The main advantage of air freight is speed. The airplane is therefore the preferred means of transport for perishable or sensitive goods, for example for pharmaceuticals, high-grade technology, urgently needed spare parts or documents.
The disadvantages are found in the other two criteria:
- Air freight is more expensive than transport by ship or train.
- An airplane can’t hold as much cargo. Often, only the cargo space of passenger aircraft is available.
There are also goods that are considered a security risk and therefore are not allowed to be transported by air.
