The Philippine Department of Transportation says more than 300 flights are expected to be affected by cancellations or schedule changes as Manila hosts the 49th ASEAN Summit. Disruptions are due to begin Nov. 14, when foreign delegations arrive; summit meetings are scheduled for Nov. 16–18. Officials said international flights are not expected to be canceled, though delays are possible.

Transportation Secretary Vince Dizon said affected passengers should be offered fee-free rebooking, a full refund, or travel credit. Travelers should confirm their itinerary with their airline and watch for the affected-flight lists and official advisories; authorities also anticipate traffic delays around airports.
