Air Freight Cost: Is Air Freight Better Value For Money Than Sea Freight?

Air Freight

Until recently more than 90% of the world’s goods were transported by sea freight, with 70% shipped as containerised cargo. Ocean or sea freight has been responsible for such volumes largely due to costs, with ocean freight shipping charges often more than 12-16x less per kg than that of air cargo. This is however no longer the case, and as a result of the culmination of a number of key factors the traditional cost-benefit balance of ocean freighting has been shifted. So, is sea freight still better value for money for your business, or have things changed?

Air freight vs sea freight

The decision as to whether to send goods by air or sea freight is decided by factors such as size, weight, contents and of course the speed at which goods are required to be delivered. Whilst air cargo costs have typically been far higher (12-16x more) than that of sea freight, delivery speeds were often around 30x faster.

Due to a variety of factors including the Covid-19 pandemic, Brexit and other extenuating circumstances including the ‘Ever Givens’ blockage of the Suez canal, these figures have changed. Increased demand, a shortage of containers and personnel and complications loading and unloading cargo have meant that the price differences between air and sea freight have decreased considerably whilst disparities between delivery times has increased exponentially.

Based on this data, choosing the optimum freight service for your business purposes becomes a difficult task.

Which freight option is best for my business?

Cost

Air freight

Air freight prices are calculated by one of two methods:

  • Actual weight (gross weight) or
  • Volumetric weight (dimensional weight)

As a result, goods shipped by air are typically either of a high value per unit, or time sensitive goods including pharmaceuticals, electronics and perishables.

Sea freight

Sea freight costs are calculated on a price per container basis, typically either 20ft or 40ft, or on a cubic metre basis if goods are less than a container load.

Whilst costs have increased dramatically, they are still considerably cheaper per kg than the price of air cargo. Due to the sheer capacity of sea freighting it is also possible to ship much larger goods in comparison to what is permitted by air.

Air freight

Not only do planes offer limited capacity, but not all goods can be sent by air freight and some goods including hazardous substances such as pharmaceuticals actually require specific licenses. As an IATA (International Air Transport Association) associated company, we’re fully accredited to handle hazardous and dangerous cargo and are covered to import and export this worldwide.

Sea freight

Sea freight allows for considerably larger and heavier goods to be transported, and is therefore the preferable option if moving goods in high volume or above a certain size. It is worth considering that sea freight can experience a more turbulent journey than air cargo and improperly packed goods may incur damage.

Timescale

Air freight

Dependent on the nature of the goods being shipped the cost of air freight rates is sometimes trumped by the requirement to meet urgent deadlines. This is especially true of any goods destined for a fast paced commodity market in which time is of the essence. As an example, air cargo arriving from Asia to the UK can often take as little as 3 days.

Sea freight

In comparison, sea freight has relatively slow transit times and for the same journey it could potentially be up to 35 days. In addition, the impact of the above mentioned factors has led to many ships being delayed in port or unable to load/unload cargo.

The importance of timescale is therefore entirely dependent on the nature of goods being shipped.

Environmental impact

Air freight

Air freight leaves a considerably larger carbon footprint than sea based shipping. Airplanes emit 500 grams of CO2 per metric ton of freight per km of transportation, and often make 3-4 journeys per day on certain routes.

Sea freight

By contrast transport ships emit only 10 to 40 grams of CO2 per km. A study by the UK government shows that planes create 44 times more CO2 than ships when carrying the same freight over the same distance.

Reliability

Air and sea freight

Both air and ocean freight offer the sender considerable peace of mind and goods typically arrive with a 99.99% success rate.
