Travel industry researchers estimate that demand for independently booked travel is set to rise by 80% in the next five years. Both Yahoo! and AOL recently announced that they were improving their travel offerings and setting up as online travel agents. Both companies are developing specialised travel search engines (due to go live in early 2005) that will allow users to compare prices from a range of different travel agents, airlines, hotel groups, resorts and hire car companies. The difference between these offerings and sites such as Lastminute.com or Travelocity is that the Yahoo and AOL travel site will include fares offered by budget airlines. At the moment, other companies do not include listings of many of the budget airlines as most refuse to pay a commission to list their services.
