On-time performance
 

Airport operational efficiency is measured through different measures, with On-Time Performance being the primary internationally accepted standard. On-Time Performance is measured by comparing the actual on\off-block time (when aircraft moves into bay or aircraft pushes back) against the airline schedule time (slot time for IATA level 3 coordinated airports) for arrival \ departing flights. The measurement is done in accordance with the IATA (International Airlines Transport Association) universal standard benchmark which considers a 15 minute deviation from the scheduled time/ slot time as an on-time arrival\departure flight. The On-Time Performance of the airlines is averaged for a specific airport to produce On-Time Performance for the airport.​
