These figures cover 364 flights between September 2025 and August 2026. The median arrival is 4 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.

Across the year
DL 2945 quarter by quarter

The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

|---|---|---|
| 9 December 2025 | 10 hours 25 minutes | Extreme weather |
| 14 June 2026 | 3 hours 15 minutes | Carrier |
| 3 July 2026 | 2 hours 54 minutes | Late-arriving aircraft |

Delay causes
Why DL 2945 runs late
Carrier accounts for 45% of the 4,432 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 25%Late-arriving aircraft
- 16%Extreme weather
- 14%National Airspace System
Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.7 times the usual weather exposure. The split is drawn from 4,432 delay minutes reported on DL 2945.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 0.82%.
Connections and routes
What a delay on this flight costs
5.9% 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.
The 765 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.
Every one of the 364 flights under DL 2945 in the data flew ATL to ATW. 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. 364 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.
What to do with this
