Answer:
The answer is: National airports: general aviation flights. International airport: for international or intercontinental routes.
Step-by-step explanation:
National Airports: A national airport, also called domestic or domestic airport, is an airport that serves only domestic domestic flights to the same country, also called domestic flights. Domestic airports lack customs and passport control offices and therefore cannot serve flights to or from a foreign airport.
These airports generally have short runways where only small aircraft can maneuver and where general aviation flights operate.
An International Airport is an airport typically equipped with customs and immigration facilities to manage international flights with other countries.
These airports are normally large, and often have large runways and adequate facilities to cater to the large aircraft that are commonly used for international or intercontinental routes.
The answer is: National airports: general aviation flights. International airport: for international or intercontinental routes.
