Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1271, check with Delta Air Lines.
DL 1271 lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 334 flights, with a median arrival 5 minutes early.

These figures cover 334 flights between July 2025 and June 2026. The median arrival is 5 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 1271 flies
DL 1271 flies FLL to ATL without a single fixed slot. Its most common scheduled departure was 12:28, used on 64 of 334 flights, with 12:25 (54 flights) and 12:42 (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 12:28 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 1271 runs level with that at 77.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 1271 quarter by quarter
DL 1271 did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.7% on time and its weakest Jan–Mar 2026 at 65.1%, a swing of 22 points on roughly 84 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 1271 did best on Thursday at 89.4% on time and worst on Sunday at 60.9%. Each day rests on about 48 flights, so a gap of 29 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1271 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 4,666 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.
- 45%Late-arriving aircraft
- 31%Carrier
- 14%National Airspace System
- 10%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,666 reported delay minutes here, that single category outweighs weather by 4 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,666 delay minutes reported on DL 1271.
Cancellations sit at 1.50% against a national 1.81%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
7.3% 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.
The 581 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
DL 1271 is not only a FLL to ATL flight. It also flew ATL to FLL (256 flights, 82.1% 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. 334 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.
