These figures cover 320 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.

A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 47 runs 9 points worse at 80.5%. 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 47 quarter by quarter
AS 47 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.9% on time and its weakest Jan–Mar 2026 at 67.4%, a swing of 25 points on roughly 64 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.

By weekday, AS 47 did best on Monday at 91.1% on time and worst on Saturday at 74.4%. Each day rests on about 46 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Share of 318 completed flights by arrival against schedule.
12 of 47 late departures made up the time and arrived on time, 26% of them. In the other direction, 27 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 47
The latest arrival of the period was on 21 March 2026, 5 hours 28 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in March 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 March 2026 | 5 hours 28 minutes | Carrier |
| 4 January 2026 | 4 hours 12 minutes | Carrier |
| 26 February 2026 | 2 hours 28 minutes | Carrier |

Delay causes
Why AS 47 runs late
Carrier accounts for 49% of the 2,884 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 34%National Airspace System
- 8%Extreme weather
- 8%Late-arriving aircraft
- 1%Security
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,401 of the 2,884 delay minutes reported here. The split is drawn from 2,884 delay minutes reported on AS 47.
Cancellations are rare at 0.31%, 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 3.8% 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.
Every one of the 320 flights under AS 47 in the data flew ANC to SEA. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 320 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 47
