ABSTRACT

Most of the transport of freight is cargo; goods in the form of final products transported to the markets or semi-finished products transported to assembling facilities. The main reason for choosing air transport is the short travel time. The oldest demand for aviation has been mail, due to its speed. Mail can have the form of documents like letters, or packages. Mail transport on longer distances faces increasing competition form parcel operators. A special form of freight demand is in demand for transport of parcels. A parcel can be an individual product sold at another place than where the buyer resides. Demand for aviation comes in many forms and at increasing quantities. An overwhelming challenge in fulfilling this demand is that the actual demand varies constantly on a day-to-day basis. Political turmoil or natural disasters can temporarily or permanently ruin demand for transport from and to a certain place. Fast economic developments can generate new demand quickly.
