Historical statistics for July 2025 to June 2026, not live status. For today’s AS 61, check with Alaska Airlines.

AS 61 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 362 flights, with a median arrival 9 minutes early.

Set against the rest of the country, AS 61's record is 6 points better than the US average of 77.6%. That gap is worth roughly 56 fewer late arrivals for every thousand flights.

These figures cover 362 flights between July 2025 and June 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 61 flies

AS 61 flies SEA to JNU without a single fixed slot. Its most common scheduled departure was 07:00, used on 286 of 362 flights. 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 61 runs 6 points worse at 83.2%. 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 61 quarter by quarter

AS 61 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.0% on time and its weakest Jul–Sep 2025 at 78.0%, a swing of 12 points on roughly 91 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 61 ranged from 76.0% on Monday to 86.8% on Tuesday. With about 52 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AS 61 runs late

One category carries most of the weight here. Carrier accounts for 77% of the 3,380 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.

Carrier
77%
National Airspace System
14%
Late-arriving aircraft
6%
Extreme weather
3%

The largest share of delay minutes, 77%, 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 2,591 of the 3,380 delay minutes reported here. The split is drawn from 3,380 delay minutes reported on AS 61.

Cancellations are rare at 0.28%, 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 4.8% 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 909 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 362 flights under AS 61 in the data flew SEA to JNU. 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. 362 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 61

For a booking, read AS 61 as 83.2% on time with 0.28% cancelled over 362 flights. Those are rates from the past twelve months, not a forecast for any particular day.
