Air Freight: A Market Study with Implications for Landlocked Countries

One of the principal factors limiting the volume of airfreight in developing countries is the lack of significant volumes of two-way activity.

To facilitate air freight, landlocked countries need to improve operations at their airports and liberalize access for foreign airlines.

Potential markets

The demand for air freight is limited by cost, typically priced 4–5 times that of road transport and 12–16 times that of sea transport. Air freight rates generally range from $1.50–$4.50 per kilogram, while the value of air cargo typically exceeds $4.00 per kilogram. Commodities shipped by air thus have high values per unit or are very time-sensitive, such as documents, pharmaceuticals, fashion garments, production samples, electronics consumer goods, and perishable agricultural and seafood products. They also include some inputs to meet just-in-time production and emergency shipments of spare parts.

Demand for air freight exports has been limited from landlocked developing countries because most enterprises ship small volumes of low value goods. The main exports shipped by air from developing countries are cut flowers, electronic parts, and fresh fruits and vegetables. Imports by air typically include high value consumer goods. However, without a significant outbound flow, the inbound air freight rates are higher — reducing the types and quantities of goods transported by air.

Gaining competitive advantage

The use of air freight can create competitive advantages. For example, producers will agree to shorter order times if shipments possibly experiencing delays in production or cargo clearance can be shipped by air. Similarly, manufacturers of garments, electronics, and other goods will compete for larger orders by shipping the large initial order using ocean freight and then using air freight to replenish inventories if demand is greater than expected.

Diversifying

Air freight can also be used as part of a strategy for diversification — to introduce products with shorter shelf lives or to provide reliable delivery of smaller volumes in new markets. Once the market has been established and volumes increase, the manufacturer can reconstruct supply chains by using a less costly mode of transport.

These strategies are particularly important for landlocked countries that have unreliable land transportation or long and uncertain clearance procedures at their borders or foreign gateways. Finally, where exports require cold chains, air freight can present the only means for guaranteeing continuity.

Shipping samples

Air freight is critical in the shipment of product patterns, designs, and technical drawings. While this is not a major source of air cargo, it is critical for manufacturers who export manufactured products. More important is satisfying the need to exchange samples with potential buyers. For contract manufacturing, this includes the initial prototype sent for the buyer’s approval so that the order can go ahead followed by a head of production run, which must be approved before starting full production. Samples may also be provided for testing or for promotion campaigns.

Moving cargo quickly

Since the advantage of air freight is much shorter transit times, cargo must move quickly through an airport. The time for cargo operations depends on four factors: customs clearance procedures, cargo inspection procedures, the efficiency of cargo handlers, and the layout of storage facilities.

Customs clearing

For imports the customs procedures are critical. The clearance requires both the airway master bill, sent at the time the flight departs, and the customs declaration, filed by the brokers after the cargo had been shipped. In some countries the customs authority at the airport uses the same procedures and systems as at other international gateways, and inbound cargo can take up to a day to be cleared. In others the procedures are adapted to the requirements of air cargo, with all transactions conducted electronically and cargo cleared within one or two hours on a 24/7 basis.

Inspection equipment

For exports the documents are filed at the time cargo arrives at the airport, and the inspection is done at the same time so that cargo can be loaded within a few hours of arrival. Before X-ray scanners, a 24-hour cooling period was typically added to the transit time, but this has been eliminated. Most of the scanners are for baggage and small packages, so the cargo must be unloaded from the truck in loose form and scanned before being built into palettes. At larger airports with significant cargo traffic, full palette scanners allow shippers to build their palettes off-airport and to load them on the aircraft within a few hours.

Cargo handling

Cargo handlers at the airport should ensure efficient and secure handling of the cargo allowing airlines to compete with each other. Where the cargo volumes are fairly small, an exclusive contract is used, and the contractor must provide appropriate equipment for unloading the different types of aircraft.

In many developing countries the national carrier enjoys a monopoly, which presents a problem if the carrier is an inefficient state owned enterprise. This situation also introduces opportunities for discriminatory behavior in handling competitor’s cargo. In some other airports a private contractor maintains a monopoly, but performance is often regulated through productivity incentives. Since the possibility for discriminatory behavior remains, competition must be introduced as soon as there is enough cargo, or carriers should be allowed to handle their own cargo.

Warehousing

Many storage facilities at smaller and older airports are fairly basic. This has little impact on cargo storage since most cargo does not stay at airports. Generally exports are time-sensitive, and the imports are high-value, fast-moving goods.

Modern warehouses have loading docks to speed truck turnarounds and minimize vertical movements of cargo. Export facilities for exports have large areas for scanning, inspection, building palettes, and gathering the cargo for specific flights. Separate facilities for imports have offices and inspection areas to facilitate customs clearance procedures and to allow for segregation of cargo into truckloads. For perishable cargo, these warehouses have temperature-controlled rooms for maintaining the cold chain between the truck and the aircraft. These warehouses also provide some bonded storage for high-value cargo.

Where there is enough traffic and space, airlines or larger forwarders will invest in such facilities. Where there is a lack of space or each airline handles a small amount of freight, the airport has to invest in a multiuser facility. In both cases, the airport must finance the construction of the complementary taxiways and the aircraft parking area.

Where these four elements, customs procedures, inspection equipment, cargo handling services, and warehousing are integrated into an efficient operation, most cargo will pass through the airport within a few hours. This minimizes dwell time and substantially reduces the space required to handle a specific volume.

Costs

As a result of the recent spike in oil price, fuel now accounts for about half the annual cost of operating an aircraft, whether for cargo and passengers. Because fuel consumption is roughly proportional to the aircraft weight and the distance flown, the marginal cost for carrying cargo is computed based on weight and destination. For belly cargo the space is offered “as available,” since priority goes to passengers and their luggage. Because the rate is usually set based on marginal cost and then adjusted for the level of service. For charter services the rates are usually higher, reflecting the incremental distance flown, including the empty legs, and the balance between demand and available capacity.

For shorter distances air freight rates per kilometer are higher because a greater part of the trip is spent both on the ground and more time in the air is spent climbing and descending. It is therefore often preferable to use road transport on the leg between the domestic source or destination and the transshipment hub.

Future air freight in landlocked countries

The main difficulty for landlocked developing countries is to generate enough traffic to attract air freight services that are both frequent and competitively priced. Permitting free competition, or “open skies,” for air cargo services can be significant but not sufficient if most cargo is transported as small shipments in passenger aircraft. Liberalizing passenger services to include fifth freedoms has been a greater challenge, especially in countries with a national carrier and limited passenger volumes.

In the short run, higher fuel prices are expected to result in slower growth of air cargo traffic or even in a possible downturn. Over the longer run, traffic should continue to grow, but air freight will increasingly be integrated into multimodal supply chains that provide a better balance between cost and time.

Air freight will also open new markets by providing fast and reliable service for initial deliveries of product. Air freight will continue to support production activities, especially the exchange of samples and delivery of critical spare parts and high-value inputs. Finally, air freight will increase in importance in supporting reverse logistics, including repair and warranty work for electronics and other high-end consumer goods.

Nevertheless, air cargo is expected to decline as a mechanism for minimizing inventories and supporting just-in-time production. For these activities the higher cost of transport offsets the benefits of minimizing inventories in the supply chain. While it is important for potential exporters to have access to air freight services, they also must manage their supply chains to provide a competitive balance for the cost, speed, and reliability of shipments.
