Air Freight Shippers

Air freight is shipped by businesses whose goods are valuable, urgent or both. Aerospace companies ship parts for grounded aircraft. Automotive and manufacturing plants ship parts to keep production lines running. Medical device makers, electronics and technology companies, trade show exhibitors and energy and construction firms are also regular air freight shippers. Retailers and e-commerce sellers use air for fast-moving or seasonal goods. What they share is a situation where the cost of a late or damaged shipment is higher than the cost of flying it.

Air freight costs more per pound than truck or ocean freight. Aircraft doors and decks limit how large and heavy a single piece can be. Flights have tender cutoffs, and missing one can mean waiting for the next departure. Weather, airport congestion and missed connections can cause delays, and each airport handoff adds a step where something can go wrong. Some dangerous goods are restricted or forbidden. Air also produces more emissions per pound than ground transport. For many shipments, these trade-offs are worth it, but they are why air works best for urgent or high-value freight.

A known shipper is a business whose identity and legitimacy have been verified under the Transportation Security Administration's air cargo security program. Cargo from a known shipper can be accepted for transport on passenger aircraft, subject to screening rules. Cargo from an unknown shipper is generally limited to all-cargo aircraft. Known shipper status is managed by the airlines and the companies that tender cargo to them. For shippers, it matters because passenger flights offer far more departures than freighters, which can mean faster delivery.

Chargeable weight is the weight an air shipment is billed on. It is the greater of the actual weight on a scale and the dimensional weight, which is based on the space the freight takes up. For US domestic air freight measured in inches and pounds, dimensional weight is commonly length times width times height divided by 166. Light, bulky freight is charged by its dimensions, while dense freight is charged by actual weight. Compact packaging and accurate measurements help shippers keep chargeable weight, and the final bill, under control.

Airport-to-airport service covers only the flight. The shipper must deliver the freight to the airline's cargo terminal before the cutoff, and the consignee must collect it at the destination airport. Door-to-door service adds trucks for pickup at the shipper's dock and delivery to the consignee. Door-to-door is simpler for most businesses and puts one party in charge of the handoffs. When comparing quotes, check which service is included, because the truck legs can take a large share of the total time.

A tender cutoff is the latest time freight can be delivered to the airline's cargo terminal and still make a particular flight. Cutoffs allow time for acceptance, screening, building pallets and loading the aircraft. They are usually some hours before departure and vary by airline, airport and flight. Freight that arrives after the cutoff waits for a later flight, which can push delivery back by a day. Shippers can help by confirming a realistic ready time so pickup and the drive to the airport fit within the cutoff.

An air freight carrier is an airline or charter operator that flies the aircraft. A freight forwarder books space with carriers, often consolidates several shippers' freight, and handles international documents. An air freight broker arranges a specific shipment on the shipper's behalf, choosing the flight or charter and booking the trucks at both ends, usually with one contact managing the whole move. Shippers with urgent domestic freight often use a broker, while international importers and exporters often use a forwarder.

Many dangerous goods can ship by air when they are properly classified, packed, marked, labeled and declared. Some are forbidden on all aircraft, and others are allowed only on cargo aircraft. In the United States, the hazardous materials regulations apply, and most airlines also follow the IATA Dangerous Goods Regulations. Common items that need care include lithium batteries, aerosols, paints, adhesives, compressed gases and dry ice. Shippers should share the safety data sheet when asking for a quote, so the shipment can be booked on an aircraft that accepts it.

An air waybill is the shipping document for air freight. It serves as the contract between the shipper and the airline and as the receipt for the goods. It lists the shipper and consignee, the airports, the number of pieces, weight, dimensions and a description of the goods, along with any special handling instructions. Each air waybill has a unique number used to track the shipment. Unlike some ocean bills of lading, it is not a document of title and cannot be used to transfer ownership of the goods.

No, but many do. Freighters operated by express and parcel networks often fly overnight so packages collected in the evening can be sorted at a hub and delivered the next morning. Airports also tend to have more capacity at night. Cargo also flies all day in the holds of passenger aircraft, which follow passenger schedules. Charter flights depart whenever the freight and aircraft are ready. For urgent freight, the ability to use daytime passenger flights as well as overnight freighters gives shippers more options.

Air freight tracking follows status events tied to the air waybill number. Typical events include acceptance at the cargo terminal, departure, arrival at the destination airport and availability for pickup. Door-to-door shipments add truck pickup and final delivery events. Airlines post these updates to their systems, but the level of detail varies by carrier. Many shippers prefer a single contact who watches the events and calls when something changes, rather than checking several airline systems themselves. Proof of delivery confirms who received the shipment and when.
