What Are Interstate Flights Within the USA?

Interstate flights are flights that depart and land in two different states within the borders of a single country. For example, since the US is divided into 50 states, an interstate flight within the US would be one that departs from one of these states, such as Oregon, and lands in another state, such as Alabama.

What is an interstate flight from Hawaii?

Hawaii is an island state of the US, located in the Pacific Ocean. It's approximately 2000 miles away from the mainland USA. Flights between mainland USA and Hawaii can be classed as interstate flights as they depart from one US state (Hawaii) and arrive at another (e.g., Hawaii to California).

Are interstate flights the same as domestic flights?

There is a slight difference between interstate flights and domestic flights. All interstate flights are considered domestic, however, not all domestic flights can be considered interstate. For example, a domestic flight that departs in Los Angeles and lands in San Francisco cannot be considered 'interstate' because both of these cities are in the same state of California.
