Slots can be requested, updated and cancelled in two different methods; SCR/GCR and Online coordination. When applying for slots, airlines act in conformity with the IATA Standard Schedules Information Manual (SSIM).

ACNL is connected to the online coordination system e-Airportslots. Through e-Airportslots, airlines and operators are able to retrieve currently allocated slots, as well as – if opened for coordination actions – submit change/revises and update the waitlist.

The working procedure Instructions for slot requests for Commercial and General Aviation is applicable which describes which message format shall be used when requesting slots at AMS/EHAM.
