The new airfare search engine

You may have herd of Bing, MSN's latest attempt to take some of the search engine business from Google. Of more interest to travelers is Bing Travel (http://www.bing.com/travel/), their new travel search engine. The interface is very similar to www.kayak.com - very flexible and intuitive, allowing you to search many options without having to start over (e.g. using different airports, leaving before or after a certain time, acceptability of red eyes and number of connections). I find myself using these options all the time so I have come to depend on them. What Bing adds, however, is integration with Farecast, the website that predicts whether airfares will go up, down, or stay the same. I would guess that their predictions may have been a little off this year because no one foresaw the precipitous decline in airfares coming. But still, they claim 75% accuracy and that seems better than tossing a coin. They also have various attempts at creating "community", the latest marketing buzzword, with blogs and Facebook and Twitter - this is less appealing to me because who has time to read blogs unless you have a specific reason to (on the other hand it would be totally cool if your search for specific flight itineraries or hotels brought up relevant blogs). In any case I will probably continue to compare kayak and bing for awhile but it is likely that bing will become my travel search engine of choice if I don't find any bugs with it.
