How DL875 performs
676 operations, June 2024 – July 2026.
DL875 arrived on time 79.7% of the time, against 85.5% for all SLC → ATL flights, so this departure is 5.8 percentage points worse than the route as a whole. Against Delta Air Lines’ own flights on this route it is 5.9 points worse.

Why DL875 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for DL875 on SLC → ATL. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL875 comes in late, and what that does to the departure.
The aircraft flying DL875 came in 15 or more minutes late on 15% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into SLC just before it, using the tail number in the DOT file, 645 of 674 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| DL875 | 15% |
| Network, same turn | 17% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often DL875’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves SLC late, does that still matter by the time it reaches ATL?
DL875 pushes back an average of 15.6 minutes late and reaches the gate at ATL an average of 1.7 minutes late. The 13.8 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 15.5 minutes on the taxiways at SLC, 2.1 minutes shorter than a typical SLC departure in the same hour.
On arrival at ATL, DL875 spends 11.3 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is 1.7 minutes longer than a typical ATL arrival (9.6 min).
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached ATL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 32,638 departures from SLC scheduled in the clock hour DL875 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at ATL (1,012,161 flights), not just DL875’s own. More on taxi time.

The hour it leaves SLC
Part of any flight’s record belongs to the clock rather than to the flight. DL875 has one departure time, so this is what that time is worth.
On-time arrival rate. 32,638 departures from SLC are scheduled in the 3 PM–4 PM hour over the period, against 355,300 across the whole day.
DL875 is scheduled out of SLC at 3:45 PM, in the 3 PM–4 PM bank. Departures from SLC in that hour arrive on time 83.7% of the time against 84.0% across the airport’s whole day, so the hour DL875 leaves in is an ordinary one for SLC and explains nothing about its record either way.
The two airport figures cover every departure from SLC to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

Because the same number has served different journeys, the statistics above describe only the route DL875 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL875 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 676 records of DL875 operating SLC → ATL, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
