Jetstar is set to fly service JQ362 out of Western Sydney at 11am on October 25, marking the first passenger departure from the $5.3 billion government-owned airport.
The low-cost carrier has locked in a schedule of up to 21 weekly services, including 14 flights to Melbourne, four to the Gold Coast and three to Brisbane, using its Airbus A320 fleet.
QantasLink, part of the Qantas Group, will follow from March 28 2027 with four weekly flights to both Melbourne and Brisbane operated on wet-leased Embraer E190 jets.
These plans sit within a five-year commercial agreement between the Qantas Group and Western Sydney Airport, which formalises capacity and route commitments.
The agreement positions Jetstar as the launch carrier for Western Sydney International, giving it early access to a rapidly growing catchment area in Sydney’s west.
Operating three domestic routes from day one allows Jetstar to test demand across leisure and business traffic, particularly on the high-frequency Melbourne corridor.
QantasLink’s delayed entry, using smaller Embraer E190 aircraft, indicates a more cautious ramp-up focused on right-sizing capacity and preserving flexibility.
For the airport, securing both a budget operator and a full-service brand under one group provides immediate route diversity and a recognisable anchor tenant.
One major uncertainty hangs over the project, ground transport.
The planned $11 billion rail line linking Western Sydney International with Parramatta has suffered delays and is unlikely to open before 2028.
The airport will operate for several years without its flagship rail connection, forcing travellers to rely on road options and potentially limiting early adoption.
Industry observers see strong long-term potential for the site, but usage in the first phase will depend on how quickly surface access improves and how aggressively airlines build out their schedules.
