OAG has calculated the total number of all possible connections between inbound and outbound flights within a six-hour window, where either the inbound, outbound, or both flights are international, at the largest 200 airports in the world (based on total scheduled seats in July 2019) and at the largest 200 international airports (based on total international scheduled seats in July 2019) on the busiest day for global aviation over the 12 months to July 2019.
For the purposes of this analysis, in addition to the in-built business rules within OAG Connections Analyser, the following customisable criteria were chosen for all operating flights:
Single international* connections only to/from the chosen airports;
Maximum circuity of 150;
Minimum Connection Time (MCT) varies by individual airport. OAG holds the MCT information for every commercial airport in operation;
Maximum connection window of six hours;
*international connections include domestic to international, international to domestic and international to international connections
