The following Philippine Airports On-Time Performance (OTP) graphs are based on the data collected by OAG Aviation Worldwide as of 10 June 2023.
On-Time is the percentage of scheduled arrival or departure time is taken as flights that depart or arrive within 15 minutes of schedule. Arriving or departing 15 minutes or after scheduled is taken as not on-time. Global OTP rankings are only assigned to all Airlines/Airports where OAG has status coverage for at least 80% of the scheduled flights. Status coverage will only be based on actual gate times rather than estimated times.
