This document provides a historical overview of air freight logistics. It discusses how air cargo began in 1910 with mail delivery flights. It then covers the development of overnight express services by Federal Express in the 1970s using a hub and spoke system. The arrival of widebody jets in the 1970s increased cargo capacity but also provided low-cost capacity for passenger airlines. The document outlines the different types of air cargo carriers and concludes with predictions that economic growth and globalization will continue to support future air cargo growth, though air mail is declining as a portion of airline revenue. Integrated carriers focusing on customer service have seen the most success over combination carriers.
