Cabotage refers to the transportation of goods or passengers between two points within the same country by a foreign carrier. This practice is often regulated by national laws to protect local industries and ensure safety standards. For example, in the United States, only American-flagged ships can transport goods between U.S. ports under the Jones Act. In aviation, cabotage laws can restrict foreign airlines from operating domestic flights within a country. These regulations aim to support local airlines and maintain control over air traffic. Countries may have different rules regarding cabotage, impacting international trade and travel.
