The potential of horizontal collaboration in airport ground freight services

• A conceptual framework for transport collaboration in air cargo industry is proposed.
• A simulation model is used to analyze the collaboration within Schiphol airport.
• Horizontal cargo transport collaboration improves transport performance.
• A high frequency of transport movements can be maintained at lower costs.
• Transport collaboration reduces transport costs of air cargo within airport by 40%.

Since the global economic crisis of 2007–2011, the increasingly dynamic and challenging air cargo market in Europe has forced freight forwarders to improve their performance. In addition to improving their internal transport efficiency, they have also started to look at previously unexplored opportunities for horizontal collaboration in landside airport transport. The aim of this study is to reveal the potential of air cargo transport collaboration on a horizontal level, i.e. between multiple freight forwarders within a single airport. Reviewing existing literature on horizontal collaboration, with a focus on the air cargo industry, we propose a conceptual framework for transport collaboration in the air cargo industry. Based on a comprehensive study on air cargo transport movements within Schiphol, using a simulation model based on company data of 10,747 shipments (6977 tons of cargo) for a period of 30 days, we find several interesting results. Our main finding is that horizontal collaboration can improve the transport performance, by maintaining a high frequency of transport movements and maintaining an acceptable throughput time for air cargo shipments, and at the same time reduce transport costs by up to 40%. For smaller freight forwarders, the frequency of transport deliveries can even increase, while still allowing them to improve the average load factor of transport movements.
