From the dataset, we observe that all trips in September 2017 were operated through a network of 3621 unique airports. For each airport, we estimate the total traffic by adding the number of passengers for the trips where the airport is denoted as 'Origin', the number of passengers for the trips where the airport is denoted as 'Destination', and twice the number of passengers for the trips where the airport is denoted as 'Connection' (either Connection 1 or 2). For subsequent computational efficiency, we restrict our analysis to the subset of the dataset corresponding to traffic among the 2500 busiest airports (by total traffic). This subset accounts for 98.25% of the total trips and 99.8% of the total traffic.
