Where can I find the cheapest flight tickets? What airlines should I avoid?

[nolandw]

I am studying in England for a semester. What are some websites to find international travel tickets cheap? I know of sites like studentuniverse.com andcheapoflights.com but I am wondering if there are better alternatives. And from that, what airlines should I avoid?
