The Value Of Air Cargo
IATA article https://www.iata.org/en/programs/cargo/
Enabling global trade
Airlines transport over 52 million metric tons of goods a year, representing more than 35% of global trade by value but less than 1% of world trade by volume. That is equivalent to $6.8 trillion worth of goods annually, or $18.6 billion worth of goods every day.
Since the COVID-19 crisis began, air cargo has been a vital partner in delivering much-needed medicines, medical equipment (including spare parts/repair components), and in keeping global supply chains functioning for the most time-sensitive materials. This has been done through dedicated cargo freighter operations, utilization of cargo capacity in passenger aircraft, and relief flights to affected areas.
