These figures cover 331 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 1458 quarter by quarter

DL 1458 did not run the same all year. Its best quarter was Jul–Sep 2025 at 86.7% on time and its weakest Jan–Mar 2026 at 72.7%, a swing of 14 points on roughly 83 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 1458 did best on Saturday at 84.1% on time and worst on Thursday at 60.9%. Each day rests on about 47 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Share of 325 completed flights by arrival against schedule.

12 of 78 late departures made up the time and arrived on time, 15% of them. In the other direction, 17 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 PBI.

Delay causes

Why DL 1458 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 3,912 reported delay minutes.

Carrier
40%
National Airspace System
32%
Late-arriving aircraft
25%
Extreme weather
3%

The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,557 of the 3,912 delay minutes reported here. The split is drawn from 3,912 delay minutes reported on DL 1458.

Cancellations sit at 1.51% against a national 1.89%, which is ordinary. Diversions add another 0.30%.

Connections and routes

What a delay on this flight costs

6.2% 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 45 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.

DL 1458 is not only a ATL to PBI flight. It also flew PBI to ATL (327 flights, 72.5% 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. 331 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.
