If I'm looking at on-time stats to see if they should have a bearing on which airline I fly, I care a whole lot about the definition of "on-time." I don't care about being 15-30 minutes late, but I do care about not being 2 hours late.

Again, this sort of thing should be adjusted for routes and airports, but depending on your purpose in flying a route (going home, where your parents will pick you up? flying to LAX to catch an intercontinental flight with a tight connection?), a more granular breakdown is important.

Yeah, it would be cool if they could calculate the "expected minutes late" for every carrier, broken down by route.

You would really need to see the distribution as you can plan for a consistently average delay, but unpredictable arrival can be a real pest.
