World-leading Airport Slot Coordination System
PDC provides the world leading solutions for airport slot coordination. Covering 64% of all IATA level 2 & 3 airports.
Airport Slot Coordination System
PDC is the world-leading supplier of an airport slot coordination system for long-term airport capacity management at facilitated and coordinated airports. In addition, assessing whether flight schedules can operate safely at airports of any size requires a clear overview of resource utilisation, available capacity, and environmental regulations.
Furthermore, our solutions provide decision support to airport operations management and to the authorities responsible for approving flight operations within capacity limits. As a result, airports can efficiently monitor and evaluate runway capacity, parking stands, gates, check-in desks, passenger flows, terminal congestion, and quota limits related to operational or environmental requirements.
Finally, it is equally important to monitor daily operations to ensure compliance with on-time performance and slot usage.
Products in the Slot Coordination Solution
Without an Airport Slot Coordination System at Busy Airports, You’d Likely See:
- Delays, increased taxi / holding times for the runway
- Delays, ramp congestion as aircraft parking stand / gate is not available
- Delays, long queueing lines and waiting times in the terminal
- Poor airport experience and frustrated passengers
- Passengers missing connecting flights
All these delays increase costs by way of extra fuel, re-routing passengers, and compensation payments.
Airport Slot Coordination for All
Airports without
Capacity Issues
Use coordination tools for collecting schedules for the flight information display (FIDS).
Temporary coordination during events or specific periods.
Airports with
some Capacity Issues
Facilitated airports are not fully slot coordinated, but experience periods where demand approaches capacity — at certain times of day, week, or season.
Collect schedule for FIDS.
Airports with
Extensive Capacity Issues
The most congested airports, where demand for runway, apron, or terminal capacity regularly exceeds availability.
Mega Hubs
This coordination system provides air carriers, airports, and ground service providers allow flights operations to be submitted online and evaluated within seconds.

Why is airport slot coordination important?
An airport slot coordination system is important because it keeps air travel safe, efficient, and fair—especially at busy airports where demand exceeds capacity.
- Preventing congestion and delays
- Improve safety
- Maximise airport capacity
- Reduce knock-on delays
- Ensure fairness among airlines
- Support environmental goals
Air traffic is expected to double by 2047 compared to 2025 levels. As a result, the projected rapid and sustained growth in global flight traffic will significantly increase the need for airport slot coordination. In fact, this growth confirms that slot coordination will become more critical, more widespread, and more contentious in the future.
Therefore, reliable and robust software for slot coordination is essential. PDC SCORE is built on the Worldwide Airport Slot Guidelines (WASG) and IATA SSIM standards. Consequently, PDC SCORE is widely regarded as the preferred software solution worldwide.
How can your airport improve punctuality and efficiency?
By assigning specific time slots, airlines know exactly when they can operate. As a result, bottlenecks, holding patterns, and ground delays are reduced. In addition, runway usage is optimised, and airport resources are prevented from becoming overloaded.
At first glance, this may seem simple. However, coordination must follow several complex parameters and IATA rules. In this context, PDC brings many years of experience, where attention to detail is critical. Therefore, we are proud of our long-term partnerships, with PDC SCORE now used in 58 countries.
Why invest in fair access for airlines?
Slot coordination prevents dominant airlines from monopolizing high-demand airports. At the same time, it gives new entrants and smaller airlines a fair opportunity to compete by gaining access.
In addition, coordinators must follow fair and transparent rules when assigning or reallocating slots.
How does an airport slot coordination system support economic value and network planning?
Coordinated slots help airlines plan profitable routes and manage fleet resources. Moreover, at major hubs, slots can become extremely valuable and may even influence airline mergers or alliances. As a result, this also affects tourism, trade, and overall connectivity for the regions served by the airport.
In contrast, at congested airports, operational delays are common. Consequently, these delays increase operating costs and may require compensation payments under EU261 and other regulations.
How can an airport slot coordination system reduce environmental impact?
An airport slot coordination system like PDC SCORE can reduce environmental impact mainly by improving how limited airport capacity is used, so fewer flights operate in overloaded conditions;
- by limiting the number of flights or using quieter aircraft during noise-restricted hours (e.g., at night).
- avoiding excessive fuel burn from unnecessary idling, circling, or delays.
- supporting sustainability goals by promoting efficient use of limited capacity.
In practical terms, SCORE reduces environmental impact indirectly by using coordinated capacity controls to minimise congestion, delays, and inefficient use of runway, terminal, gate, and parking resources

Slot Coordination Testimonials
"One of the main benefits we have experienced with SCORE is its flexibility and ability to adapt to the specific needs of our airports. We coordinate 4 Level 3 Portuguese airports, each with unique operational conditions and constraints. SCORE has enabled us to accommodate these differences and implement solutions that meet the specific requirements of each airport."
NAV Portugal"PDC's SCORE system is critical to the way ACL coordinates airports around the world. The system enables our teams to manage complex coordination processes efficiently, allow customers to self help through OCS and gain access to timely, accurate information. Our long-standing partnership with PDC has allowed ACL to contribute directly to the development of the platform in line with changes in our customers needs. As aviation becomes increasingly data-driven, SCORE continues to provide the capability, flexibility and innovation needed to optimise airport capacity and deliver better outcomes for our customers worldwide."
