Basic Principles of Air Cargo Transport

The standards for carrying cargo by air are laid down by ICAO, IATA, and (in India) the DGCA. The facilitation framework lives in Annex 9 (“Facilitation”) to the Chicago Convention — its Standards and Recommended Practices govern the international and domestic carriage of cargo, passengers, and crew. States may deviate, but must notify ICAO, and the differences are published in a supplement to Annex 9.

Acceptance hinges on condition and documentation: cargo must be properly packed, labelled, and weighed, clean enough not to contaminate the hold (no dirty pallets, wet cargo, or soiled tarpaulins), handled per its type — dangerous goods, human remains, and live animals each follow distinct procedures — and accompanied by complete, correct documentation. Insufficient packing and improper marking remain leading causes of cargo loss, which means the shipper holds real power over a shipment’s safe arrival.

Advantages, Limits & the Load Equation

How much an aircraft can actually accept is an equation of many variables:

Governing Bodies & the IATA Cargo Agent

IATA’s organs — the General Assembly, Executive Committee, and Secretariat (Montreal and Geneva) — pursue cooperative information exchange, standardised cargo rates and rules, and simplified inter-airline settlement. ICAO, the UN’s aviation agency under the 1944 Chicago Convention, regulates airspace, aircraft, crew, and all civil air operations. Between airline and shipper stands the IATA Cargo Agent — the accredited forwarder who mediates the transport and represents the shipper. The agent’s duties: tender goods “Ready for Carriage,” obey IATA rules, and settle all freight charges claimed on behalf of airlines on time — violations can cost the agency itself. Notably, accreditation is advantageous but not mandatory for handling air cargo.

Rates, Rules & Accessorial Charges

The Air Waybill (AWB) anchors acceptance — it is the contract of carriage itself. Dangerous goods move only under ICAO/DGCA regulations, and tariffs apply from origin to destination through a three-tier rate logic:

Priority fine print worth memorising: a priority request is not a reservation and guarantees no specific flight; the shipper writes “priority,” flight number, and gate on the AWB; and if the carrier misses the wished flight, the shipment stays priority unless the shipper says otherwise. On top of line-haul rates ride the accessorial charges — fees for services beyond transport: AWB preparation, AES export filing, change of AWB (CCA), cold and dry storage, consolidation, palletising/de-palletising, dangerous goods fees by class, fuel surcharge on chargeable weight, import service charge, oversize fees, peak-season and security fees, and ULD demurrage, among others.

Environmental Hazards: The Physics of the Journey

Hazards continue on the ground. In terminals, conveyor systems and mechanical gear speed movement, but poorly equipped facilities invite robbery, pilferage, and value loss — perishables belong in reefer storage, dangerous goods in trained hands per ICAO/IATA instruction. On trucks, cargo must be packed to withstand stacking up to 8 feet, pressure from adjacent freight, tie-down strap crush, manual handling, and weather — palletise, unitise, containerise, and keep water-protective coverings with the load for the whole journey. Liquid cargo should never be filled to the brim (leave expansion space for temperature and pressure swings), with seals, valves, and caps firmly closed and clear external markings. Large, heavy, or awkward pieces demand checks on permissible floor-weight concentrations, skids for mechanical handling, and dimensions that clear the loading doors.

Containerization: Four Families of ULD

Carriers love containerised freight — fewer individual pieces to handle, fuller use of aircraft volume, maximum advantage from mechanical systems, faster turnarounds, and less exposure to weather, theft, and handling damage. Forwarders consolidating mixed goods ship under FAK (“Freight-All-Kinds”) tariffs, though carriers may exclude certain items (including IATA dangerous goods) from FAK rates.

CUDCT: India’s Common User Cargo Terminals

The Airports Authority of India, constituted on 1 April 1995 under the AAI Act 1994, has managed cargo terminals for decades — handling international cargo at Delhi, Mumbai, Chennai, and Kolkata until Joint Venture Companies (DIAL, MIAL) took over Delhi and Mumbai in 2006. AAI then pushed into Common User Domestic Cargo Terminals, starting at Kolkata (2008) and Port Blair (2010), while running international terminals at Kolkata, Chennai, Amritsar, Lucknow, Guwahati, Coimbatore, Trichy, and Mangalore. The “common user” idea is simple and powerful: one shared, professionally run terminal open to all airlines and forwarders — forward integration that brings organised air cargo to far-flung regions. (AAI’s dedicated cargo subsidiary, AAICLAS, now carries this mandate.) The bet has aged well: air cargo today moves over US$8 trillion of goods — about 33% of world trade by value (IATA), and Boeing projects India’s domestic air cargo market to nearly quadruple as express and e-commerce networks expand.
