These figures cover 349 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.
Schedule
When DL 2627 flies
DL 2627 flies ATL to JAX without a single fixed slot. Its most common scheduled departure was 16:45, used on 81 of 349 flights, with 16:25 (59 flights) and 16:47 (51 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 16:45 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2627 runs level with that at 71.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 2627 quarter by quarter
DL 2627 did not run the same all year. Its best quarter was Oct–Dec 2025 at 79.3% on time and its weakest Apr–Jun 2026 at 64.4%, a swing of 15 points on roughly 87 flights a 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.

By weekday, DL 2627 did best on Friday at 82.0% on time and worst on Sunday at 61.7%. Each day rests on about 50 flights, so a gap of 20 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2627 runs late
One category carries most of the weight here. Carrier accounts for 43% of the 4,717 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.
- 43%Carrier
- 28%National Airspace System
- 24%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 43%, 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 2,024 of the 4,717 delay minutes reported here. The split is drawn from 4,717 delay minutes reported on DL 2627.
Cancellations are rare at 0.86%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
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 roughly 50 minutes, which a normal layover absorbs.
DL 2627 is not only a ATL to JAX flight. It also flew JAX to ATL (348 flights, 79.9% 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. 349 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.
