Air Freight

Air freight is the commercial transportation of goods by air, typically for international or time-critical shipments. It is the fastest mode of freight transport available for most global trade lanes, enabling door-to-door delivery across continents in days rather than weeks.

How Air Freight Works

Air freight typically moves through a chain of service providers:

1. Freight forwarder: The shipper books with a forwarder (DHL Global Forwarding, Kuehne+Nagel, Flexport) who consolidates cargo and negotiates rates with airlines
2. Origin handling: Cargo is trucked to an airport cargo terminal, weighed, measured, and screened per TSA/security requirements
3. Air transport: Cargo travels in the aircraft hold (belly) or on dedicated freighters
4. Customs clearance: At destination, the forwarder or customs broker handles import declarations, duties, and taxes
5. Last-mile delivery: Cargo is deconsolidated and delivered by truck or courier

For express shipments (FedEx, UPS, DHL Express), steps 1–5 are handled by the integrator as a single service.

When to Use Air Freight

Air freight is justified when:

• The shipment has a high value-to-weight ratio (electronics, pharmaceuticals, jewelry)
• Delivery time is critical (just-in-time components, perishable foods)
• Ocean freight lead times would create stockouts
• Emergency replenishment is required mid-season

Air Freight Rates and Pricing

Air freight rates are typically quoted in dollars per kilogram and charged on chargeable weight (the greater of actual weight vs. dimensional weight). Rates vary significantly by trade lane, season, and market conditions.

Key cost components:

• Base rate (per kg)
• Fuel surcharge (variable, indexed to jet fuel prices)
• Security surcharge (per kg or per shipment)
• Handling fees at origin and destination
• Customs brokerage fees

Air Freight vs. Express Courier

Air freight and express courier services are related but distinct. Air freight is typically used for larger shipments (100 kg or more), involves multiple parties (forwarder, airline, broker), and requires more manual coordination. Express services like FedEx International Priority or DHL Express handle smaller shipments end-to-end with integrated tracking and guaranteed delivery windows.

For e-commerce, express courier dominates. For B2B industrial or retail replenishment, air freight forwarding is more common.
