These figures cover 325 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Delay causes
Why DL 2128 runs late
Late-arriving aircraft accounts for 43% of the 3,661 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 39%Carrier
- 15%National Airspace System
- 2%Security
- 1%Extreme weather
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,661 reported delay minutes here, that single category outweighs weather by 43 to one. The split is drawn from 3,661 delay minutes reported on DL 2128.
Cancellations sit at 1.54% against a national 1.89%, which is ordinary. Diversions add another 0.31%.
Connections and routes
What a delay on this flight costs
6.0% 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.
The 782 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.
DL 2128 is not only a ATL to ICT flight. It also flew ICT to ATL (325 flights, 82.3% 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. 325 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.
