Does any one know were to get really cheap airline tickets?

You can find great deals for tickets on kayak.com. My dad uses kyak to get tickets for flights all the time when he travels for work. He just went to Peru recently and got his tickets through kyak.com. Basically kyak.com is like a search engine for tickets. You punch in some information like when you want to leave, time, date, destination preferences...direct, coach, first class...etc. Then kyak.com browses through millions of ticket sites and provides you with the cheapest tickets that meet your preferences. Also, as I know from my dad the longer in advance you book the tickets the cheaper they will be. As you get closer tickets will be more expensive...usually.  more
