Jetstar’s big birthday bash: Free return flights and seriously cheap travel deals too good to miss

Jetstar is offering customers free return fares on a bunch of international and domestic flights to celebrate its 21st birthday.

There are more than 95,000 free seats available on Jetstar flights, as part of a sale where customers who purchase select outbound starter fares get a ticket home at zero cost.

The offer is available across more than 80 domestic and international routes, including from Melbourne to Singapore, Sydney to Vanuatu and Adelaide to Bali.

Select domestic fares from $38 can be booked with $0 return flights, while some international fares from $154 can be booked with $0 return flights

The dates available vary depending on the route, but include early September 2025 to late March 2026 for domestic and late May 2025 to late March 2026 for international.

The 48-hour sale kicks off at midnight on Tuesday, May 6, and ends at 11.59pm AEST Thursday, May 8, unless sold out prior.

The deal is extended for Club Jetstar members, who have 12 hours of exclusive early access from midday AEST Tuesday.

Customers who are not already a Club Jetstar member can sign up when making a booking for $65.

“Over the years, we have become famous for running a huge birthday sale – and our 21st year is no exception,” Jetstar Group CEO Stephanie Tully said.

“We know that Aussies love a sale almost as much as they love a holiday, so we are proud to offer these incredibly low fares to customers as we celebrate the start of our third decade.

“Around one in three Jetstar customers travel for less than $100, and we’re committed to keeping fares low so our customers can spend more on their holiday.”

The deal is only available from the same arrival and departure ports, and travellers must pack light as checked baggage is not included.
