I haven't used google flights, hille141. I've used many of the others. Thanks for the suggestion. Is it just me or would it be nice if one of these sites gave you the option to select a few of your favorite flights and notify you when they are within a certain price range? I have certain flights on Delta, Airtran, US Airways, and American that I know I want to fly. The thing I don't like is that I will get a notification that the flight is in the range and go to the site to check it out. I then see that it is an overnight flight? I don't care how cheap it is, I am not doing an overnight flight from Nashville. Wish some programmer would add that feature!!
