These figures cover 357 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 1458 flies
DL 1458 flies ATL to PBI without a single fixed slot. Its most common scheduled departure was 15:17, used on 62 of 357 flights, with 15:33 (47 flights) and 15:42 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

- Departs 15:3347 flights13.2%
- Departs 15:4245 flights12.6%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 15:17 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1458 runs 3 points better at 75.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 1458 quarter by quarter
Quarter by quarter DL 1458 held fairly steady: 77.9% in Jul–Sep 2025, 72.7% in Oct–Dec 2025, 72.7% in Jan–Mar 2026 and 78.9% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 1458 did best on Wednesday at 84.6% on time and worst on Thursday at 60.0%. Each day rests on about 51 flights, so a gap of 25 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1458 runs late
One category carries most of the weight here. Carrier accounts for 44% of the 4,284 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.
- 44%Carrier
- 32%National Airspace System
- 21%Late-arriving aircraft
- 3%Extreme weather
The largest share of delay minutes, 44%, 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 1,898 of the 4,284 delay minutes reported here. The split is drawn from 4,284 delay minutes reported on DL 1458.
Cancellations sit at 1.12% against a national 1.81%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
6.5% 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 50 minutes, which a normal layover absorbs.
The 545 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 1458 is not only a ATL to PBI flight. It also flew PBI to ATL (352 flights, 73.1% 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. 357 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.
