SEA-AIR
Sea freight is a method of transporting large quantities of product via cargo ships; goods are packed into containers and these containers are loaded onto a vessel, where they will be sailed to their destination country.
The cost difference between sea freight and air freight depends on the trade and the cargo you ship. As the airplane capacity is typically limited by weight and the sea freight capacity by volume, the difference in price for sea freight and airfreight is less for light cargo than it is for heavy cargo.
