The Double Connect Routes table details information about all double connections, including marketing airlines, operating airlines and stations on each segment. When the Host Airline Report Only checkbox is selected on the Scenario Analysis screen (Figure 1), the output is limited to connections involving the host airline as either a marketing airline or an operating airline.
The table is accessible from the menu Planning > Connection Reports > Double Connects, as shown in Figure 2.
