Fight Flights

Just found a pretty useful website about flights and airports around the world.

http://www.flightstats.com/go/Home/home.do

Easy to search, handy information on flight status, weather (airport location), airport facilities, travel alerts... you name it.
You can set alert (departure, arrival, default with cancellation, delay etc) to be sent to your email and mobile (to be figured out, may not support carrier other than Americans').
And other information such as frequent flyer program, promotion (haven't checked its updateness and relevancy), published ticket price (maynot be very useful), ratings of airports / airlines / flights, forums of whatever travel topics, etc.
