Qantas has halted sales for nearly all international flights until the end of March 2021.
It is not accepting new bookings for overseas flights to all destinations except New Zealand and some in the South Pacific.
The airline is not cancelling existing international flight bookings but will not accept any new reservations.
It had earlier suspended international flights through October.
It comes as Australia continues to restrict international flight arrivals and maintains Australian citizens will not be able to travel overseas for some time yet.
Sales have been suspended up to March 28 when it modifies its schedule for the northern summer 2021 season.
Customers with flight bookings from October until late March do not need to make any changes or request refunds yet but Qantas has warned that it may have to cancel some of these services in the coming weeks.
However, Qantas is still selling international tickets through its codeshare partners.
It doesn’t impact any of its domestic schedules.
