The cost of using a travel agent is generally marginal, and often, they won't charge you at all. Much of their money comes from commissions the hotels and wholesalers pay them. Before you decide to book with a travel agent, inquire whether or not they charge fees.

Travel agents may charge service fees, flat-rate trip fees or consultation fees. For example, you might pay a flat rate of between $100 and $500 for a travel agent. There are some travel agents who operate with no cost to customers and instead receive commissions on the flights and accommodations they book.

Travel Agents Take the Stress Out of Planning Travel agents help clients with all types of situations and are immersed in travel full-time, so they're aware of details you might not think of when planning on your own. Their knowledge and experience also gives them the foresight to prevent potential problems.

Consultants rely on personal knowledge and destination experience. Agents can access a profile of their clients. Consultants have personal knowledge of their clients' likes, dislikes, travel background and interests. Agents will call the frequent flyer desk on behalf of clients, for a fee.
