Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Alaska Airlines.
Alaska on HNL to SLC lands a B+, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That rests on 242 flights, with a median arrival right on schedule.
The US average over the same twelve months is 77.3%, so there is little to separate Alaska on HNL to SLC from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on HNL to SLC, 856 flights
These figures cover 242 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Carrier by carrier
Alaska against every carrier on HNL to SLC
Alaska flew 242 of the 856 flights on HNL to SLC, about 28% of it. Its 79.2% on time is 3 points worse than the route as a whole, which runs 82.3%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Delta at 83.8% to Alaska at 79.2%. One 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.

The worst days
Worst days for Alaska on HNL to SLC
The latest arrival of the period was on 4 January 2026, 3 hours 5 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in January 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 January 2026 | 3 hours 5 minutes | Carrier |
| 15 January 2026 | 2 hours 52 minutes | Carrier |
| 24 May 2026 | 2 hours 41 minutes | Carrier |

Delay causes
Why Alaska runs late on this route
Carrier accounts for 73% of the 2,619 delay minutes carriers reported here, and the remaining four split what is left.
- 73%Carrier
- 13%Late-arriving aircraft
- 10%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 73%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,910 of the 2,619 delay minutes reported here. The split is drawn from 2,619 reported delay minutes.
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 stage length
What a delay here costs
5.4% 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 roughly 50 minutes, 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 is a different operation and performs like one: it runs 63.3% on time across 244 flights, 16 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 16 points of difference.
One caution: this is a thin sample. 242 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 Alaska on HNL to SLC
Put together: treat all of this as provisional. 242 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 79.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 240 completed flights over 12 months sit behind that.
