Ground Delay Programs and Collaborative Decision


An important question is how the new slots are distributed among the different air carriers during the GDP. Initially, the distribution is based on the rule of first come, first served. Accordingly, air carriers provide the aviation administration with their planned (static) schedule of flight arrivals at the different airports. During a GDP, the available landing slots are allocated to the air carriers based on this static schedule. For example, in Figure 18.3, Case (a) shows the static schedule of flight arrivals, where 14 flights are scheduled to land at the airport. In

Case (b), during the GDP, ten landing slots are available at this airport (A through J). According to the first-come-first-served rule, flights 1 through 10 are assigned to slots A through J, respectively. No slots are available for flights 11 through 14. These flights have to be cancelled or diverted to other adjacent airports.
