Airport Charges

One of the principal functions of the Commission is to regulate the level of revenues that the Dublin Airport Authority may collect in airport charges levied on users at Dublin airport. The Commission is also designated as Ireland's Independent Supervisory Authority for the purposes of the Airport Charges Directive, responsible for ensuring parties comply with their obligations regarding consultation about airport charges and service quality and the provision of information.

What are Airport Charges?

For regulatory purposes, airport charges are

  •  Runway landing and take-off charges
  •  Aircraft parking charges
  •  Charges for the use of an air bridge 
  •  Passenger processing charges

Airlines that include a breakdown of the taxes and charges sometimes include an item for airport charges. Interested parties will need to check with the airlines to establish exactly what charges are captured by this item; it may not accord with the definition of airport charges that the Commission regulates.

How are Airport Charges Regulated?

When setting the price cap the Commission has three statutory objectives:

  1. the efficient and economic development of Dublin Airport
  2. the ability of the Dublin Airport Authority to operate in a financially viable manner 
  3. the protection of the interests of users and potential users of the airport

The Commission also has to have regard to a number of statutory factors.

To date the Commission has chosen to employ price-cap regulation, applied to a single till. Price-cap regulation is a form of incentive regulation. The Commission announces in advance a cap on the total revenues per passenger that the DAA may collect. This cap lasts for a period of four or more years. If the DAA can successfully reduce its costs below the level of the cap, the airport operator keeps the value of these savings until the cap is reset. At the time of the next price cap, the Commission will consider the level of costs that the airport operator was able to realise when setting the next price cap. Consequently the airport operator and users share the benefits of any cost savings that the DAA is able to realise. The incentives for the airport operator to realise costs savings ultimately should benefit users as well as the airport.

The price cap is derived from a series of inputs known as ‘regulatory building blocks’ which are calculated by the Commission at the time of a price cap determination. These building blocks are

  • The regulatory asset base (“the RAB”) which in any given year is the sum of existing capital stock and a forecast of efficiently incurred new capital stock
  • A return on an efficient capital stock
  • Plus a depreciation charge on that capital stock
  • Plus an estimate of efficiently incurred future operating expenditures
  • Less an estimate of future commercial revenues

The sum of these building blocks is divided by a forecast of passengers (also a building block) to give the maximum per passenger airport charge. 

What is the Current Cap on Airport Charges?

The provisional 2020 price cap at Dublin Airport is €7.58 per passenger. This maximum revenue per passenger is subject to DAA achieving certain quality of service targets. In addition, it could either increase or decrease if triggers for capital projects are reached. Further information on how the price is calculated, the quality of service targets and triggers for capital projects can be found in the 2019 Final Determination

The Commission checks that the DAA has complied with the price cap annually. It publishes quarterly reports summarising how the DAA has fared against the various quality of service metrics outlined in the determination.
