Where can i find the cheapest airfare online?

your probably better off checking out the airlines websites. they all claim that their fares are always cheaper than the expedia/orbitz/hotwire kind of sites. i only fly continental, and the fares on their website are always a few dollars cheaper than those "discount" sites. but generally, no matter where you go, the flights are going to cost the same. unless you go to priceline and "name your own price" you may be able to get a cheaper flight on there, but you have no control over what time of day you fly and on what airline etc. delta runs out of atlanta and newark is a pretty big airport, so fares from there shouldn't be to much.
