How Airlines Use the Metric
Block Time is used to describe capacity, traffic, cost, revenue, schedule performance or asset productivity. It is most useful when the calculation basis is consistent across the periods, airlines or fleets being compared.
What the Number Can Show
It includes taxi time as well as airborne time and is widely used for crew scheduling, ACMI charging and operational performance.
Comparison Limits
Airline metrics can be distorted by stage length, fleet mix, geography, accounting treatment, seasonality and business model. A single ratio should therefore be read with the operating context and the underlying numerator and denominator.
