Like many people, we have friends & family spread across the country (yea, verily, the globe!) and every once in awhile my traveling feet get to being kind of itchy and I like to dream a little about going to visit.
For quite a few years, I've known about the Priceline service of city pair flight searches, where you type in where you want to travel and from whence, but in the past 6 months or so I've discovered a new and wondrous outlet for my travel dreams - Kayak.com
If you've never visited, you must. In order to have the most dreamy travel dreams, when you arrive at the home page, click on "deals" then on "buzz" where you can select "lowest fare" and sign up for email alerts notifying you of the best prices on flights for your selected cities. I've got flights from MI selected to places like Colorado, Oregon, and California. (are you sensing a theme here? GO WEST!)
And every day or two (you can opt for daily or weekly alerts) I get an email letting me know what prices other people are finding on flights for the next oh, year or so - or you can even plug in a price and Kayak will send you an alert when a flight is found in your price range.
For someone like me, with a minor case of wanderlust, this is a tool that gives me hope and the glimmer that yes, there is a possibility...
