We routinely advise when planning a vacation or making plans for travel, take time to check the reputation of the company you choose before making a buying decision. In California, a travel company or agent who sells, or arranges air or sea transportation must register as a seller of travel with the California Attorney Generals office, and post bond with the state to protect consumers from fraudulent promotors. This registration requirement applies to all sellers of travel who have their place of business in California, and sell to out of state, or California residents, or, are located outside California but solicit California residents. You can check seller registration by calling the Attorney General's registrar at 213-897-2627, or visit their website at http://www.caag.state.ca.us.
