These figures cover 302 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.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 82 runs level with that at 87.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

A late pushback is often recovered here: of 26 departures that left 15 minutes late or more, 8 still arrived on time. In the other direction, 18 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.

|---|---|---|
| 21 December 2025 | 3 hours 22 minutes | Carrier |

Delay causes
Why AS 82 runs late
Carrier accounts for 45% of the 1,548 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 43%National Airspace System
- 8%Late-arriving aircraft
- 4%Extreme weather
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 702 of the 1,548 delay minutes reported here. The split is drawn from 1,548 delay minutes reported on AS 82.
Cancellations sit at 1.66% against a national 1.89%, which is ordinary. Diversions add another 0.33%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.7% 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 302 flights under AS 82 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. 302 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.
