to complete the supply chain and functions. Where they provide with the speed of delivery, as well as a reduced risk of damage, security, flexibility and ease of access to good views of the ordinary, but the disadvantage is the high courier fees. Reynolds, Feighan (2001) and said air cargo logistics is selected 'when the value per unit weight and relatively high speed of delivery is an important factor. The properties of airfreight logistics in the following:
(1) aircraft, airports and separated. Therefore, the industries only need to prepare aircraft for its operation.
(2) it allows for faster delivery in long-haul destinations.
(3) air freight transport is not affected by the terrain.
The data indicate that the transport of goods in the market continues to grow. There is a view of the directions of global markets and logistics and air cargo also to change their services. Future directions for the development of airfreight, and integration with other transport modes, and the internationalization of the coalition, and the integration of the airlines and the pattern of the future of logistics, and air freight to cooperate with other modes of transport.

Additional logistical capacity, the positive ground is the high-level access in the wild. The major means of transport logistics land transport by rail, road transport and pipeline transport.
For rail transport to and comparative jeopardy of high endurance capacity, the less the impact of climatic conditions, and low power consumption, but that the disadvantages of high cost of basic facilities and the difficulty in the cost of maintenance, with the lack of flexibility of the pressing demands, and time-consuming in the organization of railroad cars. As for the transfer of land, he has the advantages of investment funds cheaper, and ease of access is high, and the mobility and availability. On the other hand, Disadvantages, low capacity, low and safety, and slow. The advantages of pipeline transportation of high capacity, less the impact of climatic conditions, and cheaper the process of drawing, and the continuation of the means of transport; disadvantages of costly infrastructure and the difficulty of control, goods, specialization, and needs regular maintenance.
The excessive use of road transport also brings many problems, such as traffic congestion, pollution and traffic accidents. In the future, to improve road transport in the transport efficiency and reliability, a revolution in the field of transport policy and management is required, for example, pricing.

Package carriers
