A travel website is a website on the world wide web that is dedicated to travel. The site may be focused on travel reviews, trip fares, or a combination of both. Approximately seventy million consumers researched travel plans online in July 2006. Individual airlines, hotels, bed and breakfasts, cruise lines, automobile rental companies, and other travel-related service providers often maintain their own web sites providing retail sales. Many with complex offerings include some sort of search engine technology to look for bookings within a certain timeframe, service class, geographic location, or price range.
