Different Methods of Air Transportation
More than a century has passed since the Wright brothers turned the dream of flight into reality. Over the last 120 years, the aviation industry has experienced extraordinary progress.
Among the most important applications of modern aircraft are passenger transportation and air cargo shipment. The speed and operational capability of aircraft have enabled the movement of valuable goods in the shortest possible time.
In addition, emergency assistance during natural disasters can be delivered by air. Although maritime transportation accounts for more than 70 percent of global transport, the absence of air transport would create significant deficiencies in the international logistics and transportation industry.
Air Cargo Transportation
Types of Air Cargo Services
In the air transportation industry, cargo is generally shipped through two primary methods: passenger excess baggage shipment (freight) and commercial cargo (cargo shipment).
Passenger Freight (Unaccompanied Baggage Shipment)
This method concerns baggage for airline passengers. In practice, each passenger may carry a limited amount of baggage, typically 20 to 30 kilograms. If a passenger’s baggage exceeds the permitted limit, excess baggage charges apply. Passenger freight is a method used to avoid paying excess baggage penalties. Under this method, the freight is shipped to the passenger’s destination by cargo aircraft. The sender must hold a valid airline ticket. Passenger freight can reduce air shipping costs to approximately one-third of what would otherwise be charged as excess baggage. To use passenger freight services, the passenger must present personal identification and the flight ticket at the airport cargo facility.
Required Documents for Passenger Freight
- Identification documents.
- Passenger passport.
- Printed flight ticket.
Commercial Cargo Shipment
Commercial cargo shipment is the primary method for transporting and sending goods by air. This method is used for commercial and export shipments and is typically selected for goods of high economic value or with strict time constraints. It should be noted that air cargo transportation is generally more expensive than land or sea transportation. Commercial cargo shipment requires the sender to provide a valid commercial card.
Required Documents for Commercial Cargo
- A letter of introduction from the exporting company or the commercial representative.
- Commercial card.
- Documentation proving lawful importation of the cargo, if the goods are not of Iranian origin.
- Specific permits, including health and standard certificates, for the export of certain goods such as industrial equipment, saffron, and similar items.
- MSDS documentation for laboratory and petrochemical products.
Shipping Household Goods by Air
Many individuals planning to immigrate to other countries wish to transport household items. Passenger freight is often the most suitable method for sending personal belongings and household goods. For passenger freight shipments, it is generally advisable to initiate the process approximately two weeks prior to the flight. This timing helps ensure that the shipment arrives close to the passenger’s travel schedule.
Air Cargo Costs
Various factors influence the cost of air cargo transportation, including service type, packaging, insurance, transportation fees, airline tariffs, warehousing, duties, and other related charges. Air freight companies offer different service levels, each with its own pricing structure. For example, door-to-door delivery typically involves higher costs. Determining customs duty costs generally requires consultation with the company’s specialists. If the value of the goods is below a defined threshold, customs duties may not apply. Insurance premiums are also calculated based on the type of service and the declared value of the goods.
How Air Cargo Costs Are Calculated?
Air cargo tariffs are set by airlines. In most cases, passenger freight tariffs offered by foreign airlines are higher than those of domestic carriers. It is recommended that, during consultation with a shipping company, you obtain a clear explanation of all cost items. This ensures full transparency regarding the fees charged for each service.
International Express Air Mail
If a shipment is small, international express mail services may be used. Express mail deliveries typically take between 5 and 14 business days.
