Holbrook Travel Gives Incentives February 18, 1998 Share 1 -- GAINESVILLE, Fla. -- Holbrook Travel here introduced an incentive plan to make the selling of its natural history tours more beneficial to travel agents. Under the plan, agents earn 10% commission for the first 10 passengers and 12.5% for the 11th to 20th passengers. The commission is 15% on each passenger thereafter, and any agency that sells more than 10 passengers will receive 12.5% pay on all passengers sold -- even the first 10 -- in 1999. Included in the program are Holbrook's scheduled tours to Belize, Costa Rica, Guatemala, Honduras, the Galapagos Islands and Peru as well as those to Kenya, South Africa, Tanzania, Uganda and Turkey. Increased commission is not paid on custom groups or FITs. Holbrook Travel, (800) 858-0999.
