Airports And Airlines: The Complex Relationship

how can an airline get a spot at an airport

Airport slots are an important part of airline operations, giving them the right to take off and land at a specific airport at a designated time. These slots are managed by the IATA 'Worldwide Airport Slots Group' and are controlled locally by aviation authorities. The process of securing an airport slot is based on a series of rules developed by the IATA over many years, with the Worldwide Airport Slot Guidelines (WASG) being the foundation of the global slot allocation process. Slots are scarce at many airports, and the rules for selling them vary between regions. Airports can attract more airline services by lowering costs, changing their pricing structure, and accommodating new airlines.

Landing slots are permissions for airlines to use airport infrastructure at a specific time

Landing slots are an important part of an airline's operations. They are permissions for airlines to use airport infrastructure at a specific time. This includes the runway, taxiway, gate, terminal, and other facilities. These slots are crucial for keeping flights running efficiently and preventing overcrowding, especially at busy airports.

There are different types of landing slots, including arrival, departure, seasonal, ad-hoc, night, cargo or freight, standby, secondary, and transfer slots. Each type serves a specific purpose, such as managing incoming and outbound air traffic or accommodating cargo operations.

The allocation of landing slots is a complex process managed by the International Air Transport Association's (IATA) "Worldwide Airport Slots Group" and local aviation authorities. Airports are categorized into three levels: Level 1 (non-coordinated), Level 2 (slot-facilitated), and Level 3 (coordinated). Level 3 airports, which are the busiest, require strict slot controls to manage their tight schedules.

Airlines can apply for landing slots, and airports approve these requests based on available capacity. Slots are scarce at many airports, and airlines must utilize them to retain their allocation. Slots can be exchanged or traded between airlines, and their value varies depending on the airport, time of day, and other factors.

To attract airlines, airports employ various tactics, including marketing, competitive pricing, and showcasing their ability to accommodate new entrants. The dynamics between airports and airlines are complex, and efficient slot management is crucial for the smooth functioning of the global aviation system.

Airlines can apply for a slot, which is approved if the airport is not at capacity

Airlines require airport slots to take off and land at a specific airport at a designated time. These slots are particularly important at busy airports, where they can become scarce. Not all airports use slots—only those that are at risk of congestion. Airports that are not at capacity can approve an airline's application for a slot.

The allocation of airport slots is based on a series of rules developed by the International Air Transport Association (IATA). The Worldwide Airport Slot Guidelines (WASG) are the foundation for the global slot allocation process. Slots are managed overall by the IATA "Worldwide Airport Slots Group" and controlled locally by aviation authorities using the IATA "Worldwide Slot Guides (WSG)".

Airlines can apply for a slot at an airport that is not at capacity. If the slot is approved, the airline will have permission to use the airport's infrastructure for take-off or landing at a specific time and date. This ensures that the aircraft have access to all the relevant infrastructure at the airport.

The process of applying for and securing airport slots can be complex and is often compared to a trader's market or a stock exchange. The value of slots can vary depending on the airport, time of day, and other factors. Some airlines may even resort to flying empty or "ghost" flights to keep their slots utilized.

Slots are managed by the IATA 'Worldwide Airport Slots Group' and controlled locally by aviation authorities

The allocation of airport slots is a complex process, akin to a stock exchange, with trading back and forth and different values for different airports, times of day, and pairs. The International Air Transport Association (IATA) categorises airports as Level 1 (non-coordinated), Level 2 (slot-facilitated), or Level 3 (coordinated). Level 2 and Level 3 airports are where slot management becomes crucial.

Slots are managed by the IATA Worldwide Airport Slots Group, which was formed in the 1970s and continues to be the foundation of the global slot allocation process. The group comprises airlines from different business models and regions, along with airports and coordinators, who come together to discuss key issues, policies, and trends, as well as set priorities for action. The Worldwide Airport Slot Guidelines (WASG) are published by the IATA in collaboration with airports and coordinators, providing a single set of standards for managing airport slots.

While the IATA provides overall management, the local implementation and control of slot allocation are handled by regional aviation authorities, such as the FAA in the US. These authorities use the WASG to guide their decisions and ensure a fair and transparent process. The guidelines aim to balance access for new and existing airlines, provide flexibility for regulatory changes, and minimise congestion and delays.

The allocation of slots is a dynamic process, with slots being redistributed when an airline fails to utilise them sufficiently, as per IATA guidelines. Slots can be exchanged or leased between airlines, and an IATA conference is held twice a year for airlines to negotiate these arrangements. This redistribution process ensures that slots are used efficiently and not hoarded, promoting competition and accessibility in the aviation industry.

Landing slots are scarce and valuable, leading airlines to want to keep hold of them

Landing slots are crucial for airlines, as they determine when aircraft can take off and land at an airport. With the remarkable growth of the aviation industry, many airports have struggled to keep up with demand, especially those serving major cities. This has resulted in a scarcity of landing slots, which has made them highly valuable.

The scarcity of landing slots has led to the development of a complex system of slot management, aimed at maximizing airport capacity use while ensuring fair competition. Airports are categorized into three levels based on their capacity and congestion: Level 1 airports have sufficient capacity to meet demand, Level 2 airports have potential congestion but can be managed through collaboration, and Level 3 airports face a significant and lasting shortfall in capacity, requiring slot allocation by a coordinator.

The process of securing a landing slot involves a series of rules developed by the International Air Transport Association (IATA) and its Worldwide Airport Slots Group (WASG). While there may be local interpretations, the overall process is consistent across airports. Landing slots are allocated based on various criteria and are divided between existing and new airlines. If an airline's requested time is unavailable, a slot coordinator can offer an alternative.

The high value and scarcity of landing slots lead airlines to want to retain their slots. Airlines may operate lower-capacity aircraft more frequently or even fly empty 'ghost' flights to maintain slot utilization. They may also lend out their slots to other airlines on a short-term basis to generate revenue and avoid losing the slot.

In some cases, landing slots can be traded or sold between airlines, with prices varying based on factors such as time of day and frequency. This trading system has been likened to a stock exchange, with the best traders having extensive experience, a network of contacts, and an intimate knowledge of the industry. While this system has been in place for decades, some argue that it is outdated and needs improvement to ensure fair access for new entrants to the market.

Airports can attract airlines by lowering costs and accommodating new entrants

Airports can be constrained for new services in several ways, such as a lack of physical gates or pricing inefficiencies. To attract airlines, they need to show airlines where they can fit and how their operations will not be constrained. Airports can also be attractive to airlines by lowering their costs. Airlines pay airports to land, park, and use indoor and outdoor spaces to check-in passengers, sort baggage, etc. High costs at airports can lead to higher ticket prices, which can deter passengers from flying. Therefore, if an airport can lower these costs, it can attract more airlines. For example, the CEO of Pittsburgh Airport has expressed a desire to make the airport free for airlines to operate, which would significantly lower costs for airlines and, in turn, create more passengers.

Another way to lower costs is to reduce the "cost per turn." This is calculated by taking all the costs an airline pays to the airport, the costs they pay for equipment and people, and dividing this by the number of operations at the airport. Airports with high landing fees, airport rental fees, and high local labor markets can have very high costs per turn. For example, New York's JFK airport has costs per turn in excess of $5,000.

Additionally, airports can accommodate new entrants by finding ways to invite and provide access for new airlines. For example, Miami Airport changed its pricing structure, which led to a lot of new flights from airlines serving there for the first time. Airports can also improve the quality of their airline service providers. For instance, in 2014, Namibia Airport Company appointed Menzies Aviation as its second ground handling provider, and the number of airlines operating there doubled by 2016.

Furthermore, destination airports can help stimulate demand for international airlines, benefiting the airline as the local relationship lends credibility and ensuring the airline continues to plan its route to that airport. Airports can also improve their infrastructure to satisfy passengers and attract more airlines. For example, Dubai has constantly built and upgraded its airport infrastructure, while many airports in Africa and the Middle East remain outdated and unattractive to passengers.
