past flight performance data
 

Given flight numbers and dates, where would I go to find scheduled vs. actual departure & arrival information? I'd like to get an idea how frequently a given flight is "on time" (or nearly ontime) over a given sampling period.

Thanks!

Some good souls on the AA forum replied with these addresses to my inquiry about this a while back:
