I purchased my airline tickets for my trip out west this summer. We ended up finding the best deal at AirFareWatchdog.com. All you do is sign up at their website and enter in your email address and the airport you want to fly out of. They will also send you deals from any surrounding airports. You need to check the email every day as the deals disappear fast. We were able to get tickets to Seattle for just $226 round trip. I think this is the best deal I have ever received! This takes a load off my mind, since my only other option was to rent one of those travel trailers and drive to Seattle!
Now I just need to make hotel and rental car reservations.
