Qantas will slash international flights by 90 per cent until the end of May in a fresh round of coronavirus-related cuts equivalent to grounding 150 aircraft.
Qantas and Jetstar announced today the additional, deeper reductions in their domestic and international flying schedules as travel bans intensify and consumers bunker down amid widening quarantine measures.
The national carrier's total international capacity will now be cut by 90 per cent from the end of March to at least the end of May, up from a 23 per cent fourth-quarter reduction announced last week.
Group domestic capacity will be cut by 60 per cent until at least the end of May - up from 5.0 per cent.
The route-by-route detail of the changes across Qantas and Jetstar's schedule is being worked through and will be announced in coming days.
The accelerated flight cuts come after government announced at the weekend international travellers to Australia are required to self-isolate for 14 days upon arrival.
Tourism Minister Simon Birmingham said at the weekend that airlines had enough cash reserves to remain viable for now, but did not rule out a bailout to stop Qantas and other carriers going under.
