ALLOCATION PROCESS

PRINCIPLES

Air carriers operating to and from coordinated airports must submit a request for the allocation of landing and/or take-off slots to the coordinator and receive approval before operating. According to Article 2, paragraph G, of Council Regulation 95/93 state flights, emergency landings and humanitarian flights are exempted. Messages must be sent through the SCR format (Slot Clearance Request/ Response) in conformity with chapter 6 of the IATA Standard Schedules Information Manual (SSIM). Processing may take up to three full business days

All requests must be submitted in UTC times. When a slot cannot be allocated as requested, offers made by the coordinator will be valid for the duration of three full business days. If no reply is received, the offer will be cancelled without notice.

ACNL is working according to the IATA Scheduling process. The milestones of the IATA Scheduling process can be found in events and the IATA Activity Calendar on https://www.iata.org/en/policy/slots/.
