Airline Performance Monitor (APM)
Using data from the Bureau of Transportation Statistics, this code allows you to trivially find out what flights got delayed or cancelled from a given airport or on a given day. For example, in no time at all, you can get the information about all the flights that got delayed from LAX and the factors contributing to those delays or you can get information about all the flights that got cancelled on 5th February, 2011 and so on.
