Historical statistics for July 2025 to June 2026, not live status. For today’s DL 316, check with Delta Air Lines.

DL 316 lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 6 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 6 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 316 flies

DL 316 flies SLC to HNL without a single fixed slot. Its most common scheduled departure was 12:00, used on 98 of 365 flights, with 11:45 (96 flights) and 10:55 (56 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 12:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, 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: 78.7% in Jul–Sep 2025, 84.8% in Oct–Dec 2025, 76.1% in Jan–Mar 2026 and 80.7% in Apr–Jun 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.

Jul–Sep 202592 flights78.7%
Oct–Dec 202592 flights84.8%
Jan–Mar 202690 flights76.1%
Apr–Jun 202691 flights80.7%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 316 did best on Thursday at 90.4% on time and worst on Saturday at 74.5%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 316 runs late

One category carries most of the weight here. Carrier accounts for 65% of the 5,769 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.

11%
Extreme weather
0%

The largest share of delay minutes, 65%, 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 3,734 of the 5,769 delay minutes reported here. The split is drawn from 5,769 delay minutes reported on DL 316.

Cancellations sit at 1.92% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

7.0% 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 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, read DL 316 as 80.1% on time with 1.92% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
