Air Shipping Services

Air shipping services move goods by aircraft, from small parcels to full planeloads of freight. The main options are air express for parcels and documents, air freight on scheduled flights for palletized cargo, deferred air for shipments with flexible dates, hand carry for small critical items, and air charter for freight that needs a whole aircraft. Most shippers use them door to door, with trucks handling pickup and final delivery. The right service depends on the size and weight of the shipment, how soon it must arrive, and whether it can travel on a passenger aircraft or needs a cargo plane.

Air express is built for parcels and documents. It moves through a parcel network with set size and weight limits and fixed schedules, and it is priced per package. Air freight is built for larger shipments, such as pallets, crates and machinery, that exceed parcel limits. It flies in the cargo holds of passenger aircraft or on freighters and is priced on chargeable weight. Air freight usually involves more handling at airline terminals, so trucks deliver the freight to the airline before a cutoff and recover it at the destination airport.

Consolidated air freight combines shipments from several shippers into one larger load that a forwarder books with an airline. Because the forwarder buys space in bulk, each shipper usually pays less than booking alone. The trade-off is time. Freight waits until the consolidation is built, then is broken down and sorted at the destination before final delivery. Consolidation suits freight with some slack in the schedule. Urgent shipments are usually booked individually on a priority basis, such as next flight out, so they do not wait for other freight.

Deferred air freight is a lower-cost service where the shipment flies when space is available rather than on a guaranteed flight. Airlines and forwarders use it to fill spare capacity, so the shipper gets a lower rate in exchange for a less certain delivery date. It is still much faster than ocean freight across long distances. Deferred service suits restocking, planned replenishment and other shipments that can arrive a few days later without causing problems. It is the wrong choice for anything tied to a production line, an installation date or a customer deadline.

Dimensional weight estimates how much an air shipment weighs based on the space it takes up. Measure the length, width and height at the longest points, including the pallet, and multiply them together. For US domestic air freight measured in inches, divide the result by 166 to get dimensional weight in pounds. International shipments often use metric measurements and a divisor of 6,000 cubic centimeters per kilogram. The carrier then bills the higher of dimensional weight and actual weight. Accurate measurements matter, because carriers remeasure freight and correct the charge when the numbers are wrong.

Chargeable weight is the weight used to price an air shipment. It is the greater of the actual weight on a scale and the dimensional weight calculated from the shipment's size. The rule exists because aircraft run out of space as often as they run out of weight capacity. A light but bulky shipment uses space that could carry heavier freight, so it is charged by its dimensions. A small, dense shipment is charged by what it weighs. Compact packaging and tight palletizing can lower chargeable weight for bulky goods.

Some dangerous goods are forbidden on all aircraft, and others can only fly on cargo aircraft, not passenger planes. Many more can fly when properly classified, packed, marked, labeled and declared. Items that commonly need special handling include lithium batteries, aerosols, flammable liquids such as paints and solvents, compressed gases, dry ice and magnetized materials. In the United States, the hazardous materials regulations in 49 CFR apply, and most airlines follow the IATA Dangerous Goods Regulations. The airline or operator decides whether to accept a shipment, so shippers should check before tendering.

Ocean freight is far cheaper per pound, which is why most of the world's goods by weight travel by sea. Air freight costs more but moves in hours or days instead of weeks. The comparison changes when time has a cost. Goods held at sea tie up inventory, and a missed delivery date can stop production or lose a sale. High-value items, urgent parts and seasonal goods often fly even though the freight bill is higher. For shipments within North America, the realistic alternative to air is usually a truck rather than a ship.

An air waybill is the shipping document that travels with an air freight shipment. It acts as the contract of carriage between the shipper and the airline and as the receipt for the goods. It lists the shipper, consignee, origin and destination airports, number of pieces, weight, dimensions and a description of the contents, along with any special handling. Each air waybill carries a unique number used to track the shipment. It is not a document of title, so it cannot be used to transfer ownership of the goods the way some ocean bills of lading can.

A hand carry or onboard courier service sends a person with the shipment on a scheduled passenger flight. The courier checks the item as baggage or carries it on, travels with it, and delivers it in person at the destination. The item never leaves the courier's custody, which suits small, valuable or critical parts such as a circuit board, a medical device or legal documents. Hand carry is limited by airline baggage rules and what one person can manage. It is often faster than freight because it skips cargo cutoffs and terminal handling.

Freight for air should be packed to survive several handoffs between trucks, terminals and aircraft. Use sturdy cartons or crates, fill empty space so contents cannot shift, and protect corners and fragile parts. Palletized freight should sit fully on the pallet with no overhang and be strapped or shrink-wrapped as one unit. Mark pieces that cannot be stacked, and add orientation arrows when the freight must stay upright. Label every piece with shipper and consignee details. Packing compactly also helps cost, because bulky packaging raises dimensional weight even when the goods inside are light.
