Historical statistics for July 2025 to June 2026, not live status. For today’s AS 73, check with Alaska Airlines.
AS 73 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 362 flights, with a median arrival 15 minutes early.
Set against the rest of the country, AS 73's record is 10 points better than the US average of 77.6%. That gap is worth roughly 99 fewer late arrivals for every thousand flights.

These figures cover 362 flights between July 2025 and June 2026. The median arrival is 15 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 73 flies
AS 73 flies JNU to ANC without a single fixed slot. Its most common scheduled departure was 07:31, used on 129 of 362 flights, with 07:36 (57 flights) and 07:34 (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 07:31 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 73 runs level with that at 87.5%. 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 73 quarter by quarter
AS 73 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.8% on time and its weakest Jan–Mar 2026 at 70.5%, a swing of 27 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 73 did best on Saturday at 92.2% on time and worst on Monday at 80.0%. Each day rests on about 52 flights, so a gap of 12 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 73 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 3,038 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.
- 44%Late-arriving aircraft
- 24%Extreme weather
- 16%Carrier
- 14%National Airspace System
- 2%Security
Extreme weather accounts for 24% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.8 times the usual weather exposure. The split is drawn from 3,038 delay minutes reported on AS 73.
Cancellations run at 3.04%, against 1.81% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
5.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The 571 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.
AS 73 is not only a JNU to ANC flight. It also flew SIT to JNU (362 flights, 90.5% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
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 73
For a booking, the cancellation rate is the figure to plan around on AS 73: 3.04% of its 362 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
