Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1058, check with Delta Air Lines.
DL 1058 draws a D. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is roughly 45 minutes behind schedule. Build slack into anything you connect to. That rests on 252 flights, with a median arrival 5 minutes late.
The national on-time rate over the same period is 77.6%, so DL 1058 runs 17 points behind the country as a whole. Across a thousand flights that is about 171 extra late arrivals.

These figures cover 252 flights between July 2025 and June 2026. Beyond the headline rate, 10.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When DL 1058 flies
DL 1058 flies ATL to PBI without a single fixed slot. Its most common scheduled departure was 22:59, used on 40 of 252 flights, with 18:34 (38 flights) and 18:31 (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 22:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1058 runs 10 points worse at 60.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
DL 1058 quarter by quarter
DL 1058 did not run the same all year. Its best quarter was Apr–Jun 2026 at 66.7% on time and its weakest Jan–Mar 2026 at 54.0%, a swing of 13 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.

- Oct–Dec 202511 flights—
- Jan–Mar 202689 flights54.0%
- Apr–Jun 202691 flights66.7%
Scale runs 45% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1058 did best on Wednesday at 83.3% on time and worst on Sunday at 38.9%. Each day rests on about 36 flights, so a gap of 44 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1058 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 4,570 reported delay minutes.
- 41%Carrier
- 36%Late-arriving aircraft
- 21%National Airspace System
- 2%Extreme weather
36% 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 4,570 reported delay minutes here, that single category outweighs weather by 15 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 4,570 delay minutes reported on DL 1058.
Cancellations sit at 1.59% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
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.
The same number turns up on two other city pairs in the data, including JFK to IAH (99) and IAH to JFK (99), but none flew often enough under DL 1058 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to PBI only.
One caution: this is a thin sample. 252 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.
