Order of May 31, 2016 on the air traffic distribution between the airports of Paris-Le Bourget, Paris-Orly and Paris-Charles De Gaulle 

July 1st 2012 : Charles De Gaulle Airport guideline for slot swaps or transfers 

Carriers already holding slots in these timeframes before the publication of the order were individually given a night quota in accordance with the terms of the order.

A carrier without any night quota is not allowed to operate during these timeframes.

Be careful : the French DGAC approves the carriers’ flight schedules (traffic rights) provided that the airport slots are also allocated by the Coordinator, COHOR. This DGAC approval should never been interpreted as an exemption of the order of 6^th November, 2003.

The quotas for the next equivalent season are calculated in accordance with the terms of the order.

Any deleted night slot is definitely lost and cannot be re-scheduled later in the season.

Any unused night slot is also definitely lost for the current season.

Sanction process : all performed aircraft movements are systematically checked on a daily basis. The movements without appropriate slots allocated by COHOR are notified to the Authorities in charge of infringements :

•  The airport pollution control authority (ACNUSA) for the offences to the noise control regulations (especially night departures). After auditionning the airline, ACNUSA fines airlines up to 40 000€.

NB : a diversion to Paris – Charles de Gaulle airport due to the Paris –Orly airport curfew would not be considered as a reason for exemption from sanctions as the CDG noise reduction regulation is also applicable in case of operational problems.

These measures are not applicable to emergencies related to the security of flights or of persons, and take-off or landing movements related to humanitarian missions, military, medical and official flights.

Traffic to be coordinated :

All types of operations. Only Slots for scheduled traffic are coordinated from the Scheduling Conference until the slot return deadline (15 December for the Summer season and 15 July for the Winter season).

General and business aviation aircraft operators shall request their airport slots to the coordinator through the intermediary of their ground handling company.

Clearance requests (Reference IATA Standard Schedule Information Manual Chapter 6) : 

All clearance requests must be sent to COHOR via  e-mail : slots@preprod.cohor.fr

SCR’s sent by email must be plain text and not contain any logos and/or signatures!

Clearance requests will be processed during COHOR’s office hours.
Outside normal office hours ( evenings, weekends, public holidays) please consult e-Airportslots

All modifications to initial slot details must be notified to the coordinator.

When applicable, the coordinator must be informed of any joint operation/franchise/code sharing agreements prior to the beginning of such operations.
