Turkish Airlines reroutes Sydney-Istanbul flights via Singapore Changi from October 2026

Quick summary

Turkish Airlines will reroute its Sydney–Istanbul service through Singapore Changi Airport from 26 October 2026, replacing the current Kuala Lumpur stopover and activating fifth-freedom rights on the Sydney–Singapore corridor. The carrier will operate five times weekly on Airbus A350-900 aircraft under new flight numbers TK22/TK23, with the schedule running through 27 March 2027. Sydney travelers gain a new full-service option on one of Australia’s busiest international routes, alongside Qantas, Singapore Airlines, Scoot, and British Airways.

The fifth-freedom designation means Turkish can sell Sydney–Singapore seats independently, not just as part of an Istanbul itinerary. That puts a Star Alliance widebody with lie-flat business class directly into the competitive mix on this corridor.

From the last Sunday of October 2026, Sydney passengers heading to Singapore will have a new option they didn’t have the week before: a full-service A350-900 operated by Turkish Airlines, departing at 9pm and arriving at Changi at 3:20am. The airline confirmed the rerouting of its Istanbul service away from Kuala Lumpur, effective with the northern winter schedule on 26 October 2026.

This isn’t just a schedule adjustment. Turkish has secured fifth-freedom traffic rights for the Sydney–Singapore segment, which means it can sell that city-pair independently—competing head-to-head with incumbents on one of Australia’s highest-volume international routes.

The change consolidates Turkish’s Australian footprint around a single Asian hub. The carrier already operates Istanbul–Singapore–Melbourne under flight numbers TK168/TK169, and from late October, both Australian gateways will route through Changi. Combined, that increases Turkish’s weekly A350 movements at the airport and gives the airline a stronger operational base in a market long dominated by Singapore Airlines.

For travelers, the practical effect is a new premium choice on Sydney–Singapore, plus a competitive one-stop path to Istanbul and onward into Turkish’s European and Middle Eastern network.

What the schedule actually looks like

Outbound TK023 departs Sydney at 9:00pm, lands in Singapore at 3:20am the following morning, then continues to Istanbul, arriving at 11:20am local time. The Singapore transit window is tight—just under two hours—so connecting passengers should factor that in when booking onward flights from Changi.

The return leg, TK022, leaves Istanbul at 3:50pm, reaches Singapore at 7:40am the next day, and touches down in Sydney at 7:05pm. That evening Sydney arrival is useful for travelers who want a full day in Singapore before the final leg home.

Turkish operates out of Changi Terminal 1, where eligible passengers can access the Marhaba lounge. Star Alliance partner Singapore Airlines’ flagship lounges sit in Terminal 3—a detail worth knowing if you’re planning a long transit and expecting SilverKris access.

Executive Traveller first reported the operational specifics of the Sydney routing, including terminal and lounge details. The Flightradar24 blog documented Turkish’s Australian expansion history, including the December 2024 Sydney launch via Kuala Lumpur and the original Melbourne entry. Indicative return fares for the Sydney–Singapore sector currently appear around $1,432 on aggregator searches, positioning Turkish as a full-service competitor rather than a budget alternative on this corridor.

For travelers planning flights from Australia to Singapore, Turkish’s entry from October adds a fifth distinct carrier option on the route.

Why Singapore, and why now

Turkish Airlines entered Australia through Melbourne in 2023, routing via Singapore from the start. When it added Sydney in December 2024, it chose Kuala Lumpur as the intermediate stop—a different hub, a different operational footprint. The October 2026 shift brings Sydney into alignment with Melbourne, giving the airline a single consolidated Australian operation anchored at Changi rather than split across two Asian airports.

That consolidation matters operationally. Ground handling, crew positioning, and slot management all become simpler when both Australian services touch the same hub. It also strengthens Turkish’s hand commercially: more weekly frequencies at Changi means more leverage in a market where Singapore Airlines is both a Star Alliance partner and a direct competitor on the very same city-pair.

The fifth-freedom angle is the sharper edge for travelers. Fifth-freedom rights allow an airline to carry passengers between two foreign countries as part of a service that originates or terminates at home—in this case, Istanbul. Turkish had to negotiate those rights with both Australian and Singaporean authorities, and the fact that they’re in place for the Sydney sector (as they already are for Melbourne) signals a deliberate commercial strategy, not just a routing convenience.

How to approach this route from October 2026

Turkish’s fifth-freedom service launches into a competitive corridor where full-service and low-cost options already exist—the value depends entirely on how its fares, schedule, and cabin stack up against alternatives on your specific dates.

• Compare fares across all five carriers before booking. Check Turkish Airlines’ own site alongside Qantas, Singapore Airlines, and Scoot on major OTAs. Turkish’s current indicative pricing around A$1,432 return positions it as a full-service option, but promotional fares may shift that picture closer to launch.
• Check the A350-900 seat map before committing to business class. Turkish’s lie-flat product on this aircraft is competitive, but the Turkish Airlines Australia booking page lets you verify cabin configuration and seat availability directly.
• Factor in the Changi transit if connecting onward. TK023 arrives Singapore at 3:20am with a 5:05am departure to Istanbul—under two hours on the ground. That’s workable for a transit, but leaves no margin for delays. The return transit (7:40am arrival, 9:20am departure) is similarly tight.
• Star Alliance frequent flyers should check award space early. Turkish’s Miles&Smiles program and reciprocal Star Alliance earning make TK22/TK23 worth considering for points accumulation, but award inventory on new routes tends to be limited in the first months of operation.
• Istanbul connections benefit from the timing design. TK023 is scheduled to deliver passengers into Istanbul at 11:20am, which aligns with morning departure banks for European destinations—useful if Istanbul is a connection point rather than a final stop.

Watch: Turkish Airlines’ schedule filing for the northern summer 2027 season will indicate whether the Singapore routing becomes permanent or reverts to Kuala Lumpur—and whether five weekly frequencies expand toward daily service.
