Microsoft has been pretty busy today, adding two third-party services to its consumer and business brands. The first is a new integration with Farecast [coverage] on MSN's travel site. Users get a new module, containing airfare predictions and deals, that offers a listing of cheap airfares as well as an airport finder. Instead of jettisoning you out to Farecast's site, it will open up right inside of MSN--similar to opening up an app in Facebook.
On the business end, Microsoft has added the option to buy search keywords on Ask.com via Microsoft Office Live's adManager service. Office Live users will be able to get keyword advertising on both Ask.com and Live Search using the same platform.
