Under what delay circumstances is a delay benefit not provided?

There is no restriction on permissible circumstances for a delay. A benefit will be provided as long as a flight is formally reported by the airline as a qualifying delay within a 24-hour period. Flights that are cancelled or rescheduled for the next day (24 hours after the flight's scheduled departure time) will not be deemed as delayed and will be handled by the airline directly via their own compensation process.
