Turkish Airlines Opens Sydney Singapore Seats October 26

Turkish Airlines will reroute its Sydney to Istanbul service through Singapore Changi Airport from October 26, 2026, replacing the current Kuala Lumpur stopover with five weekly Airbus A350 flights that travelers can book as standalone Sydney to Singapore seats. The airline confirmed the switch for the start of the northern winter schedule, and Singapore based aviation press Mainly Miles reports that tickets for the new Singapore Sydney sectors are already on sale in both directions.

If you are flying between Sydney and Singapore or onward to Istanbul after late October, check your itinerary now because the stopover city, the flight numbers and the aircraft positioning all change on that date. Our Turkish Airlines guide explains the onboard product you will find on these A350 services, including the lie flat business class cabin that now competes directly on one of Australia busiest international corridors.

Sydney Singapore Seats Go on Sale Under Fifth Freedom Rights

The important detail for Sydney travelers is the traffic right behind the reroute. Turkish Airlines has secured fifth freedom rights for the Sydney to Singapore sector, which means it can sell seats between those two cities to any traveler, as Air Traveler Club reports. You do not need to be flying all the way to or from Istanbul to board these flights.

That puts a Star Alliance widebody with lie flat business class directly into the contest on a corridor now served by Qantas, Singapore Airlines, Scoot and British Airways. Mainly Miles notes that the Singapore to Sydney route is one of the busiest international corridors out of Australia, so a fifth full service option gives price conscious premium travelers genuine leverage when comparing fares and schedules for late October onward.

What Changes on October 26 for Sydney Istanbul Bookings

Since launching Australian flights in 2024, Turkish Airlines has routed its Sydney service through Kuala Lumpur, and that intermediate leg is the part being swapped for Singapore. The airline already operates its Melbourne to Istanbul service through Changi as TK168 and TK169 three times weekly, so from late October both Australian gateways will stage through Singapore.

The commercial logic is straightforward. Turkish Airlines holds no fifth freedom rights between Kuala Lumpur and Sydney, so only passengers ticketed through to Istanbul could occupy the second leg. Mainly Miles reports that this typically meant flying a half full aircraft for a significant part of a very long rotation, while the Changi staging lets the airline sell Singapore to Melbourne tickets on a standalone basis today and extend the same treatment to Sydney.

TK23 and TK22 Timings in Full

Outbound flight TK23 departs Sydney at 9:00pm, lands in Singapore at 3:20am the following morning, then continues to Istanbul with arrival at 11:20am local time. The Singapore transit window runs just under two hours, so connecting passengers should allow for that pace when booking onward flights from Changi rather than assuming a relaxed transfer.

The return leg, TK22, 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 suits travelers who want a full day in Singapore before the final leg home, and the overnight timing in both directions keeps daylight hours free at either end of the trip.

Turkish Airlines will operate from Changi Terminal 1, where eligible passengers can use the Marhaba lounge. Star Alliance partner lounges sit elsewhere in the airport, so check lounge eligibility before counting on a specific facility during a long transit. If you are building a longer stopover, our Istanbul area guide compares six neighborhoods for the nights before or after the long haul sectors.

Singapore Becomes the Sole Australia Staging Post

The reroute consolidates the carrier Australian footprint around a single Asian hub. Alongside the five weekly Sydney frequencies and the three weekly Melbourne frequencies, the airline increases its weekly A350 movements at Changi and strengthens its operational base in a market long dominated by Singapore Airlines. Air Traveler Club reports that the schedule runs through March 27, 2027, covering the full northern winter season.

Indicative return fares for the Sydney to Singapore sector currently appear around 1,432 dollars on aggregator searches cited by Air Traveler Club, which positions Turkish Airlines as a full service competitor rather than a budget alternative on this corridor. Treat that figure as a snapshot rather than a promise, since fifth freedom launch pricing often moves as cabins fill and rival carriers respond.

Separately, the airline continues to study nonstop Istanbul to Sydney services with specially equipped long range aircraft, as covered in our earlier Turkish Airlines Sydney nonstop report. That ambition sits apart from this winter schedule change, so judge October bookings on the via Singapore routing that is actually ticketed today.
