Today, travel purchases come in many forms. The travel agent is at the center of these transitions.
There are five main groups that travel and tourism law is concerned with: providers, sellers, travelers, regulators, and hosts. Travel agents fall under the category of sellers of travel, a group that also includes tour operators, consolidators, wholesalers, telemarketers, travel clubs, informal travel promoters, pseudo–travel agents, Internet websites, and companies offering unsolicited e-mail postings. Sellers of travel may be assisted by escrow banks, surety, and insurance companies.
