Delay causes
Why AA 1279 runs late
Late-arriving aircraft accounts for 51% of the 3,975 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 25%Carrier
- 19%National Airspace System
- 5%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,975 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 3,975 delay minutes reported on AA 1279.
Cancellations sit at 2.13% against a national 1.89%, which is ordinary. Diversions add another 0.71%.
Connections and routes
What a delay on this flight costs
8.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The 926 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
AA 1279 is not only a CMH to DFW flight. It also flew DFW to CMH (281 flights, 83.6% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 282 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
