How much more expensive is air freight than sea freight?

Typically 4–8× more expensive per kilogram. The gap widens for heavy cargo and narrows for small shipments where sea LCL minimum charges reduce the advantage.

What is chargeable weight in air freight?

The higher of actual weight (kg) or volumetric weight (CBM × 167). Light, bulky cargo pays volumetric; dense, heavy cargo pays actual.

How long does sea freight take vs air?

Sea is 14–35 days port-to-port plus customs and inland delivery. Air is 2–6 days door-to-door. Total difference is typically 3–6 weeks.

Is sea freight always greener than air?

Yes — sea emits roughly 50–80× less CO₂ per tonne-km than air freight.

Can dangerous goods go by air?

Some can with IATA DGR compliance. Many goods that ship by sea legally cannot fly at all.

At what size does FCL beat LCL?

Generally above 15 CBM or 10 tonnes. Below that, LCL is usually more economical.
