Yes, walking sticks are TSA approved and can be brought onto an airplane. However, travelers should remember that any metal parts such as a cane tip must go through security screening or x-ray machines and may need to be removed from the stick during the process. Additionally, collapsible canes must also fit within carry on luggage restrictions (no more than 22x14x9) in order for them to be taken onto the aircraft. It is important for passengers flying with a walking stick to inform their airline of this prior to arriving at the airport in order to avoid any potential delays or issues with boarding.
