These figures cover 351 flights between July 2025 and June 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.
Schedule
When DL 2997 flies
DL 2997 flies ATL to SRQ without a single fixed slot. Its most common scheduled departure was 22:30, used on 49 of 351 flights, with 21:35 (36 flights) and 23:05 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 22:30 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2997 runs 9 points better at 79.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
DL 2997 quarter by quarter
Quarter by quarter DL 2997 held fairly steady: 80.0% in Jul–Sep 2025, 81.5% in Oct–Dec 2025, 75.0% in Jan–Mar 2026 and 83.3% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights80.0%
- Oct–Dec 202584 flights81.5%
- Jan–Mar 202690 flights75.0%
- Apr–Jun 202685 flights83.3%
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2997 did best on Tuesday at 85.1% on time and worst on Friday at 72.9%. Each day rests on about 50 flights, so a gap of 12 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2997 runs late
One category carries most of the weight here. Carrier accounts for 59% of the 4,162 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 59%Carrier
- 26%Late-arriving aircraft
- 8%Extreme weather
- 7%National Airspace System
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,462 of the 4,162 delay minutes reported here. The split is drawn from 4,162 delay minutes reported on DL 2997.
Cancellations sit at 2.28% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 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
