Critical Air Freight

Critical air freight is a shipment that must arrive by a specific time because a late arrival would cause serious losses. Examples include parts for a stopped production line, components for a grounded aircraft, medical devices for a scheduled procedure and materials for a contract deadline. Critical freight gets a dedicated plan rather than standard routing: a priority booking, a backup option and close monitoring. The term describes the consequence of delay more than the freight itself, so the same item can be routine one day and critical the next.

Next flight out is a service that books freight on the first scheduled flight with available space between two airports. Trucks collect the freight and deliver it to the airline before the cutoff, then recover it at the destination and deliver it. It is one of the fastest scheduled options and costs far less than chartering an aircraft. The trade-off is that it depends on airline schedules, cutoffs and space. When flights are full or no departure meets the deadline, a charter or hand carry may be needed instead.

Counter-to-counter is an air freight service where a shipment is dropped at an airline's cargo counter at one airport and collected at the counter at the destination airport. It usually uses passenger flights, which depart frequently, so small, urgent boxes can move the same day. The shipper or a courier handles the drive to and from each airport. Size and weight limits are tighter than for standard air freight, because the freight rides in passenger aircraft holds. It suits small parts, documents and samples on tight deadlines.

An onboard courier, also called a hand carrier, is a person who travels with a shipment on a scheduled passenger flight and delivers it in person. The item goes as baggage or carry-on, so it stays in the courier's custody the whole way. It suits small, valuable or critical items such as an electronic component, a medical device or legal documents. Onboard couriers skip cargo cutoffs and terminal handling, which often makes them the fastest option for small pieces. Airline baggage rules limit size and weight.

AOG stands for aircraft on ground. It means an aircraft cannot fly until a part is replaced or a repair is made. An AOG is costly for an airline or operator, because the aircraft earns nothing while grounded and schedules may need to change. AOG shipments are therefore among the most time-critical freight. The part may travel by hand carry, next flight out or charter, depending on its size and the distance. Operators often keep AOG desks that work around the clock to source and ship parts.

Belly cargo is freight carried in the lower holds of passenger aircraft, beneath the cabin. Because passenger flights are frequent, belly cargo offers many departures and connections, which helps urgent shipments. Its limits are piece size and height, which must fit the hold doors and space, and security rules that require screening and known shipper status. Larger or restricted freight, such as some dangerous goods, may need a freighter instead. Many urgent shipments fly as belly cargo on the first suitable passenger flight.

An Indirect Air Carrier, or IAC, is a company approved by the Transportation Security Administration to tender cargo to passenger airlines. Freight forwarders and some brokers hold this approval. An IAC must follow a TSA security program covering how it accepts cargo, verifies shippers and handles screening. The program protects passenger flights, which carry a large share of air cargo. For shippers, working with a company that can tender to passenger airlines opens more flights, which can be decisive for critical freight.

Chain of custody is the documented record of who had control of a shipment at each stage, from pickup to delivery. It includes signatures or scans at each handoff: the pickup driver, the airline terminal, screening, the aircraft, recovery and the delivery driver. A clear chain of custody helps prevent loss and tampering and shows where a problem occurred if one does. For critical and high-value freight, shippers often choose options that reduce handoffs, such as hand carry or an exclusive-use vehicle, to keep the chain short.

A full charter books an entire aircraft for one shipper, who decides the departure time and route. A part charter shares an aircraft between two or more shippers who split the cost, usually on a route that suits all of them. Part charters can cost less, but the shipper gives up some control over timing and may wait while the aircraft is filled. For truly critical freight, a full charter offers the most control. A part charter can make sense when several shipments are heading the same way.

Exclusive-use ground transport means one shipper reserves an entire van or truck for its shipment. The vehicle goes straight from pickup to delivery without stops for other freight or transfers through terminals. It is often used for critical freight on shorter lanes, where driving door to door beats the time spent on airport cutoffs and handling. It also suits freight that cannot fly, such as some hazardous materials, or freight that is ready too late in the day to make any flight.

Many lithium batteries can ship by air when they meet the rules for packaging, state of charge, marking and documentation. Some lithium battery shipments are restricted to cargo aircraft only, which limits the flights available. Rules differ for batteries shipped on their own, packed with equipment or contained in equipment. In the United States, the hazardous materials regulations apply, and airlines also follow IATA rules. Shippers should declare lithium batteries and share the safety data sheet when requesting a quote, so the right flight can be booked.
