An airway is a passage or route through which air can flow. In the context of aviation, it refers to the path that an aircraft takes while flying from one place to another. This could include various routes and corridors designated for commercial flights, as well as specific flight paths within controlled airspace. The term "airway" may also refer more broadly to any route or channel through which air can flow, such as a natural passage in the landscape like a valley or gorge that allows wind to pass through.
