Chris Sherman reported Wednesday that Yahoo's Farechase Adds Features. New features include;
(1) Integration into the main Web search. For example, a search on flights to st. louis puts this Yahoo Shortcut at the top of the results.
(2) They added a social networking element, where you can save fare searches to Yahoo My Web. I conducted a search and saw a "save to my web" link at the top. Attached is an image of how it looks, cropped a bit, click on the image for a full view.
(3) They also integrated satellite imagery of Yahoo Maps beta into FareChash, but I am not sure how that works.
