Looking for deals on airline tickets inside the US(Tacoma, WA to Philadelphia, PA?)

[Matrix2k3]

My friend is trying to get her boyfriend who is now living in Washington with his father, to Philly for our senior Prom (in June). Problem is his dad is stingy and neither of them have jobs right now, plus, well, cheaper is better. I wanna help them out, can anyone point me in the direction of some good deals on airfare? Preferably round trip with a stay of about a week?

I would check out FareChase - they search a bunch of sites at the same time to get the lowest fare.

www.hotwire.com is what I always use and they are cheap as long as you are not to picky about details of the flights such as, Arrival and departure times and so on.
