These figures cover 351 flights between September 2025 and August 2026. The median arrival is 6 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.

| 11 August 2026 | 2 hours | Carrier |
| 26 September 2025 | 1 hour 57 minutes | Carrier |

Delay causes
Why DL 2997 runs late
Carrier accounts for 49% of the 3,848 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 36%Late-arriving aircraft
- 11%National Airspace System
- 4%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,848 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 3,848 delay minutes reported on DL 2997.
Cancellations run at 2.56%, against 1.89% nationally. That is about 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
7.9% 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 roughly 50 minutes, which a normal layover absorbs.
Every one of the 351 flights under DL 2997 in the data flew ATL to SRQ. 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. 351 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
Booking DL 2997
For a booking, the cancellation rate is the figure to plan around on DL 2997: 2.56% of its 351 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
