A travel agent books travel for customers and is paid by suppliers a commission on the booking. For things that suppliers do not pay a commission on, a travel agent also can charge the client a service fee for his/her time. An example is if you were to book a hotel for a client, the hotel would then send a check to the agency after the client checked out. Most hotels pay 10% of the price of the hotel before taxes and fees. A $100 per night hotel reservation would mean $10 a night for the travel agent who made the booking. This hotel would cost the same whether the customer uses a travel agent or books through the hotel directly. In many cases the travel agent can get a better price. It costs the customer nothing to use the travel agent unless the travel agent charges service fees.
