Slot Allocation - Use of Slots

To help achieve the most efficient use of scarce capacity at coordinated airports and to minimize the risk of slot abuse, it is absolutely essential that airlines, once slots have been allocated to them, manage their slots portfolio in a proactive and alert manner.
In particular they should follow closely the rules and guidelines stipulated in the EU-regulation on Slot Allocation (95/93 as amended), the EUACA Community Wide Guidelines (, the relevant paragraphs in the IATA World Scheduling Guidelines (most recent edition) and in conformity with the steps outlined in the section "Slot Monitoring".
Management rules
  • Airlines can only operate flights at a coordinated airport provided the necessary slots have been allocated to them.
  • Any transfer, exchange or use other than that for which the slot was originally allocated should be reported immediately to the coordinator and is subject to final confirmation by the coordinator.
  • With reference to Article 8 bis, par. 2, sub a, of Council Regulation 95/93 as amended, the exchange of a day slot for a night slot will be declined by the coordinator. 
  • If for whatever reason an airline will not operate, transfer or exchange a slot or a series of slots, the slots should be returned immediately, even at short notice. Returned slots can often be reallocated for ad-hoc use by other airlines.
  • Airlines that intentionally hold on to slots and return them after the slot return deadline, i.e. slot misuse, (31 August for Winter scheduling periods and 31 January for Summer scheduling periods) will be given lower priority by the coordinator for the next equivalent scheduling period.
  • The following actions (a.o.) constitute slot misuse: a) Holding slots that the airline does not intend to operate, transfer, exchange, or use in a shared operation; b) Holding slots for an operation other than planned for the purpose of denying capacity to another aircraft operator; c) Requesting new slots that the airlines does not intend to operate; or d) Requesting slots for an operation other than indicated, with the intention of gaining improved priority.  
  • In case of a delayed arrival and/or departure at Schiphol Airport during the night or early morning period (see under "Declared Capacity”) an airline should inform the coordinator immediately about the circumstances that caused the delay in order to determine whether the reason for ending up in the night or early morning period can be viewed as beyond control and unforeseen (see also under "Slot Monitoring").
  • When a request is made during out of office hours, the coordinator will deal with the request at the start of the following working day. The Duty Manager at Schiphol Airport is not allowed to allocate slots to airlines. Please note that your request will not be handled before the next working day and we advise you not to resend us your request.
