Jetstar is running another cheap-flights-to-Japan promotion. This time around, you can get a return fare for free when you book select Starter fares on JetStar's website. This works out to a saving of $500 or more per person. Here are the details.
To get your free return fare, head to Jetstar's website and click the Find Flights link next to your preferred travel dates. (Make sure you've ticked "Return" in the search options.) Eligible return flights will be marked "$0".
Unfortunately, the free flights are only available from the same arrival and departure ports, so if you're planning to see multiple Japanese cities you'll need to make it a round trip. Head to Jetstar's Japan Return For Free site for more information.
The offer ends 23:59 (AEST) Tuesday 19 April 2016 or until sold out.
