A cane that meets airline requirements should primarily serve as a mobility aid for passengers with special needs. It should be lightweight, compact, and foldable for easy storage during the flight. The handle of the cane should be ergonomically designed for comfort, and the bottom should have a rubber tip for stability and traction. It’s important to note that any additional features such as hidden compartments, blades, or sharp points are strictly prohibited for safety reasons. Moreover, canes with metal elements are allowed but expect them to undergo thorough security screening. Always remember, that the main function of a cane in the context of air travel should be to assist with mobility and not serve any other purpose.
