Mause I 462f
Capacity management/Economic Theory: e.g. transport policy: At first glance, reducing delays leads to an increase in welfare.
Problem: this is thought too short: e.g. allocation of slots at airports: these are divided into: a) caused by the airline (technical problems with the aircraft)
Mause I 463
b) caused by the airport (infrastructure), c) deviations from the planned flight route, d) reactionary delays (caused by earlier delays); the latter is the most frequent cause. Reactionary delay: a) rotational: the return flight is delayed due to the delayed outbound flight of the same airline), b) non-rotational: a non-rotational delay occurs when a flight has to wait for passengers on a delayed flight (possibly of another airline). In this way, delays can spread worldwide.
Costs: a) Passenger time costs, b) "hard", c) "soft" costs of the airline.
Hard costs of the airline: operating and personnel costs, costs for rebooking and refunds.
Soft costs of the airline: customer losses due to dissatisfaction.
Passenger time costs: can largely be understood as opportunity costs.
Opportunity costs: in this case the time evaluated in monetary terms, which could have been used better otherwise. (1) (2)
Slots: are managed by the European Union. Capacity bottlenecks can be solved by voluntary coordination. In addition, there are many regional airports that are not fully utilized. Delays can be minimized by reducing the number of approvals and equalizing the flight plan.
Problem: from an economic point of view, minimising delays in this way does not increase welfare per se: the maximum number of arrivals and departures is reduced, thereby a) increasing average costs per flight, but also b) reducing network effects at hubs.
Network effects: Airlines are interested in hub airports because they can bundle many flights in one time window. There is then a trade-off between the network effects due to additional approvals and the increased susceptibility to delays.

Capacity reduction: makes sense from a theoretical point of view, depending on whether the airport is to the right or left of the optimum value resulting from the total cost curve at the current capacity utilisation. (3) This example can also be applied to rail traffic or platforms at railway stations (see Swaroop et al. 2012, p. 1240).
Problem: the existing practice is criticized from an economic point of view, since permits are free of charge and trade with them is prohibited. (See also Emissions Trading). The system is referred to as "off-market".
Solution: an auction of slots could generate profits.
A secondary market could ensure that the airline with the highest benefit (and thus the highest willingness to pay) would receive an approval.
