These figures cover 365 flights between July 2025 and June 2026. The median arrival is 13 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 897 flies
DL 897 flies SLC to ATL without a single fixed slot. Its most common scheduled departure was 08:05, used on 109 of 365 flights, with 08:20 (98 flights) and 08:00 (60 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 08:05 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 897 runs 10 points better at 94.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 897 quarter by quarter
Quarter by quarter DL 897 held fairly steady: 93.4% in Jul–Sep 2025, 96.7% in Oct–Dec 2025, 91.1% in Jan–Mar 2026 and 95.6% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights93.4%
- Oct–Dec 202592 flights96.7%
- Jan–Mar 202690 flights91.1%
- Apr–Jun 202691 flights95.6%
Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 897 ranged from 88.5% on Thursday to 98.0% on Monday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 897 runs late
One category carries most of the weight here. Carrier accounts for 67% of the 1,235 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.
- 67%Carrier
- 20%National Airspace System
- 8%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 67%, 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 828 of the 1,235 delay minutes reported here. The split is drawn from 1,235 delay minutes reported on DL 897.
Cancellations are rare at 0.27%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.9% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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.
Every one of the 365 flights under DL 897 in the data flew SLC to ATL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 365 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 897
For a booking, DL 897 has one of the better records a US domestic flight can show: 94.2% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
