This study aims to analyze empirically the transport patterns and correlations of major import and export commodities in air cargo. From 2000 to 2019, we analyzed air cargo panel data by export and import, amount and weight for four major commodities, electronics, machinery, chemical industry, and agricultural products for the top 126 countries. The gravity model was adopted and we analyzed it using explanatory variables GDP, per capita GDP, distance between capitals, land area of trading partners, landlocked countries, FTA agreements, and Cargo Open Skies agreements(COSA). The results of the analysis model show that GDP is significant for household goods, steel and metal products, and machinery and electronic products. GDP per capita shows valid results for all items, and FTA shows limited meaningful results in agricultural and fishery products, minerals, plastics, rubber and leather products, textiles, steel and metal products, and machinery and electronic products. The Cargo Open Skies agreements also shows valid only for agricultural and fishery products and household goods. It was found that the frequency of the major factors of air freight was affected in order of GDP per capita, FTA, GDP, and COSA.

The volume of air mail is being reshaped mainly for B2B and B2C goods or parcels in accordance with the development of e-Commerce. This study aims to analyze the international network of air mail growing into the transport route of e-Commerce and to present its development direction. Therefore, we analyzed 3 centralities (degree centrality, closeness centrality, betweenness centrality) of air mail networks from 2014 to 2018 for the top 100 cities of mail traffic volume through Social Network Analysis (SNA) methodology. As a result of analysis, Frankfurt (Germany), London (United Kindom), Istanbul (Turkey), Amsterdam (Netherland) in Europe occupies an absolute position in 3 centralities, and Hong Kong, Seoul (Republic of Korea), Tokyo (Japan), Bangkok (Thailand) occupies has high position. Incheon International Airport is not only one of the major hubs on the air mail route, but also has high scores on various network indexes. It seems to be favorable for accessing a wide range of e-Commerce markets such as China, Japan, and the United States.
