I would use http://www.sidestep.com and put your information in. They will search all the other websites for the best prices. Also check southwest as they do not share their pricing with others. If you are flexible on travel dates you can save a lot of money.

I just looked around and the best deal I can find is hotels.com has a flight leaving as early as next monday on delta for $250 roundtrip.

Check sites like Southwest airlines or US Airways. Also do a search on kayak engine. It will check all airlines going to Vegas and all major travel sites and return the cheapest fare. http://www.lasvegas-how-to.com/cheap-flights.php
