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, please use Non-Directional Average in your report query if you would like a true breakout of POO since it includes all itineraries in a market. However, if you are looking to find the % of travelers who started their trip from the Origin airport and are outbound vs. the % of travelers who started their trip from the Destination airport and are traveling home to the Origin airport, we recommend using Directional.
