May I make a suggestion?
If you are making travel plans to the Convention (or anywhere, for that matter), go to each of the websites of the airlines that you would consider taking, and sign up for their frequent flyer programs. Then, most will also have a place to sign up for specials for cities to which that you're interested in going. Sign up, and you'll get a weekly/biweekly/monthly comparison of how much it will cost. That way, if a huge sale comes up, you can jump on it immediately!
The expedia, travelocity, and orbitz sites sometimes offer that, too. It can't hurt to check!
