Which direction do odd-numbered VOR airways/jet routes run?

Odd-numbered VOR airways and jet routes are designated to run predominantly in a North/South direction. This means that these routes are designed to facilitate traffic that is primarily traveling toward the poles, which is often the case for flights that require more latitude. By establishing these routes, air traffic control can effectively organize and manage traffic flow, ensuring that aircraft traveling in similar directions maintain safe distances from one another.

In air traffic management, the numbering system for airways and jet routes follows a convention where odd numbers are assigned to routes that run from the southern latitudes towards the northern latitudes. Conversely, even-numbered routes typically run in an East/West direction. This systematic approach aids pilots and air traffic controllers in navigating effectively, improving safety and efficiency in the airspace system.
