These figures cover 323 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.

The latest arrival of the period was on 27 August 2026, 4 hours 13 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across August, July and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 August 2026 | 4 hours 13 minutes | Carrier |
| 17 July 2026 | 3 hours 50 minutes | Late-arriving aircraft |
| 3 July 2026 | 3 hours 33 minutes | Extreme weather |

Delay causes
Why DL 2862 runs late
Carrier accounts for 55% of the 3,873 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 24%Late-arriving aircraft
- 15%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,124 of the 3,873 delay minutes reported here. The split is drawn from 3,873 delay minutes reported on DL 2862.
Cancellations run at 2.79%, against 1.89% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
6.7% 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 761 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 2862 is not only a ATL to OKC flight. It also flew OKC to ATL (308 flights, 81.9% 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. 323 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.
