I’ve been raving about Yahoo Farechase. It is great — especially for regular routes in the USA.

But I think I will switch to Mobissimo, a similar site, but which searches a larger number of suppliers to find you the best fare, or the best connection.

I was hiking with one of the Mobissimo developers in California. Though I had never heard of his site, he convinced me that Mobissimo could do a better job on international flights. I did an experiment searching for a fare Sydney to Hobart Australia next February. The best Yahoo farechaser could find was $208.

But Mobissimo found the discount Virgin Blue airline for only US$75.

Details on the Mobissimo service.

On a Vegas – Calgary flight search, Yahoo and Mibissimo search results were similar — though Mobissimo still better because it had more options.
