Regional Express says it will mandate the use of face masks for all passengers as an extra layer of protection against the spread of COVID-19.
Face masks will be compulsory on all Rex flights from June 1, 2020.
Passengers are to use their own masks and those without masks can purchase one at check-in. Passengers will be denied boarding if they refuse to wear a mask except if there are exceptional reasons.
REX has currently suspended all flights out of Armidale, but are still operating some of its other services.
Passengers must wear masks at Rex check-in counters (or worn immediately after purchasing from a check-in counter), at boarding gates, during tarmac transfer both at boarding and disembarkation (including during bus transfers), and on-board the aircraft.
Rex National Airports Manager, David Brooksby, said they needed to be vigilant to prevent a second wave of infections which would cause untold economic damage and misery.
"The health and safety of passengers and employees is paramount and we thank our passengers for putting up with the inconvenience as an act of consideration for our staff and other passengers," he said.
"Rex has already enforced significant changes to minimise the risk of infection, including the proactive and unprecedented measure of body temperature testing of passengers and employees.
"Since early March, Rex has endeavoured to space out seating allocation of all passengers to facilitate social distancing. Unrelated parties will not be assigned seats next to each other when and where possible."
