Choosing between air freight and ocean freight isn’t just about speed. It’s a balance of budget, timelines, cargo type, and risk tolerance. If you're shipping internationally, knowing the true cost breakdown between these two freight methods is key to building a supply chain that works.
This guide will walk you through the cost structures, technical considerations, and strategic use cases for air and ocean freight.
Global Freight Statistics: Air vs Ocean
- Ocean freight handles ~90% of global trade by volume
- Ocean freight accounts for ~70–80% of global trade by value
- Air freight represents less than 1% of global trade volume
- Air freight carries over 35% of global trade by value

Air Freight vs Ocean Freight Costs: Quick Comparison
| Factor | Air Freight | Ocean Freight |
|---|---|---|
| Transit Time | 1–7 days | 12–40+ days |
| Cost per kg (approx.) | $4–$12+ | <$1.50 (LCL); lower for FCL |
| Cargo Type | Time-sensitive, high-value | Bulky, non-urgent, heavy |
| Carbon Footprint | High (avg. 500g CO₂/ton-km) | Low (avg. 10g CO₂/ton-km) |
| Capacity Limits | Strict (dimensional weight applies) | Much higher capacity |
| Reliability | High schedule reliability | Subject to port congestion, weather |
Cost Breakdown: Air Freight
Air freight charges are based on either the actual weight or dimensional (volumetric) weight, whichever is greater. The formula used globally for dimensional weight is:(Length x Width x Height in cm) / 6000 = Volumetric Weight in kg
Airlines also apply fuel surcharges, security fees, and sometimes peak season adjustments. For many trade lanes, expect a price range of $4 to $12 per kilogram, depending on volatility and available capacity.Costs are examples and subject to change.
Cost Breakdown: Ocean Freight
Ocean freight pricing depends on whether you're shipping FCL (Full Container Load) or LCL (Less than Container Load):- FCL: Flat rate per container (e.g., 20’, 40’, 40’ HC)
- LCL: Priced per CBM or per 1000 kg, whichever is greater
Costs are examples and subject to change.
When Air Freight Makes Financial Sense
- Reducing stockouts or avoiding lost sales
- Just-in-time production or tight replenishment cycles
- Urgent warranty or repair shipments
- Short shelf-life products (pharma, perishables, seasonal goods)
When Ocean Freight is the Smarter Play
- Shipping high-volume, low-margin inventory
- Forecasted demand allows 30+ day lead times
- Bulky or dense cargo that’s costly by air
- Heavy items or raw materials
