Why can air freight rates be disproportionately higher (calculated kilometre-per-kilometer) for a shipment from Spokane, Washington, U.S. to Portland, Oregon, U.S. compared to a shipment from New York, U.S. to Paris, France, despite the distance between New York and Paris being ten times longer than between Spokane and Portland? Select one answer. Because transport costs are not always related to distance travelled Because there may be more competition on the Spokane - Portland route Because the volume of cargo is likely lower between New York and Paris Air freight rates are always directly related to distance travelled
