Philippine aviation authorities suspend or cancel flights serving General Santos City after a magnitude 7.8 earthquake off Sarangani. The Civil Aviation Authority of the Philippines (CAAP) issues Notice to Airmen (NOTAM) advisories and limits General Santos International Airport operations, allowing only government, military, and humanitarian flights while commercial services are halted or restricted. Multiple airlines cancel itineraries as the airport closes to commercial operations and flight schedules are adjusted. Reports say landing and takeoff operations are limited initially, with the NOTAM covering the period leading up to June 11. In the days following, airlines cancel additional flights listed for June 9, June 10, and through June 11, affecting services operated by Philippine Airlines (PAL), PAL Express, and Cebu Pacific. One report cites 17 canceled flights as of late morning Monday, including inbound and outbound trips. Other reports provide updated cancellation lists by date, while CAAP later extends the NOTAM, extending the prohibition on commercial flights beyond June 11. Passengers are advised to coordinate with airlines for further updates on flight status and possible rescheduling.
