A couple of other unique features worth checking out are the charity linked flight purchase scheme, and the travel classifieds sections. The classified area contains some really good deals. Hotels and car rental are also available. MSN Expedia - Fast and straightforward to use. A one stop shop for flights, hotels and car rental.
Affiliate companies provide a wide range of options in cruise, vacation packages and other deals.
Frommers - Offers a huge and diverse range of flight options. Lowest fares shown however are in our experience seldom available when it comes to the serious business. Despite this Frommers is well worth trawling through, particular if you tend to travel off the beaten track. Not surprisingly budget travelers are well catered for, but canny business movers should not overlook some of the upper class deals available here. The Travel Auction and Grab Travel Deals are also worth checking out.
