I always compare airline tickets and various routes online, and then buy my airline tickets about two weeks before I travel. I assume that is the best way to get the best price. Now there is a site that predicts if you should buy now or wait to buy your airline ticket.
Digg.com posting: “It’s probably in the back of your mind every time you click on the purchase tab: did i get the best price on this airfare? There’s no worse feeling than checking back later and seeing the price has dropped. Buy now, buy later — how do you know? Well, a Web site claims it can predict whether ticket prices will soar or sink.”
