Jetstar Domestic Flights - Availability

We'd like to book flights with Jetstar at the end of October from Matsuyama to Narita.
Sadly at the moment flights are only available through October 28th.

Does anyone know when flights past that date will go on sale?
I haven't found anything regarding that information so far.

Aparently only domestic flights within Japan cannot be booked beyond October 28th on their website.

Thank you very much!
Best regards

Probably in September.

According to this website,

http://air.tabiris.com/bookingtime.html

LCC start to sell tickets on the end of Jan for the end of Mar to the end of Oct, and on the end of Aug for the end of Oct to the end of Mar.

This is not the official website of any of the LCC, but as I searched Kagoshima to Kansai of Peach Aviation (one of the LCC in Japan), they don't sell tickets beyond 28th Oct.

Thanks again my friend.

I've set a "price watch" and will check the website regularly not to miss the start of the booking window.
