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.
There are some vendors whose travel agent commission model is a flat rate. Yes, there are some vendors where the commission is actually standard and predictable! Hooray! Hotels and car rental companies typically pay travel agents 10% commission and thatâs that. There are small variances but car and hotel only bookings are probably the most predictable commission level in this whole mess.
