Travel Agent Selection and Company selection are both useable via EZ Searches and refresh the screen with the new rates, if appropriate. Travel Agents are referenced by their IATA number or by name. Many Travel Agencies have the same name, but the IATA # is always unique so we recommend using the IATA number. To edit the Travel Agent information or the company information, click on the underlined word, "Travel Agent" or "Company" after the company or travel agent has been selected using EZ Search.

Guarantee by defines how the guest is going to pay for the booking and terms are setup by the GM in the setup area but commonly include Credit Cards (Visa, Mastercard, Amex, Discover, etc) Direct Bill and possibly non credit card payment types (Cash, Traveler's Check etc).
