2. Materials and methods
2.1. Metrics The results in this paper are analyzed in terms of two kinds of performance metrics. While the first one is the straightforward total cumulative delay in the system as a function of time, the second is less conventional, and it is intended to assess the level of network delays. We have previously used it in other works concerning network-wide congestion and delay statistics (Fleurquin et al., 2013, 2013b; 2014, 2014b Campanelli et al., 2014, 2015). First, we build a daily (unweighted) airport network using direct flights as edges. Then, for each hour of the day, we extract the subnetwork containing the airports where the average hourly departure delay is above a given threshold, the value of which should be calculated over a long time period (e.g. a year or several months), so that the properties of the network can be analyzed in a stable way. As in all the metrics based on an arbitrary threshold selection, the exact results may depend on the particular value used but the general system trends must be consistent. We refer to the airports where the threshold is exceeded as congested airports, and use the size of the largest connected cluster found in the congested subnetwork as an indicator of the presence of network-wide problems. It should be noted that this quantity contains information about correlation, not causation: two airports connected in the same congested cluster may be affected by each other, but the source of the delay is not identified. 2.2. FCFS (US) model We will describe next the elements of the models starting by the simplest: the FCFS model adapted to the US air traffic. A detailed description of the modeling framework is provided at (Fleurquin et al., 2013). This model, as the SM one, needs as inputs the daily schedules of the flights that are typically extracted from flight performance data. A more detailed description of the datasets is provided in Section 2.4, but essentially the inputs needed are the scheduled arrival and departure times, aircraft and airline identi- fication codes, flights' origins and destinations, the airport capacities and the flights primary delays. Cancellations and diverted flights are not used in the model. With the aircraft code and the spatio-temporal information of the flights obtained from the data, we can reconstruct the aircraft rotations and consequently approximate the airline schedules throughout the day.
