Your first international shipping venture can feel overwhelming, especially when deciding between air freight and ocean freight.
Many beginner business owners are unsure how these two options differ in terms of speed, cost, reliability, and environmental impact. That’s why we’ve created this guide, to clearly explain how each shipping method works, along with their pros and cons.
We’ll also break down air freight vs. ocean freight costs, explore when to choose either option (or both), and show how a trusted logistics company can help you make the right decision. Finally, we’ll answer a few common questions you might have along the way.
What Is Air Freight?
Air freight is the process of shipping goods internationally via an air carrier. It’s a fast shipping method, reliable in delivering time-sensitive cargo like perishable goods (food, drink, or pharmaceuticals), urgent products, or items with high value.
From small to large businesses, air freight gives companies an edge against competitors and helps cement their market standing.
However, its enhanced dependability and speed make it an expensive choice.
How Air Freight Shipping Works
The air freight shipping process from start to finish goes as follows:
- Shipment preparation: You first prepare the products you want to ship, packaging them according to air cargo packaging standards. You ensure you write handling instructions and shipping details clearly.
- Booking: Next, companies contact an air freight forwarder, providing necessary shipment specifications like destination, package weight, and more. They also hand over any documentation required by international transportation laws.
- Customs clearance: This documentation is then presented to customs authorities to get clearance for shipping, equally adhering to international trade regulations. Security screening also happens in this stage.
- Transportation of goods: Your packages get to the airport, where they’re loaded using the right procedures into an air carrier and then transported.
- Monitoring shipments: Companies can then track their shipment’s progress via a tracking number provided by the air freight forwarder.
- Arrival at destination: Finally, the shipment reaches its destination airport, where the packages go through customs once more. When cleared, they’re delivered to the shipping address.
Advantages of Air Freight
One eye-opening statistic shows that the global cargo airline industry generated huge revenue in 2021, peaking at 175 billion U.S. dollars. The countless benefits of air freight are what caused those numbers, making it the preferred means of shipping for companies worldwide:
- Helps you meet tight deadlines by being fast without compromising reliability.
- Enables you to reduce inventory holding costs.
- Usually includes premium insurance plans.
- An amazing shipping method for long distances.
- Easily accesses most locations due to its global reach.
- Highly secure to minimize the chances of theft or tampering with cargo.
Disadvantages of Air Freight
Despite its glowing perks, air freight comes with a few drawbacks you need to consider before commitment:
- Much more expensive than ocean freight and other shipping means (road or rail freight).
- It’s subject to weight and size restrictions, making it unsuitable for large, heavy cargo.
- In some cases, customs can cause delays, which affect customer satisfaction, increase storage costs, and mess with schedules.
- More influenced by weather conditions than ocean freight.
- Pricier VAT and duty fees.
What Is Ocean Freight (Sea Freight)?
Alternatively, ocean freight refers to the process of shipping goods using cargo ships. While slower than air freight, it’s great when transporting heavier, bulkier goods in containers.
According to UNCTAD 2025 figures, seaborne shipping transports 80% of all global traded goods by volume. But how does ocean freight shipping work?
How Ocean Freight Shipping Works
The ocean freight shipping process is pretty simple to sum up:
- Packing: The first step involves packing goods according to size, weight, and nature to ensure compliance with global shipping rules.
- Booking containers and cargo ship space: Ocean freight forwarders then book suitable shipping containers as well as the needed space on a shipping vessel.
- Export customs: Your cargo goes through customs for clearance and security screening, which takes place at the port.
- Loading into the ship: Goods are then packed into the shipping containers and then moved onto the ship.
- Arrival at the destination port: After the sea voyage, containers are offloaded. The next step is to go through import customs at the destination port.
- Final delivery: Once they’re cleared, goods are delivered to the final shipping address.
Advantages of Ocean Freight
Wondering what perks sea freight can grant you? Here are some benefits that make it a central part of the global trade:
- A cost-effective option for businesses.
- Perfect for transporting goods in bulk, since cargo ships can handle much more weight than planes.
- The ability to reach remote locations.
- Lower VAT and duty fees.
- Smaller carbon footprint thanks to its huge economies of scale, making it more eco-friendly.
- Less affected by most weather conditions than air freight.
Disadvantages of Ocean Freight
Some downsides to ocean freight are:
- It doesn’t work for time-sensitive shipments.
- Longer delivery times.
- Risks of port congestion, which might lead to delays.
- Prone to reliability issues.
Air Freight vs. Ocean Freight: Key Differences Every Business Owner Should Keep in Mind
For a clearer judgment of air freight vs. ocean freight, understanding the key differences between the two methods is crucial. This section addresses points that set them apart: speed, costs, capacity, reliability, environmental impact, and inventory-related considerations.
Shipping Speed
Shipping speed in air freight is much faster than in ocean freight. For reference, airborne cargo is typically transported within 1–7 days (depending on how far the destination is and the specific route, of course).
On the other hand, seaborne cargo could take weeks or even months to reach its destination port (also based on similar factors).
Cost Comparison
Air freight has higher operational costs, and that’s why it requires a much bigger budget than ocean freight. For example, expenses related to air transport include fuel, labor costs, airport fees, and security.
On average, air freight costs are between $4 to $12 per kilogram.
Ocean freight operational costs are much lower, even covering fuel, port handling charges, customs clearance fees, and the like. If you choose this shipping method, expect to pay around $3,500 for a 40ft container.
Cargo Capacity
Although it might seem surprising, air freight cargo capacity comes with strict limits. Size and weight restrictions vary depending on the type of aircraft.
|
Aircraft type |
Maximum height |
Maximum weight per piece |
|
Narrow-body |
80–110 cm |
Less than 150 kg |
|
Wide-body |
160 cm |
500–1,000 kg |
|
Main deck freighter |
240–300 cm |
1,000–5,000 kg or more |
As for ocean freight, its cargo capacity is based on container size and volume (and it’s higher than in air freight):
|
Container type |
Volume |
Maximum weight allowed |
|
20-foot Standard |
33 m³ |
21,500 kg |
|
40-foot Standard |
67 m³ |
26,500–28,500 kg |
|
40-foot High Cube |
76 m³ |
More than 28,600 kg |
Reliability
Air freight is more reliable than ocean freight when it comes to meeting deadlines and staying on schedule. It’s less subject to delays, whereas ocean freight is prone to port congestion, and seaborne cargo is handled more often than air-shipped cargo.
Environmental Impact
Another crucial factor to take into account is each method’s carbon footprint, and this is where sea freight scores a point, emitting an average of 10g CO2/ton-km.
In contrast, air freight has a significantly higher environmental impact, producing over 500g CO₂ per ton-km.
Inventory Management Considerations
Air freight inventory levels are lower because transit times are significantly shorter. However, ocean freight inventory management considerations are lengthier, with higher warehousing and holding costs.

Air Freight vs. Ocean Freight Costs
As a business owner, especially if it’s a small business, shipping costs make all the difference in determining the shipping method. That’s why it’s a good idea to learn about the various factors that affect both air and sea freight costs.
What Affects Air Freight Costs?
Air freight costs are first influenced by the weight of the cargo. They’re calculated based on whichever is higher: gross weight or dimensional (volumetric) weight. There’s even a global formula for calculating volumetric weight:
Length x Width x Height (in cm) / 6000 = Volumetric Weight (in kg)
Other factors that come into play are:
- Fluctuations in global gas prices
- Distance and route, with often-traveled routes being cheaper and longer distances more expensive.
- Market demand
- Whether the shipping takes place in the peak season
- Cargo type (perishable goods or hazardous materials require specific handling and safety compliance measures, leading to more expenses)
- Custom fees
What Affects Ocean Freight Costs?
The things that affect ocean freight costs are pretty similar to those impacting air freight:
- Cargo size and weight, with larger, bulkier packages costing more
- Shipping mode, which can be either FCL (Full Container Load), requiring a flat rate, or LCL (Less than Container Load), charging by cubic meter or weight.
- Route and distance
- Market demand, fuel prices, and port congestion concerns
- Customs, duties, and global exchange rates
Which Option Is More Cost-Effective?
Ultimately, ocean freight is more cost-effective, as it’s ideal for large-scale cargo transport. However, it’s still susceptible to risks (port congestion and customs delays), so consider these concerns carefully to judge if they’re worth it.
Sure, ocean freight might be cheaper, but schedule delays will also cost you money.
When Should You Choose Air Freight?
Some scenarios when it’s advisable to choose air freight include:
- You need to transport short shelf-life goods (perishable items and pharmaceuticals).
- You’re sending out urgent, time-sensitive shipments.
- The shipment includes items that could disrupt supply chains.
- You’re dealing with Just-In-Time inventory.
- You’re handling warranty or repair shipments.
- You want to access remote locations that’ll be more challenging or time-consuming for ocean freight.
When Should You Choose Ocean Freight?
Ocean freight is the best fit for when:
- You’re shipping high-volume inventory.
- You’re transporting especially heavy items or raw materials.
- You’re shipping bulky cargo that exceeds airline size and weight restrictions.
- You want to maximize your budget for long-haul logistics.
- You have the luxury of a flexible timeline or schedule.
- You’re not shipping urgent, seasonal, or perishable cargo.
- You’re sending or receiving hazardous materials or objects that aren’t permissible on planes (chemicals, fuel, gases, etc.)
Can Businesses Use Both Air and Ocean Freight? (When Both Make Sense)
Yes! In some cases, a hybrid freight method can work best: consider splitting your shipments to reap the benefits of both air freight and ocean freight.
For instance, you can send a small percentage of goods to ensure early arrival if they’re wanted immediately. Then, ship the rest of your non-time-sensitive products by sea.
In these hybrid schemes, you can get both timely delivery for urgent products and reduced costs for shipments that don’t require speed!

FAQs
Is sea freight cheaper than air freight?
Yes. The average cost for ocean freight shipping sits at $3,500 for a 40ft container.
On the other hand, air freight charges $4–$12 per kilogram, which is less cost-effective and unfit for a limited budget.
Why is sea freight cheaper than air freight?
Sea freight has the advantage of being more fuel-efficient. The reason is that the ocean’s buoyancy helps with the heavy weight, which reduces fuel usage.
Plus, the economies of scale rule apply to it. In other words, cargo ships can transport 100x more volume than cargo planes per trip, since they’re prepared to carry many 20ft and 40ft shipping containers.
This way, a logistics company gets to distribute the costs of fuel, labor, and other expenses across a huge number of goods.
Yet, planes have severe weight and size limits. When air freight operational costs (already pricier than those of ocean freight) are divided across a limited number of goods, each item’s shipping costs will be much higher.
Lastly, the processes of offloading and handling cargo in a port are more standardized than in an airport. In airports, these procedures are highly regulated, which ensures reliability but also comes at a cost.
