Air cargo demonstrates resilience amid mixed market signals

Cargo is unloaded from a Korean Air Lines Co freight plane arriving from China at the company's cargo terminal at Incheon International Airport in South Korea. Shipping by air is a fast and efficient means of transport for goods. Airlines transport in excess of 52mn metric tonnes of goods a year, representing more than 35% of global trade by value but less than 1% of world trade by volume, according to IATA, the global body of airlines.
