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

Alaska on HNL to SJC sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 181 flights, with a median arrival 1 minute early.

The US average over the same twelve months is 77.6%, so there is little to separate Alaska on HNL to SJC 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 SJC, 809 flights

These figures cover 181 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 SJC

Alaska flew 181 of the 809 flights on HNL to SJC, about 22% of it. Its 74.6% on time is 9 points worse than the route as a whole, which runs 83.5%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Southwest at 89.0% to Alaska at 74.6%. 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 32 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am
  • 8am–11am
  • 11am–2pm148 flights80.4%
  • 2pm–5pm33 flights48.5%
  • 5pm–8pm
  • 8pm–5am

Scale runs 40% to 85%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 80.4% on time, ahead of 2pm–5pm at 48.5%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 148 flights scheduled in it.

Across the year

Alaska on HNL to SJC through the year

  • Jan–Mar 202689 flights66.3%
  • Apr–Jun 202692 flights82.6%

Scale runs 60% to 90%. 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 74.6% on time across 181 flights.

Split by quarter, Alaska on HNL to SJC logged 89 flights in Jan–Mar 2026 and 92 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 74.6% 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 66% of the 2,732 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.

  • Carrier
    66%
  • Late-arriving aircraft
    24%
  • Extreme weather
    6%
  • National Airspace System
    5%
  • Security
    0%

The largest share of delay minutes, 66%, 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 1,790 of the 2,732 delay minutes reported here. The split is drawn from 2,732 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

7.7% 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 2,417 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 91.1% on time across 180 flights, 17 points above 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 17 points of difference.

One caution: this is a thin sample. 181 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 SJC

Put together: treat all of this as provisional. 181 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 74.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 181 completed flights over 12 months sit behind that.
