Bing.com Travel Flight Predictor
 

I know it's just a prediction and isn't going to be 100% accurate and probably wouldn't be 50% accurate.

But has anyone tried it and from their experience how accurate has it been for them?

Used to be called Farecast. There are a few other threads here that talk about the accuracy. (Not suggesting that you should've known the earlier name, just giving you a tip that your answers may already be here...somewhere :))

It's been reasonably accurate when I've checked.

I just tried it and it said, "temporarily unavailable, try again later." I guess that is living up to the Microsoft tradition!
