Airway (aviation)

In aviation, an airway is a designated route in the air. Airways are laid-out between navigation aids called VORs which act as intersections between the different airways.

In the United States low altitude airways appear on sectional and world aeronatical charts and are designated by the letter "V". High alititude airways, called jetways, appear on high altitude charts (that usually don't show topography as the low altitude charts do) and are designated by the letter "J".
