Across the year

DL 2627 quarter by quarter

DL 2627 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.3% on time and its weakest Jul–Sep 2026 at 44.3%, a swing of 39 points on roughly 70 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 Wednesday at 79.2% on time and worst on Monday at 56.9%. Each day rests on about 50 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Share of 345 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 92 departures that left 15 minutes late or more, only 8 made it up before arrival. In the other direction, 24 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at JAX.

Delay causes

Why DL 2627 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,313 reported delay minutes.

Carrier
41%
National Airspace System
32%
Late-arriving aircraft
22%
Extreme weather
4%

32% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,721 minutes out of 5,313, against a national NAS share of 21%. The split is drawn from 5,313 delay minutes reported on DL 2627.

Cancellations are rare at 0.86%, below the national 1.89% 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

8.7% 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 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, 76.8% 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.
