Air Mobility Command uses hub and spoke operations to move a significant portion of cargo around the world as efficiently as possible. However, additional efficiencies afforded through hub and spoke delivery come at the cost of longer delivery times and greater delivery time variations. Leaders require an expanded understanding of those costs to make informed decisions with respect to Air Mobility Command operations. This study examines the relationship between port hold time and total time enroute, the division of port hold time attributable to port tasks and command and control functions, and potential causes for port hold time variations. It was completed in response to ancillary findings of high correlation between port hold time and total time enroute at Incirlik Air Base AB, Turkey in a previous study. Using regression analysis and descriptive statistics, this study verifies the correlation between port hold time and total time enroute, characterizes the portion of port hold time attributable to port processing and cargo awaiting lift functions, explores the relationship between port hold time and logical causes of variation, and makes leadership recommendations to improve AMCs delivery performance and customer satisfaction.
