Philippine Airlines honors the 24-hour cancellation rule for tickets booked directly through their channels. Passengers can cancel within 24 hours of booking without penalties if the flight is more than 7 days away. This applies to most fare types on domestic and international routes. Third-party bookings may have different terms requiring verification. https://www.informationhood.com/24-hour-philippine-airlines-cancellation-policy-fees-changes-refunds/
