-lived pre-COVID peak in January 2020 by over 21%.

The schedules currently reflect a return to 10 weekly flights from late March 2027, but based on how previous Adelaide increases have played out we’d expect this new 12 times weekly schedule to be year-round.
