The main purpose of this study is to estimate the marginal costs of aviation infrastructure. But since it not exist a uniform definition of what is the cost base of the aviation infrastructure, there is also a discussion of what costs should be included. An additional purpose of the study is to relate the estimated marginal costs to today's pricing and to investigate whether aviation pays its socio-economic costs.

Estimates of the marginal cost of utilizing (relevant) airport infrastructure and for operating airline infrastructure is being analyzed using cost data from Stockholm Arlanda Airport and the Civil Aviation Authority. The empirical approach used to analyze cost items is a regression analysis, with adjustments for month-specific variations in travel patterns, when the airport section is investigated, and taking into account regional differences for airports when investigating air traffic control in the towers.

There are some uncertainties in the study, but in the light of this, the results indicate that the average marginal cost of the infrastructure is around SEK 13 per passenger and SEK1,168 per aircraft started. Corresponding estimation for air traffic management is also uncertain, with results indicating a marginal cost of SEK 373 per flight. Furthermore, it appears that the revenue from marginal cost-based charges could not alone finance the state aviation infrastructure.
