As a travel companion, your responsibilities are to assist your clients with their needs when they travel. Your duties vary depending on the client and destination. For example, you may join elderly clients on trips or supervise children when they take flights without their parents. In some cases, your duties are to drive your clients if they are no longer able to drive themselves or have difficulty driving under certain conditions, such as at night. You may also provide medical assistance, such as reminding your clients to take prescription medicine. Some travel companions provide support and company, while other professionals may have more significant responsibilities, such as bathing and feeding their clients.
