Is there a way to find out if a flight is usually on-time?
 

It seems like I have come across this information in the past, but I can't find it today. Anyone know of a website for this info? It's a NWA flight, but I didn't find anything regarding this at their website.
Thanks for the help!

I use these two regularly:

flightstats.com for processed information.

flightaware.com for raw data. (Register to get more flights into the past).

Thanks! I'll check those sites out. I finally did find one gov site that also helped...
bts.gov

We fly NWA quite often and I find the on time arriveal stats right near the flight info when I am booking online.

I have not seen data on nwa.com. aa.com does have them on some flights.

I haven't looked at NWA in the past couple months so maybe they stopped it but they used to have it.

rkkwan - thanks for the websites - very useful!
