This is a specific timeline of Air Cargo and Airmail history, and a list of more detailed air cargo and airmail timelines. The timelines are also based on (and of course partly overlapping with) the timeline of aviation, but focus specifically on the transport of cargo or freight within air transport as an overall mode of transport. All texts in the diagram are clickable links to other Wikipedia articles, where further information and references can be found.
A few historical developments are reflected in the timeline:
Although airmail has a special legal and regulatory status under postal frameworks [1] [2] - governed by Universal Postal Union (UPU) regulations for postal operators and designated postal carriers - it is typically treated today as a subset of air cargo, which refers to all property transported by aircraft (excluding baggage). [3] [4] In the early decades of aviation, the carriage of mail was one of the primary drivers of air transport infrastructure, aircraft development, and contracted air services. [5] [6] However, from the late 1960's, growth in non-postal freight (parcels, industrial goods, supplies) increased rapidly, aided by larger aircraft and extended route networks, reducing the dominance of mail in overall air freight volumes and value. [7] [8] In the early 21st century, the boom in e-commerce and express parcel delivery has driven strong growth in small parcels and mail-like shipments, which has further blurred the distinction between traditional postal mail and commercial air freight parcels. [9] [10] [11]
Civil and military air cargo operations have historically influenced one another in a reciprocal manner. Technological advancements and innovations originating in military contexts—particularly during periods of conflict—have frequently been adapted for civilian use. Conversely, developments in civil aviation and logistics often serve as foundational technologies for subsequent military applications. This is also applicable for the domains of aviation, logistics and air cargo, where shared infrastructure, dual-use technologies, and evolving operational practices reflect the ongoing exchange between civil and military sectors. [12] [13] [14]
Being relatively young interconnected industries, the aviation, airline, airmail and air cargo industries needed the largest part of the 20th century time to land in a more mature legal and business representation structure after pioneering through successes but also through a number of incidents, scandals and failures. [15] [16] [17] [18] [19] [20] [21] The main milestones of this development can be found in the timeline.

The history of civil airfreight up to the Second World War is essentially one of airmail.
By 1931 85% of airline revenue was from domestic airmail contracts, with 14.8% from passenger service and only 0.2% from freight.
