Farecast
One of my favorite sites of the last year is Farecast. Farecast aims to predict if airfares will go up or down to your destination. I used it at Christmas, watching the fares for a few months to see when the best dates for traveling the cheapest would be.
Even better, you can set up RSS feeds for your specific flight parameters. For example, say you needed to fly from DFW to Columbus, OH the first week in April. Input those dates, your cities, and search for the lowest fares across most airlines. Then, click the link for “Track this trip with RSS” and you can add the RSS feed for that specific date/city combination to your favorite RSS reader. The RSS feed will help you monitor if fares are estimated to be increasing or decreasing in the coming weeks.
It’s a must-have for the savvy traveler.
Kid,
I am so glad that you are back to posting (somewhat) regularly.
