Low-cost carrier Philippines AirAsia will suspend two services operating out of Manila's secondary airport, Clark, on 1 December.
It will suspend services to Macau and Puerto Princesa, says an airline official.
On 15 December, it will also reduce its Clark-Kalibo and Clark-Davao frequencies to daily and four times weekly respectively.
The airline, which will launch a Clark-Taipei service on 16 December, plans to operate it daily instead of four times weekly, adds the official.
Innovata Schedules show that Philippines AirAsia will be the only operator on the Clark-Taipei Taoyuan route and it competes with Cebu Pacific on the Clark-Macau route.
Flightglobal's Ascend Online database shows the carrier operates two Airbus A320 aircraft.
