Carrier by carrier

Hawaiian against every carrier on SEA to HNL

Hawaiian flew 479 of the 2,927 flights on SEA to HNL, about 16% of it. Its 64.9% on time is about level with the route as a whole at 66.2%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Delta at 76.4% to Alaska at 61.7%.

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 76.4% of the time; Alaska Airlines manages 61.7%. Sample sizes sit next to every figure, because a two-point gap across 1,659 flights means less than a ten-point one.

Share of 470 completed flights by arrival against schedule.

A late pushback is often recovered here: of 194 departures that left 15 minutes late or more, 68 still arrived on time. In the other direction, 39 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 HNL.

Delay causes

Why Hawaiian runs late on this route

The largest share of delay minutes, 85%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 14,000 of the 17,000 delay minutes reported here. The split is drawn from 16,549 reported delay minutes.

Cancellations sit at 1.88% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

11.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

At 2,677 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 runs 65.2% on time across 479 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 479 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 Hawaiian on SEA to HNL

Put together: treat all of this as provisional. 479 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 64.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 470 completed flights over 12 months sit behind that.
