Scoot (TR, Singapore Changi) will take over some of the routes left unserved by the demise of Jetstar Asia Airways while sibling carrier Singapore Airlines will increase frequencies on other routes. Both Scoot and Singapore Airlines are part of Singapore Airlines Group.

A spokesperson told local news outlets that Scoot would start flying between Singapore and Okinawa Naha, Medan Kuala Namu and Labuan Bajo, subject to regulatory approval and other commercial considerations, once Jetstar Asia Airways ends its flights there. That airline is the sole operator on both routes.

Earlier this month, Qantas Group announced that it would permanently close its Singapore-based low-cost carrier on July 31, 2025, citing rising supplier costs, high airport fees, and intensified competition in the region. Jetstar Asia Airways flies to 18 airports across nine countries from Singapore.

The Singapore Airlines Group spokesperson said the company's two airlines would either take over or increase frequencies on nine routes across Malaysia, Thailand, Sri Lanka, Indonesia, and the Philippines as a result of the Jetstar Asia Airways closure. Other routes are served by at least one other operator.

At this point, Singapore Airlines Group has not said whether it will take on the routes Singapore-Broome and Singapore-Wuxi. Both are serviced only by Jetstar Asia Airways.
