There are different modes of transport, and each mode has its own benefits and drawbacks. Air freight is often used for high value and low volume shipments, as you might already know.
When your goods need to be moved quickly, air freight is the best solution compared to sea freight or road transport
The arrival and departure times of flights are highly reliable, as airlines tend to be very on top of their schedules. Even missing a flight wouldn't cause much delay as there are usually flights departing every hour
Many airlines have a large network of destinations that covers almost the entire world. This means that you can send the shipment to nearly every destination
As the transportation time for air cargo is comparatively short, the insurance premium is lower. Even if air freight can be expensive, this brings about savings in terms of lower insurance costs.
Shipping by air offers the advantage of a high level of security, as the airport safety controls over cargo are tightly managed. Tightly managed airport controls also reduce the cargo exposure to theft and damage
With the quicker transit times of air freight, you have less need for local warehousing and do not need to keep items in stock. Customs clearance, cargo inspection and cargo handlers are more efficient, as most cargo is cleared within a matter of hours
Normally, air shipments require less heavy packing than for example ocean shipments. This means that you save both time and money to provide service for additional packing
Many companies give you the opportunity to track your goods using a web application, which means you can monitor the status of your cargo from departure to arrival to keep constantly updated.
