Virgin Australia says it is likely to cut more domestic flights as the nation prepares to bunker down following new coronavirus travel restrictions.

Virgin said on Monday it expected its domestic schedule to be hit by travel bans introduced by the states and the federal government at the weekend.

The airline last week reduced domestic capacity across Virgin and Tigerair brands by 50 per cent and ceased its international operations in response to tightening quarantine measures.

Virgin said more information would be provided in coming days.

Regional airline Rex entered a trading halt on Monday pending an announcement to the ASX that it will cease passengers services in all states except Queensland.

Elsewhere, Dubai carrier Emirates has slashed its passenger flight destinations to 13, down from 145.

The state-owned carrier said it would still fly to Australia, the US, Britain, Japan and Canada.

The United Arab Emirates, which is home to Dubai and Abu Dhabi, has all but closed its borders to travellers. There are exceptions for those transiting through or returning.

It also said the company would reduce salaries for the majority of its employees for three months. It will not cut jobs.

Airlines around the world are struggling to cover their costs and pay salaries with their fleets grounded and countries shutting their borders to travellers.

In a statement released on Sunday, Emirates said it had tried to maintain passenger flights “for as long as feasible” to help travellers return home amid expanding travel bans, restrictions, and lockdowns.

Emirates Group chief executive and chairman Sheikh Ahmed bin Saeed Al Maktoum described the situation as “an unprecedented crisis” and said “the world has literally gone into quarantine” due to the virus.

Air and travel companies have been among the hardest hit by the coronavirus pandemic as demand plummets amid government-imposed bans and calls for increased social isolation measures.

Qantas has also reduced its domestic capacity.
