These figures cover 365 flights between September 2025 and August 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.

Across the year
DL 1341 quarter by quarter
DL 1341 did not run the same all year. Its best quarter was Apr–Jun 2026 at 78.9% on time and its weakest Jan–Mar 2026 at 66.3%, a swing of 13 points on roughly 91 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.

Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1341 did best on Thursday at 88.5% on time and worst on Sunday at 59.6%. Each day rests on about 52 flights, so a gap of 29 points is worth noticing but could still narrow in another year.

Share of 361 completed flights by arrival against schedule.
15 of 88 late departures made up the time and arrived on time, 17% of them. In the other direction, 22 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 FLL.
The worst days
Worst days for DL 1341
The latest arrival of the period was on 17 March 2026, 5 hours 28 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in December 2025.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 March 2026 | 5 hours 28 minutes | Carrier |
| 7 December 2025 | 3 hours 12 minutes | Late-arriving aircraft |
| 28 December 2025 | 2 hours 50 minutes | National Airspace System |

Delay causes
Why DL 1341 runs late
Carrier accounts for 49% of the 4,629 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 34%National Airspace System
- 16%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,264 of the 4,629 delay minutes reported here. The split is drawn from 4,629 delay minutes reported on DL 1341.
Cancellations are rare at 0.55%, 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
6.1% 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.
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.
DL 1341 is not only a ATL to FLL flight. It also flew FLL to ATL (303 flights, 68.8% 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. 365 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.
