These figures cover 233 flights between September 2025 and August 2026. The median arrival is 13 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.

Departure window

When Alaska runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 233 flights.

There are not enough flights in each departure window to split Alaska's SFO to LIH record by time of day without the percentages moving on noise. The headline rate of 90.0% is the reliable figure here.

Delay causes

Why Alaska runs late on this route

Carrier accounts for 63% of the 1,091 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    63%
  • National Airspace System
    30%
  • Late-arriving aircraft
    6%

The largest share of delay minutes, 63%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 691 of the 1,091 delay minutes reported here. The split is drawn from 1,091 reported delay minutes.

Cancellations are rare at 0.43%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 1.7% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 2,446 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 71.0% on time across 234 flights, 19 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 19 points of difference.

One caution: this is a thin sample. 233 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 SFO to LIH

Put together: treat all of this as provisional. 233 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 90.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 231 completed flights over 12 months sit behind that.
