International air cargo growth continues to be highly reliant on cross border e-commerce traffic originating from China. We estimate that about 35% of international air cargo currently consists of express small package and cross border e-commerce consolidations – up from about 26% five years ago. Future air cargo growth expectations continue to ride on cross-border e-commerce rather than traditional global supply chain traffic. We forecast international air cargo growth of between 2.8% and 5.5% for the next five years. This article discusses growth drivers and downside risks.
