The wiki doesn't mention some of the newer offerings from www.flightaware.com and www.flightstats.com, both of which are good websites; but both can be time-consuming and sometimes problematic to use if you're surfing on a smart phone while sitting in an airport.

If you have an iPhone, Flight Aware recently released an app that you can find here: http://flightaware.com/news/article/...iPhone-App/113

If you have a Blackberry, I think the mobile version of Flight Stats is best. You can find that here: http://mobile.flightstats.com/go/Mobile/home.do
