These figures cover 365 flights between September 2025 and August 2026. The median arrival is 5 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.

A 11:45 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.3%, and DL 316 runs level with that at 80.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 316 quarter by quarter
Quarter by quarter DL 316 held fairly steady: 84.8% in Oct–Dec 2025, 76.1% in Jan–Mar 2026, 80.7% in Apr–Jun 2026 and 83.6% in Jul–Sep 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202592 flights84.8%
- Jan–Mar 202690 flights76.1%
- Apr–Jun 202691 flights80.7%
- Jul–Sep 202662 flights83.6%
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 316 did best on Thursday at 90.2% on time and worst on Saturday at 74.0%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 316 runs when it is late
DL 316 often beats the schedule: 108 of 351 completed flights, 31%, arrived 15 minutes or more early. The 70 late arrivals split 30 under half an hour, 16 between 30 and 60 minutes, and 24 an hour or more.

Share of 351 completed flights by arrival against schedule.
12 of 45 late departures made up the time and arrived on time, 27% of them. In the other direction, 37 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at HNL.
The worst days
Worst days for DL 316
The latest arrival of the period was on 13 February 2026, 20 hours 39 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 February 2026 | 20 hours 39 minutes | Carrier |
| 23 October 2025 | 5 hours 59 minutes | Carrier |
| 26 May 2026 | 4 hours 44 minutes | Carrier |

Delay causes
Why DL 316 runs late
Carrier accounts for 66% of the 5,513 delay minutes carriers reported here, and the remaining four split what is left.
- 66%Carrier
- 22%National Airspace System
- 11%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 66%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,631 of the 5,513 delay minutes reported here. The split is drawn from 5,513 delay minutes reported on DL 316.
Cancellations run at 3.84%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
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 2,994 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 316 in the data flew SLC to HNL. 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 316
For a booking, the cancellation rate is the figure to plan around on DL 316: 3.84% of its 365 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
