Airline fare search engine

Here's a pretty good site link

Doesn't include Orbitz though which has pretty good deals sometimes. When you find something, it's a good idea to check the airline site itself to see if they have a better deal. Also, don't forget local travel agencies like King's Travel, Pali Travel, H.I.S. Travel. I was able to get $528 to Tokyo and back but it was on the UAL site for $517 and a friend got it for $519 from H.I.S. Travel. Just remember to shop around....
