Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Alaska Airlines.

Alaska on HNL to SLC lands a B+, about a point 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 about an hour on average. That is a workable record, not a spotless one. That rests on 180 flights, with a median arrival right on schedule.

The US average over the same twelve months is 77.6%, 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 180 flights between July 2025 and June 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 180 of the 856 flights on HNL to SLC, about 21% of it. Its 78.8% on time is 4 points worse than the route as a whole, which runs 82.6%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Hawaiian at 85.2% to Alaska at 78.8%. 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.

Departure window

When Alaska runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 13 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is the strongest at 87.7% on time. The full set of windows spans 13 points.

Across the year

Alaska on HNL to SLC through the year

Jan–Mar 202690 flights76.4%
Apr–Jun 202690 flights81.1%

Scale runs 70% to 85%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 78.8% on time across 180 flights.

Split by quarter, Alaska on HNL to SLC logged 90 flights in Jan–Mar 2026 and 90 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 78.8% annual figure is the one to use.

Delay causes

Why Alaska runs late on this route

One category carries most of the weight here. Carrier accounts for 78% of the 2,150 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.

Late-arriving aircraft
10%
National Airspace System
8%
Extreme weather
4%

The largest share of delay minutes, 78%, 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 1,682 of the 2,150 delay minutes reported here. The split is drawn from 2,150 reported delay minutes.

Cancellations are rare at 0.00%, below the national 1.81% 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

6.1% 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 about 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 is a different operation and performs like one: it runs 60.7% on time across 182 flights, 18 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 18 points of difference.

One caution: this is a thin sample. 180 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. 180 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 78.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 179 completed flights over 12 months sit behind that.
