Planning Holiday Travels

I am planning a trip to Canada to get my TN visa if everything goes smoothly. I tried several websites from my travel 2.0 list and found one that was particularity useful, farecast. Since several of my friends from Toronto said they were planning to visit me, I decided to look at their airfare prices if they were to book their flights today. Farecast graphed it for me so I can see when it would be cheapest to travel. How cool is that? It's not that hard, just take the lowest prices at various dates and plot it, but it's so cool. From Toronto to San Francisco:



Too bad they don't have all the cities available to be graphed. This is a search from San Francisco to Vancouver and Toronto.
