Airport Hubbing LevelA simple way to assess the hubbing level of an airport is to consider
the share of connecting passengers in relation to the total number
of passengers handled. A low level is related to a
small airport with no connecting flights, simply acting as an origin
and a destination. On the other side of
the range, an airport with a high percentage (above 50%) of passengers
connecting acts as an important hub in the air transport system. For
instance, Atlanta is a major air hub (Delta Airlines) with more than
half of the passengers using connecting flights to other
locations.
