Carrier by carrier

Alaska against every carrier on HNL to SJC

Alaska flew 243 of the 808 flights on HNL to SJC, about 30% of it. Its 72.4% on time is 9 points worse than the route as a whole, which runs 81.4%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Southwest at 88.5% to Alaska at 72.4%. 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 28 points, against half a point between the best and worst carrier.

  • 8am–11am—
  • 11am–2pm210 flights76.2%
  • 2pm–5pm33 flights48.5%
  • 5pm–8pm—
  • 8pm–5am—

Scale runs 40% to 80%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 76.2% 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 210 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 72.4% on time across 243 flights.

Alaska on HNL to SJC did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.6% on time and its weakest Jul–Sep 2026 at 66.1%, a swing of 17 points on roughly 81 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 243 completed flights by arrival against schedule.

20 of 71 late departures made up the time and arrived on time, 28% of them. In the other direction, 16 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 SJC.

Delay causes

Why Alaska runs late on this route

Carrier accounts for 59% of the 3,716 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    59%
  • Late-arriving aircraft
    31%
  • Extreme weather
    5%
  • National Airspace System
    4%
  • Security
    0%

The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,203 of the 3,716 delay minutes reported here. The split is drawn from 3,716 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

8.6% 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 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 84.3% on time across 242 flights, 12 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 12 points of difference.

One caution: this is a thin sample. 243 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. 243 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 72.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 243 completed flights over 12 months sit behind that.
