[1/2] A passenger wearing a face mask and face shield for protection against the coronavirus disease (COVID-19) walks towards a counter in the Ninoy Aquino International Airport in Paranaque, Metro Manila, Philippines, January 14, 2021.
The ageing Ninoy Aquino international airport was early on Monday handling a maximum 15 arrivals per hour compared to 20 during normal operations, said Cesar Chiong, general manager of the Manila International Airport Authority.
The outage was the result of the unprecedented failure of both primary and secondary power supplies, he said.
Chiong said the airport had introduced its own power system in 2018 but on Sunday, both the main and backup systems failed.
The Ninoy Aquino International Airport has previously been ranked among the world's worst international gateways, with flight delays a regular occurrence, and a history of upgrades being delayed or abandoned due to disputes between the airport and contractors.
