These figures cover 492 flights between September 2025 and August 2026. The median arrival is 8 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.

Carrier by carrier
Delta against every carrier on HNL to SLC
Delta flew 492 of the 856 flights on HNL to SLC, most of the route. Its 83.8% on time is 2 points better than the route as a whole, which runs 82.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Delta at 83.8% to Alaska at 79.2%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Across the year
Delta on HNL to SLC through the year
December is the weak month at 74.1% on time, against 96.8% in October. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 60 flights.
Across the week, Wednesday is the strongest day at 94.8% on time and Saturday the weakest at 78.1%, a spread of 17 points.

Share of 475 completed flights by arrival against schedule.
13 of 56 late departures made up the time and arrived on time, 23% of them. In the other direction, 34 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 SLC.
The worst days
Worst days for Delta on HNL to SLC
The latest arrival of the period was on 14 February 2026, 15 hours 4 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 |
|---|---|---|
| 14 February 2026 | 15 hours 4 minutes | Carrier |
| 14 December 2025 | 6 hours 42 minutes | Late-arriving aircraft |
| 27 June 2026 | 4 hours 1 minute | Late-arriving aircraft |

Delay causes
Why Delta runs late on this route
Carrier accounts for 53% of the 5,532 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 32%Late-arriving aircraft
- 16%National Airspace System
The largest share of delay minutes, 53%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,918 of the 5,532 delay minutes reported here. The split is drawn from 5,532 reported delay minutes.
Cancellations run at 3.05%, against 1.89% nationally. That is roughly one flight in 30 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 stage length
What a delay here costs
5.3% 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.
The return leg runs 80.9% on time across 492 flights, within 3 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 492 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 Delta on HNL to SLC
Put together: the delay figures matter less here than the 3.05% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5pm–8pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 475 completed flights over 12 months sit behind that.
