AS 268 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.3%. When something does go wrong the average delay runs roughly 40 minutes. That rests on 272 flights, with a median arrival 9 minutes early.

These figures cover 272 flights between September 2025 and August 2026. The median arrival is 9 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.

Schedule
When AS 268 flies
AS 268 flies ANC to SEA without a single fixed slot. Its most common scheduled departure was 05:05, used on 57 of 272 flights, with 06:00 (55 flights) and 16:30 (36 flights) next.

A 05:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 268 runs 3 points worse at 86.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
AS 268 quarter by quarter
AS 268 did not run the same all year. Its best quarter was Oct–Dec 2025 at 91.7% on time and its weakest Jul–Sep 2026 at 75.5%, a swing of 16 points on roughly 68 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.

- Oct–Dec 202560 flights91.7%
- Jan–Mar 202689 flights91.0%
- Apr–Jun 202639 flights82.1%
- Jul–Sep 202654 flights75.5%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 268 did best on Saturday at 94.7% on time and worst on Tuesday at 80.0%. Each day rests on about 39 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 268 runs when it is late
AS 268 often beats the schedule: 99 of 270 completed flights, 37%, arrived 15 minutes or more early. Most of the lateness is short. 20 of the 36 late arrivals were under half an hour behind, and 5 reached an hour or more.

Share of 270 completed flights by arrival against schedule.
A late pushback is often recovered here: of 28 departures that left 15 minutes late or more, 9 still arrived on time. In the other direction, 17 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 268
The latest arrival of the period was on 12 September 2025, 2 hours 10 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 September 2025 | 2 hours 10 minutes | Carrier |
| 17 December 2025 | 1 hour 38 minutes | Carrier |
| 19 March 2026 | 1 hour 36 minutes | Carrier |
| 13 March 2026 | 1 hour 25 minutes | National Airspace System |
| 21 December 2025 | 1 hour 1 minute | Late-arriving aircraft |
Delay causes
Why AS 268 runs late
Carrier accounts for 52% of the 1,387 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 38%National Airspace System
- 10%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 715 of the 1,387 delay minutes reported here. The split is drawn from 1,387 delay minutes reported on AS 268.
Cancellations are rare at 0.74%, 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 routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.9% 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.
The 1,448 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on two other city pairs in the data, including PDX to SNA (28) and ANC to FAI (1), but none flew often enough under AS 268 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ANC to SEA only.
One caution: this is a thin sample. 272 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 268
For a booking, AS 268 has one of the better records a US domestic flight can show: 86.7% on time and 0.74% cancelled. That is a base rate, not a promise about any single day.
