These figures cover 265 flights between September 2025 and August 2026. The median arrival is 14 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.

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 2026 at 69.4%, a swing of 18 points on roughly 88 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 875 did best on Wednesday at 89.5% on time and worst on Monday at 74.4%. Each day rests on about 38 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 875
The latest arrival of the period was on 20 July 2026, 16 hours 46 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 July 2026 | 16 hours 46 minutes | Carrier |
| 30 August 2026 | 3 hours 45 minutes | Late-arriving aircraft |
| 16 April 2026 | 2 hours 39 minutes | Carrier |
| 22 April 2026 | 2 hours 31 minutes | Late-arriving aircraft |

Delay causes
Why DL 875 runs late
Carrier accounts for 55% of the 3,634 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 29%Late-arriving aircraft
- 14%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,999 of the 3,634 delay minutes reported here. The split is drawn from 3,634 delay minutes reported on DL 875.
Cancellations are rare at 0.00%, below the national 1.89% 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
6.8% 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 a little over 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. 265 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
