Delay causes
Why DL 3093 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,973 reported delay minutes.
- 39%Carrier
- 37%Late-arriving aircraft
- 19%National Airspace System
- 4%Extreme weather
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,973 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 3,973 delay minutes reported on DL 3093.
Cancellations sit at 1.35% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
8.9% 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 about an hour, which a normal layover absorbs.
Every one of the 297 flights under DL 3093 in the data flew ATL to SDF. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 297 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.
