Slot monitoring is directed to ensure that the most efficient use of the scarce capacity is made, that an adequate level of service quality is maintained and that the quality, flexibility and effectiveness of the coordination process is improved.  In accordance with the European Council Regulation (EEC), IATA Worldwide Slot Guidelines (WSG) and local rules, Slot Coordination Czech Republic is obligated to monitor the use and adherence of allocated airport slots at Airport Prague.

Slot Tolerance

± 20 minutes
± 30 minutes for long-haul arrivals

In case of flight with the assigned slot outside time of night noise restriction, in which the block time is after landing or before take-off of the aircraft during the period of night noise from 2100 (2000) to 0500 (0400), a tolerance of 10 minutes is applied.


Our intention is to support the airlines in their on-time operation, to prevent distress of the overall airport systems and to avoid any possible misuse.

Regular Slot Monitoring

We regularly compare the most recent slot information held with the actual operated time of an airline/operator as published in the airport information systems. We also take into consideration observations received from the airport authorities, ATC and handling agents. The results will be reported to the Slot Performance Working Groups and to the Coordination Committees. We will approach an airline/operator if:

  • Flights have been operated without having cleared airport slots
  • Flights have not been operated without having cancelled airport slots
  • Flights have been repeatedly operated off-cleared slots
  • Flight have been operated by aircraft with noise category more then 1-9

Seasonal Slot Performance Monitoring

After end of season, the seasonal slot performance monitoring includes all the results of the "regular slot monitoring" and will affect the determination and eligibility of the historical precedence for an airline. Operations with significant and/or repetitive deviations might not be eligible for any historical precedence.
