Does the U.S. government have any say in allowing a foreign airline to operate under an international treaty?

The U.S. government indeed plays a crucial role in allowing foreign airlines to operate in the country, specifically through the Department of Transportation (DOT). When an international treaty is established, it may set the framework for air services between countries, but the operational rights granted to foreign airlines depend on the bilateral agreements and regulatory frameworks that follow.

The DOT is responsible for issuing foreign air carrier permits, which are necessary for foreign airlines to operate flights to, from, or within the U.S. This process ensures that foreign airlines comply with U.S. laws, including safety, security, and economic regulations. The DOT evaluates various factors such as the airline's safety record, operational capabilities, and compliance with the terms of the treaty before granting these permits.

While treaties establish the legal basis for such operations, the DOT's oversight ensures that operational standards are met, which is paramount for maintaining national security and safety in U.S. airspace. Hence, the correct answer highlights the vital role the U.S. government plays through its regulatory bodies in the context of international aviation operations.
