Definition#
Dispatch reliability measures the percentage of scheduled departures completed without a mechanical cancellation or significant mechanical delay. Industry benchmark is typically above 99%.
Why It Matters Operationally#
High dispatch reliability reduces costly cancellations, passenger inconvenience, and spare aircraft requirements. It is a function of fleet age, maintenance quality, parts availability, and engineering support.
