What is Air Freight: Works step and Solutions

Air freight is one of the fastest ways to move goods between countries, and companies choose it when getting cargo from one country to another quickly matters more than keeping transportation costs low. For both importers and exporters, it is particularly useful for time-sensitive inventory, high-value items, or shipments that cannot afford the long transit times of sea transport.

Simply put, air freight involves transporting goods by aircraft rather than by ocean vessel, truck, or rail. Although most international freight still moves by sea because sea shipping is usually more economical, air cargo can greatly reduce the time it takes to move goods between major trading markets.

Air freight is not the same as express or courier shipping, and understanding the difference helps you choose the right option for your cargo and avoid paying for a service you don't need.

Air Freight vs. Air Express

Air freight and air express are often used interchangeably, but they are not identical.

Air express shipments are generally handled by one courier company, such as DHL, FedEx, or UPS. The carrier manages most of the process from pickup through final delivery, which is why these express services are convenient for small packages that need to arrive quickly.

Air freight works differently because cargo can be booked through a freight forwarder and carried by one or more airlines before it reaches its final destination. Shipments can also be much larger than ordinary courier packages.

For businesses, the decision usually depends on the shipment size, urgency, destination, and how much control you need over the transportation process.

How Much Does Air Freight Cost?

Air freight costs are generally based on both the weight and volume of the goods being shipped. International air cargo rates can vary a great deal depending on the carrier and the capacity available.

With air freight, costs increase as cargo gets heavier or takes up more space on an aircraft, whereas ocean freight can move large shipments in a container at a lower per-unit cost.

Rates change frequently based on the route taken, fuel costs, market demand, the time of year, and the amount of aircraft capacity available. When aircraft capacity is low or demand is especially high, air freight rates can increase rapidly.

That is why you shouldn't treat an air freight quote as a fixed figure, since the actual cost will vary based on the shipment and market conditions at the time you book.

Costs and Rates for Air Freight Shipping

When working out the air freight charge, weight and volume are among the most important factors.

Airlines can charge based on the shipment's actual weight or its volumetric weight, also called dimensional weight. The higher of the two is usually used as the chargeable weight.

Volumetric weight is based on the space that a shipment takes up rather than just its weight.

For example, suppose a package is 40 cm by 40 cm by 40 cm; its volume is then 0.064 cubic meters. If the usual air freight dimensional rate of 167 is applied, the shipment will have a volumetric weight of about 10.69 kg.

The airline may still charge based on the higher volumetric weight even if the package weighs less.

This is important for importers of lightweight but bulky goods. A box might not be heavy, but if it takes up a lot of aircraft space, the freight charge can still be high.

Advantages of Air Freight

Although air freight is not the least expensive way to move most international cargo, it has several advantages that can make its higher cost acceptable.

Speed

The main reason businesses choose air freight is speed.

Because aircraft travel faster than sea vessels, air cargo can often move between major international markets in just a few days instead of several weeks.

For instance, a consignment sent from a factory in China to a warehouse in the United States would arrive far faster by air than by ocean.

For businesses that are handling urgent orders, seasonal products, or facing inventory shortages, the days saved can make a real difference.

Reliability

Air freight can in addition, offer more reliable transit times than certain ocean routes.

Ocean shipments can be affected by factors such as weather, port congestion, vessel schedules, labor problems, and other kinds of disruption, although air cargo is not entirely free from delays and can serve as a quicker option when a company wants to cut down the amount of time its goods spend in transit.

Tracking is also generally available throughout the entire journey, giving importers greater visibility into their shipment's location and expected arrival time.

Protection

Generally, air cargo reaches its destination faster and uses a separate transport system from ocean freight.

For fragile, sensitive, or high-value products, the shorter transit time can reduce exposure to some of the risks linked to long-distance international transport.

It doesn't make air freight risk-free; packaging is still important, and sensitive cargo may need extra handling or protection depending on the product.

When Should You Avoid Shipping by Air?

While air freight can handle many transportation challenges, it isn't the right option for every shipment.

The biggest issue is cost.

For large or heavy shipments, the price difference between air and ocean freight can become substantial. If the cargo is not time-sensitive, paying a premium for faster transportation may not make financial sense.

Air freight also has a larger environmental footprint than ocean shipping. Aircraft consume significantly more energy per unit of cargo than ocean vessels, so businesses focused on overall emissions may prefer ocean freight when delivery time allows.

Size and weight are additional considerations. Large, heavy products can quickly become expensive to move by air because airlines have strict aircraft capacity and cargo limitations.

If your shipment includes furniture, machinery, construction materials, or other bulky goods that don't need to arrive quickly, ocean freight may be a more practical option.

What Products Are Typically Transported by Air?

Because air freight costs more than most ocean transportation, businesses generally use it for products where speed, value, or urgency justifies the additional expense.

Common examples include:

• Electronics: High-value electronics often need to reach distributors and retailers quickly, particularly around major product launches or seasonal sales.
• Apparel: Fashion inventory can lose value quickly when seasonal demand changes. Air freight allows brands to move new collections from factories to markets faster.
• Pharmaceuticals: Many pharmaceutical products and medical supplies are relatively high-value and may have strict delivery or handling requirements.
• Samples and documents: Businesses frequently use air transportation when documents, product samples, or other small shipments need to arrive quickly.
• Seasonal products: When demand increases suddenly, companies may use air freight to replenish inventory instead of waiting for a longer ocean shipment.

The common factor is fairly simple: the cost of waiting can sometimes be greater than the cost of flying the cargo.

Rates & Fees for Air Freight Shipment

The freight rate itself is only one part of the final air shipping cost.

Depending on the shipment and the service you choose, an air freight quote may include additional charges such as:

• Fuel surcharges
• Security surcharges
• Cargo handling fees
• Airport or terminal charges
• Container freight station fees
• Airport transfers

For door-to-door air freight, other services may also be included in the total price, such as:

• Customs clearance
• Pickup and final delivery
• Cargo insurance or protection
• Documentation
• Other destination or origin charges

That is why it can be misleading to compare air freight quotes based on the advertised rate per kilogram.

A rate which includes pickup, customs clearance, and delivery might not in fact lead to a lower landed cost if another rate covers only airport-to-airport transport.

Are Air Freight Rates and Costs Changing?

Air freight rates change throughout the year.

The price can be affected by market demand, the amount of aircraft available, fuel prices, passenger travel, the seasonal peaks, and any disruptions in other modes of transport.

When ocean freight faces serious delays or disruptions, some importers shift urgent shipments to air freight to keep their supply chains running. This extra demand can strain available air cargo capacity and drive rates up.

Passenger aviation affects the air cargo market because many commercial aircraft carry freight in the space beneath the cabin. Changes in passenger flight schedules also change the amount of cargo capacity available on particular routes.

That is why companies should view air freight as a flexible mode of transport rather than assume the current rate will remain available forever.

Ocean freight remains the better option for many importers as long as there is sufficient time and the shipment quantity is large enough to justify the lower transportation cost. When delivery speed directly affects inventory, sales, or customer commitments, air freight becomes the more sensible choice.
