Many passenger airlines are not getting the full potential out of their cargo businesses – particularly those that do not operate freighters. For these carriers cargo accounts for about 3% of total revenues, but ranges anywhere from next to nothing to as much as 10%. Some of this is due to hard factors like geographical footprint or type of capacity, but distribution network and the level of cargo expertise is also a key point of difference. Adding freighters can grow the cargo division’s contribution to company results but needs to be considered carefully as it can add a whole new level of risk.
