These figures cover 267 flights between September 2025 and August 2026. The median arrival is 7 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 21:40 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.1%, and AS 206 runs 10 points better at 79.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
AS 206 quarter by quarter
Quarter by quarter AS 206 held fairly steady: 74.7% in Jan–Mar 2026, 84.6% in Apr–Jun 2026 and 79.7% in Jul–Sep 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Jan–Mar 202689 flights74.7%
- Apr–Jun 202691 flights84.6%
- Jul–Sep 202662 flights79.7%
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, AS 206 did best on Tuesday at 91.7% on time and worst on Friday at 64.9%. Each day rests on about 38 flights, so a gap of 27 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 206 runs when it is late
AS 206 often beats the schedule: 89 of 259 completed flights, 34%, arrived 15 minutes or more early. Most of the lateness is short. 26 of the 52 late arrivals were under half an hour behind, and 11 reached an hour or more.

Share of 259 completed flights by arrival against schedule.
A late pushback is often recovered here: of 65 departures that left 15 minutes late or more, 26 still arrived on time. In the other direction, 13 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 SEA.
The worst days
Worst days for AS 206
The latest arrival of the period was on 20 July 2026, 2 hours 48 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 July 2026 | 2 hours 48 minutes | Late-arriving aircraft |
| 29 March 2026 | 2 hours 32 minutes | Late-arriving aircraft |
| 19 February 2026 | 1 hour 52 minutes | Late-arriving aircraft |
| 14 March 2026 | 1 hour 51 minutes | Carrier |
| 1 May 2026 | 1 hour 39 minutes | National Airspace System |
Delay causes
Why AS 206 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 2,256 reported delay minutes.
- 42%Late-arriving aircraft
- 23%National Airspace System
- 18%Carrier
- 17%Extreme weather
- 1%Security
Extreme weather accounts for 17% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.8 times the usual weather exposure. The split is drawn from 2,256 delay minutes reported on AS 206.
Cancellations sit at 1.87% against a national 1.89%, which is ordinary. Diversions add another 1.12%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.2% 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 2,639 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 PDX to ABQ (7), but none flew often enough under AS 206 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to OGG to SEA only.
One caution: this is a thin sample. 267 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 206
For a booking, read AS 206 as 79.9% on time with 1.87% cancelled over 267 flights. Those are rates from the past twelve months, not a forecast for any particular day.
