Philippine Airlines has cancelled all scheduled domestic flights to and from Manila until August 18.

The move comes after the Philippines re-entered lockdown after doctors warned a surge in coronavirus cases could could push the country’s healthcare system to collapse, according to the BBC. Stay-at-home orders are now in place in Manila, added the BBC report.

Domestic flights between Clark, Cebu, Davao and cities other than Manila are not affected and will remain operational, says the airline.

The airline says it will also continue to operate international flights to and from Manila “subject to further guidelines from the authorities in line with quarantine capacity and related arrangements”.

Passengers who were booked on the canceled domestic flights will be given the option to rebook, refund or convert their ticket into a travel voucher, according to Philippine Airlines.
