Different Allocation Systems

Abstract

Based on the London´s airports example it is obvious that there are differences between 3rd level airports. If the same coordination system would be introduced within various coordinated airports it could lead to various results. The results of analysis of intra-EU route data indicate that larger aircraft have been used at the 3rd level airports and there is no strong evidence of inefficient slot hoarding at these airports, not only before but also after the EC’s recognition of secondary slot trading. In contrast, the analysis of slot trading at Heathrow and Gatwick show that slot trading has taken place more likely within alliance and the chances have been very small for carriers to obtain slots from their actual or potential competitors. For the time being, there may be no need for additional regulatory interventions into secondary slot trading as there is little evidence of inefficient slot hoarding. However, the scarce opportunity of slot trading may lead to less intense competition and then to less efficient use of slots in the long run.
