Air freight is a mode of transport that involves moving goods by air, usually using airplanes or helicopters. Air freight has some advantages and disadvantages compared to other modes of transport, such as road, rail, sea or pipeline. 

The advantages of Sea freight shipment are as follows:

• High speed: Air freight is the fastest mode of transport, especially for long distances.
• Global reach: Air freight can access almost any destination in the world, regardless of natural or human-made barriers.
• High security: Air freight has a high standard of security, as airports have strict controls and regulations to prevent theft, damage or loss of goods
• Low insurance costs: Due to the short transit time and high security, air freight usually has lower insurance costs than other modes of transport
• Reduced packaging: Air freight does not require extensive packaging or warehousing, as goods are handled less and transported faster.

The drawbacks of carrying freight by sea include:

• High cost: Air freight is the most expensive mode of transport, as it involves high fuel consumption, maintenance costs, airport fees and taxes.
• Limited capacity: Air freight has a limited capacity, as airplanes and helicopters have restrictions on weight, volume and shape of goods.
• Weather dependency: Air freight is dependent on weather conditions, as fog, rain, snow or storms can cause delays or cancellations of flights.
