Historical statistics for July 2025 to June 2026, not live status. For today’s AS 47, check with Alaska Airlines.

AS 47 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 333 flights, with a median arrival 8 minutes early.

These figures cover 333 flights between July 2025 and June 2026. The median arrival is 8 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 47 flies

AS 47 flies ANC to SEA without a single fixed slot. Its most common scheduled departure was 07:05, used on 102 of 333 flights, with 07:00 (80 flights) and 07:15 (50 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 47 runs 9 points worse at 80.1%. 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 83 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 87.0% on time and worst on Wednesday at 74.5%. Each day rests on about 48 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 47 runs late

One category carries most of the weight here. Carrier accounts for 51% of the 3,046 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,544 of the 3,046 delay minutes reported here. The split is drawn from 3,046 delay minutes reported on AS 47.

Cancellations are rare at 0.30%, below the national 1.81% 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 3.9% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 333 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. 333 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

For a booking, AS 47 is one of the weaker ways to fly ANC to SEA: 5 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
