Across the year
AS 626 quarter by quarter
AS 626 did not run the same all year. Its best quarter was Apr–Jun 2026 at 73.6% on time and its weakest Jul–Sep 2026 at 54.1%, a swing of 19 points on roughly 89 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.

- Jan–Mar 202690 flights57.8%
- Apr–Jun 202691 flights73.6%
- Jul–Sep 202661 flights54.1%
Scale runs 45% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, AS 626 did best on Saturday at 76.9% on time and worst on Friday at 43.6%. Each day rests on about 38 flights, so a gap of 33 points is worth noticing but could still narrow in another year.

Share of 266 completed flights by arrival against schedule.
A late pushback is often recovered here: of 124 departures that left 15 minutes late or more, 44 still arrived on time. In the other direction, 20 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.
The worst days
Worst days for AS 626
The latest arrival of the period was on 13 March 2026, 4 hours 24 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On four of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 March 2026 | 4 hours 24 minutes | Late-arriving aircraft |
| 15 July 2026 | 2 hours 44 minutes | Carrier |
| 28 June 2026 | 2 hours 42 minutes | Carrier |
| 4 January 2026 | 2 hours 23 minutes | Carrier |
| 30 May 2026 | 2 hours 11 minutes | Carrier |
Delay causes
Why AS 626 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,891 reported delay minutes.
- 40%Carrier
- 37%Late-arriving aircraft
- 21%National Airspace System
- 2%Extreme weather
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,891 reported delay minutes here, that single category outweighs weather by 21 to one. The split is drawn from 4,891 delay minutes reported on AS 626.
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 routes
What a delay on this flight costs
9.4% 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 same number turns up on one other city pair in the data, including SFO to SEA (48), but none flew often enough under AS 626 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to HNL only.
One caution: this is a thin sample. 266 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 AS 626
For a booking, read AS 626 as 62.4% on time with 0.00% cancelled over 266 flights. Those are rates from the past twelve months, not a forecast for any particular day.
