Many of you probably start planning your trips fairly early, especially if looking for flights to Europe, across the US, or a complicated itinerary.
When you start checking airfares, do you wonder if they will go down? Should you wait? How do you know?
One tool I found is to use Kayak. Put in your cities and dates. Then use their feature called Price Trend which shows whether the fare for your flight has been rising or falling. It also advises if you if you should purchase now or wait, with a confidence percentage.
