When this next site provides you with a fare quote, it gives you a forecast indicator arrow. Green means the fare will likely be going up, so buy it now. A red arrow means to wait as it will likely be going down. My son tried out this page for a recent trip, but found that both airports he was using (Grand Rapids, MI and Tampa, FL) were not part of the system, so he couldn’t get any rate forecast information. So, I’m guessing this will only forecast for very large airports. However, there is a feature to request future forecasting for your airport if it isn’t already supported. Again, I haven’t tried it personally, but just thought I’d pass it along. TIP: Try www.farecast.live.com
