Major airlines typically operate from specific terminals in airports, often based on long-term partnerships or agreements with the airport authorities.

What Are Airports?

Airports are facilities where aircraft take off and land, and they serve as transit points for passengers. An airport includes runways, taxiways, terminals, hangars, and various amenities for passengers. Airports vary in size and complexity, from small regional hubs to massive international gateways.
