I just hate trying to figure out when to buy airfare. It seems like the minute I buy a plane ticket, the rates go down. The last time I had to book air travel, I used Bing's travel alerts. Just go to bing.com, select Travel, and set up a Travel Account. Once you have a travel account, you can set up a fare alert by specifying your departure and destination airports and the dates of travel. Bing will track the fares, using data from all the major travel websites, and send you alerts as the fares go up and down. Bing will also tell you when it is recommended that you buy, based on those trends.
This is a great time-saver, not to mention a money-saver.
