+1. I do use kayak.com a lot to find low fares though, and go back to the airline's site to grab my flight. Also, on my last 3 trips to Vegas, I booked my flights one way at a time vs. round trip. Last year, I got a $79 one way fare (Continental) & a $114 one way fare (Southwest) from Raleigh-Durham to LAS. Last week, I got a one way fare from RDU to LAS for $128 on Delta. I could find no other round trip fares less than $360. I'm sure results would vary depending on where you are flying from or to, but this could help.

If you need to make changes, this can be trouble. Also, booking rooms through a third party eliminates any possability of being comped.
Good Luck!
