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.
As an experienced travel agent you could earn between Â£15,000 and Â£25,000 a year. If you are in a senior role, this could be up to Â£35,000 a year or more. For regional management and senior management positions, you could earn significantly more. Travel agents often get commission based on meeting performance targets.
