O & D stands for " Originating" and "Destination".
So their destination is NY, it doesn't matter how many connections they make.
If their NY's heading someplace out of town, they are on the originating end.
O&D means people who either begin or end their trips at a certain place.
Atlanta for instance has a heavy amount of connections, meaning people fly through Atlanta to go someplace else. Atlanta is not their home nor their destination, they are just connecting.
In NY few people connect, because of it's location geographically and because of the heavy O&D traffic.
has been an exception, they have a rather large hub at EWR
. Even with CO
hub it's overwhelmingly served by passengers who either live in the tri-State area or are visiting the tri-State are.
