Where can i find really cheap flights?

I am going on a trip very soon and am planning on flying home, is there any place online that i can find really cheap flights? I also heard that one airline is offering $50 flights anywhere in the US??

HELP PLEASE!!Where can i find really cheap flights?
Where are you flying to and from? By home do you mean a different state, or a different country? With providing no information, we cannot advise you of your best options..
Not knowing where you are flying and where you are flying from, we cannot help you. I can suggest you try http://www.kayak.com but summertime is usually an expensive time to fly and it is even more so if you try to buy a ticket at the last minute. As for $50 flights, I have not heard of that. JetBlue did have flights for $10 to celebrate 10 years of being in business, but that deal has passed. You can also see if Southwest Airlines has anything.Where can i find really cheap flights?
Check out Dohop.com - I think you'll find info and prices for almost every flight in the world there.
