POO stands for Point of Origin.
% POO Origin is a percentage of passengers originating from given origin
% POO Destination is a percentage of passengers originating from given destination
% POO Other is the percentage of passengers who've started their trip elsewhere other than the True Origin. This is typical for itineraries with a long trip break or if they are two separate tickets. A trip break is defined as more than 24 hours for international travel between segments.
Please note: For analyzing POO, we recommend using Non-Directional Average in your report query.
