One of the most significant differences is the time required for transportation. Air freight takes approximately one third to one quarter of the time as sea freight, with an average of eight days for air freight and as much as a month for sea freight.
Secondly, there is a difference in price. There will be a difference in cost between air freight and sea freight per kilogram. This difference of about 3-4 dollars per kilogram will certainly add up if you are shipping large quantities of goods. There is a third major difference in insurance premiums, which relate, in part, to the amount of time it takes to transport goods.
Due to air freight’s shorter transit time and resulting reduced risk of damage, insurance premiums are lower. Additionally, sea freight can be more environmentally friendly than air freight.
