Travel agencies make their money in a variety of ways. The products agents sell have built-in fees that result in a profit for the agency. The amount of the fees and the ways in which they are earned and distributed differ by the type of product sold and the suppliers who provide that product to the agency.
Travel agents book business and leisure travel for customers. As a travel agent you will sell holiday packages and give travel advice. Your role is to make travel planning easier, and to make sure your customers have the best trip possible. For this role youâll need to be well organised and have an eye for detail.
