Air freight is one of the fastest modes for importing and exporting goods. Shipping by air is more reliable compared to shipping by sea. Both of these advantages of air freight come at higher cost when compared to ocean freight.
Air freight is a great option for shipping cargo in small quantities (Less than 500 kg). In such cases it might turn out to be cheaper than ocean freight as the fixed cost of shipping by sea is high.
Air freight is ideal for cases where the cargo needs to be transported rapidly. The transit time for air is generally a couple of days compared to the 2-4 weeks time taken to ship cargo by sea.
Shipping goods by air is more reliable, this makes it an ideal option for transporting goods of very high value. Electronics, apparels, pharmaceuticals, precious metals are generally shipped by air.
