Forecasting for air demand such as passengers and freight has been one of the main interests for air industries. This research has mainly focus on the comparison the performance between the univariate seasonal ARIMA models and the multivariate time series models. In this paper, we used real data to predict demand on international passenger and freight. And multivariate time series models are better than the univariate models based on the accuracy criteria.

According to globalization of world economy on distribution and sales, logistics and transportation parts are play important role. Especially, it important to know and study how to choose right transport route and which is the key factor of route choice model in multimodal transport system. Thus this study aims to consider 4 main factors: cost, delivery time, freight, and logistics service factors additionally dividing into 13 sub factors and object is forwarders between Mongolia and Korean freight transport. The survey is based on AHP through interview with company officials. The paper provides empirical insights about current status of Mongolian forwarders and difference of the important factors between transportation modes. Result shows that time factor is role factor to choose transport route and then cost factors. Additionally, this study shows 2 different route choose factors between air transport and shipping transport forwarders.

The aviation demand forecast field has been actively studied along with the recent growth of the aviation market. In this study, the demand for domestic passenger demand and freight demand was estimated through cross-validation method. As a result, passenger demand is influenced by private consumption growth rate, oil price, and exchange rate. Freight demand is affected by GDP per capita, private consumption growth rate, and oil price. In particular, passenger demand is characterized by temporary external shocks, and freight demand is more affected by economic variables than temporary shocks.

This study empirically analyzed air transport trade patterns using data for 30 years between Korea and its trading partners in order to identify specific factors that determine the size of Korea's air transport trade. Independent variables were GDP per capita, capital distance between countries, country area data and number of airports. In addition, it reflected whether it is a landlocked country and whether it has joined the OECD, APEC and ASEAN+3. According to the results of the analysis, it was found that the air cargo trade pattern in Korea is proportional to GDP per capita, and the scale increases as the distance is closer. In addition, the national area and the airport capital acted as a factor in increasing air transport trade. However, whether a country is a landlocked country did not show significant results in terms of trade, exports, and imports. The OECD, APEC, and ASEAN+3 variables were found to generally increase air transport trade.

Commerce enriches human life enriched and within commerce, transportation of cargo is arguably the most important in business transactions. Traditionally, marine transport has been major commercial transaction, but carriage cargo by air is on the increase. While the fare for freight in comparison with that of ocean is higher, air freight has many benefits that justify the higher shipping fee; lower insurance premium, packing charges, inventory control, cost management and especially speed. Therefore, air freight transport is accumulating gradually. An air waybill(AWB) is needed in the air transport flow. It is a nonnegotiable security, so the holder cannot transfer of a right to a third party. Some scholars suggest that a negotiable AWB is needed. However, it seems nearly impossible to do so; an e-AWB use shows a gain in numbers, even if it has not met expectations. Going forward, it would appear reasonable to conduct a follow-up study on the utility and legal problem for e-AWB. After sending goods, the consignor has the right of disposition of cargo in some cases, and more research is necessary, because it is related to change of ownership and a trade settlement. According to WATS (World Airlines Transport Statistics), the Korean Air took third place in international freight in 2014, and fifth in total, domestic and international to great acclaim. However, there is a lack of research supporting the business showing. It is hope that more studies on e-AWB, stoppage in transit, and a risk of outstanding amount, etc. connect to develop Korean air freight industry.

This research explores the relative importance of factors and service items that influence the air cargo service quality for provision services by the Skyteam Cargo in the Korean market. In general, the Skyteam Cargo provides a package of services which are different functions and operations of service such item as Equation Heavy (heavy and large express freight), Equation (small express freight), Variation (special freight), and Dimension (general freight). To carry out the research, the expert questionnaire survey, the Analytic Hierarchy Process (AHP) analysis had adopted to evaluate the level of quality for the provision air cargo operation services by the Skyteam Cargo at Incheon International Airport. Based on an expert survey and the AHP, five core service factors, namely, infrastructure as installed facilities, reliability, promptness, efficiency, and safety are defined.

Increasement of total cost during distribution chain requires packaging standardization to reduce extra handling and delays at transshipment point. In Korea, high valued agricultural products to export are most often shipped by air freight. Fresh flowers, in particular, the need to set package standard for air palletization are strongly recommended. This study tried to find an optimum standard dimensions for export packages. After extensive research on combinations of various flower dimensions, package dimensions and pallet sizes, we found that 96 inches pallet was most adequate for international air freight. Based on the results, new 40 standard package dimensions were introduced and stacking efficiencies were calculated.

Global warming has become one of the most important social responsibilities. After Kyoto protocol for greenhouse gas reduction by climatic change convention came into effect, developed countries are presenting various policies to reduce greenhouse gas that is produced in transport field. One of those policies is modal shift that change from road freight to sea, inland waterway and railway transportation that is eco-friendly. Because increase of road freight brings about road congestion and accident, logistics cost, air pollution and green house gases. Railways are superior to all other modes of transport in mass transportability, high speed, timeliness, safety and environmental-friendliness, but the railway industry has been pushed behind in competition. In developed country's government actively promoted relevant legislation, policies, and countermeasures known as modal shift policies to shift freight transport from road to large volume mode such as railway and ship. In this paper, we discuss the current situation in modal shift, compare it with cases in other countries EU and Japan, identify problems in Korea, and propose the following ways to enhance competitiveness of rail freight.
