Airport Coordination Netherlands (ACNL)

What Airport Coordination Netherlands (ACNL) does

Airport Coordination Netherlands (ACNL) is an independent governing body established by public law that serves as the sole slot coordinator for the Netherlands' three Level 3 coordinated airports: Amsterdam Airport Schiphol (AMS), Rotterdam The Hague Airport (RTM), and Eindhoven Airport (EIN). Operating under EU Council Regulation 95/93 and IATA Worldwide Airport Slot Guidelines, ACNL allocates and monitors airport slots for commercial air carriers and general aviation operators, enforcing rules such as the 80% Use It or Lose It threshold and historic rights eligibility. The organization was founded in 1998, is headquartered at Schiphol Airport, and operates with a lean staff of 11 employees.

ACNL's core product is the Online Coordination System (OCS), a web-based portal at online-coordination.com that allows airlines to request, confirm, and manage slot allocations 24/7 using IATA SSIM Chapter 6 Slot Clearance Request (SCR) message format. Supporting products include an Out of Hours service for slot management outside business hours, a Slot Transfer Application for inter-airline slot transfers, an Event Calendar tracking IATA scheduling milestones, the read-only E-Airportslots.aero data portal, and published Working Procedures and Policy Rules. The Slot Monitoring System tracks usage compliance with WARN and NOTE threshold messaging, and processes capacity declarations from coordinated airports twice yearly, incorporating environmental limits and movement caps set by the Dutch Ministry of Infrastructure and Water Management.

Revenue is generated entirely through a usage-based slot fee charged to air carriers and Level 3 airports (€1.71 per used slot for April 2026 to March 2027, up from €1.63 the prior year). ACNL's customer segments are commercial air carriers (primary) and general aviation operators (secondary), with no commercial pricing for end users as the entity functions as a regulatory body. Distribution is exclusively direct through the OCS portal and email-based SCR communications. The organization consults with airlines and airports through the Coordination Committee Netherlands (CCN) and serves as the Implementing partner for European Commission slot release commitments under major merger decisions such as Air France-KLM (COMP M.3280).

Direct peers

• Airport Coordination Limited (ACL): UK's independent airport slot coordinator, performing the same statutory allocation and monitoring function as ACNL under EU Regulation 95/93 at Level 3 coordinated airports including Heathrow and Gatwick. The closest functional analogue to ACNL by mandate, regulation, and process.
• AECFA (Asociación Española de Coordinación de Frecuencias Aéreas): Spanish airport slot coordinator managing allocation at coordinated Spanish airports. Functions under the same EU and IATA regulatory regime as ACNL, providing a clear direct peer for benchmarking processes.
• COHOR (Coordination des Horaires): France's independent slot coordinator for Level 3 French airports including Paris CDG and Orly. Performs slot allocation and monitoring under EU 95/93 with the same IATA SSIM/WASG framework as ACNL, making it a direct regulatory peer.
• Assaeroporti: Italy's airport slot coordinator handling allocation at Italian Level 3 airports. Same statutory role and EU 95/93 compliance profile as ACNL, though serving a smaller traffic base.
• FHKD (Flughafenkoordination Deutschland): Germany's independent slot coordinator responsible for slot allocation at coordinated German airports (Frankfurt, Munich, Düsseldorf). Operates under identical EU and IATA regulatory frameworks as ACNL and serves a comparable traffic volume.

Others

• IATA: Sets the Worldwide Airport Slot Guidelines (WASG) and SSIM Chapter 6 standards that ACNL implements. Functions as ACNL's governing standards body rather than a competitor, but materially shapes ACNL's operating procedures.
• ILT (Human Environment and Transport Inspectorate): Dutch civil aviation authority co-publisher with ACNL of the Slot Enforcement Code. Functions as ACNL's regulatory counterpart for enforcement, not a competitor, but a critical partner in slot misuse supervision.
• EUACA (European Airport Coordinators Association): Industry association representing national slot coordinators across Europe including ACNL. Not a direct competitor but the body through which ACNL collaborates on shared issues like the JNUS recommendation for the Middle-East conflict, making it a key ecosystem participant.

Broad incumbents

• Eurocontrol: Pan-European airspace and air traffic management organization that coordinates network-level aviation flows across Europe. Adjacent to ACNL's slot-level work but operates at a different layer (airspace vs. airport slots).
• Royal Schiphol Group: Operator of Amsterdam Schiphol Airport and partner in slot coordination via capacity declarations. A broader aviation infrastructure incumbent that feeds ACNL its capacity parameters but does not compete in slot allocation itself.
