Historical statistics for July 2025 to June 2026, not live status. For today’s DL 875, check with Delta Air Lines.

DL 875 lands a B+, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 260 flights, with a median arrival 16 minutes early.

Set against the rest of the country, DL 875's record is 5 points better than the US average of 77.6%. That gap is worth roughly 54 fewer late arrivals for every thousand flights.

These figures cover 260 flights between July 2025 and June 2026. The median arrival is 16 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When DL 875 flies

DL 875 flies SLC to ATL without a single fixed slot. Its most common scheduled departure was 15:40, used on 57 of 260 flights, with 15:35 (48 flights) and 15:30 (39 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 15:40 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 875 runs 11 points better at 83.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 875 next to SLC to ATL

Every carrier on SLC to ATL combined arrived on time 87.3% of the time across 2,972 flights, so DL 875 is 4 points behind it. Delta flew 2,966 flights on the same city pair under all its flight numbers, including this one, and those ran 87.4% on time. Across its whole network Delta Air Lines managed 81.6%, close to this flight's figure.

Across the year

DL 875 quarter by quarter

DL 875 did not run the same all year. Its best quarter was Jan–Mar 2026 at 87.8% on time and its weakest Jul–Sep 2025 at 77.6%, a swing of 10 points on roughly 87 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 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 875 ranged from 78.4% on Monday to 89.2% on Wednesday. With about 37 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 875 runs late

One category carries most of the weight here. Carrier accounts for 53% of the 2,609 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.

Carrier
53%
Late-arriving aircraft
32%
National Airspace System
15%

The largest share of delay minutes, 53%, 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 1,374 of the 2,609 delay minutes reported here. The split is drawn from 2,609 delay minutes reported on DL 875.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

6.9% 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 an hour, which a normal layover absorbs.

At 1,590 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on one other city pair in the data, including LGA to CVG (88), but none flew often enough under DL 875 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to ATL only.

One caution: this is a thin sample. 260 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.

What to do with this

Booking DL 875

For a booking, read DL 875 as 83.0% on time with 0.00% cancelled over 260 flights. Those are rates from the past twelve months, not a forecast for any particular day.
