Historical statistics for July 2025 to June 2026, not live status. For today’s AS 43, check with Alaska Airlines.

AS 43 earns a B−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 346 flights, with a median arrival 7 minutes early.

Set against the rest of the country, AS 43's record is 7 points better than the US average of 77.6%. That gap is worth roughly 65 fewer late arrivals for every thousand flights.

These figures cover 346 flights between July 2025 and June 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.

Schedule

When AS 43 flies

AS 43 flies ANC to BET without a single fixed slot. Its most common scheduled departure was 10:59, used on 84 of 346 flights, with 11:00 (44 flights) and 10:33 (36 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 10:59 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 43 runs level with that at 84.1%. 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 43 quarter by quarter

AS 43 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.2% on time and its weakest Jan–Mar 2026 at 75.0%, a swing of 16 points on roughly 87 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 43 did best on Saturday at 90.4% on time and worst on Monday at 76.0%. Each day rests on about 49 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 43 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,086 reported delay minutes.

Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 3,086 delay minutes reported on AS 43.

Cancellations run at 3.18%, against 1.81% nationally. That is about 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

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.

Every one of the 346 flights under AS 43 in the data flew ANC to BET. 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. 346 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 43

For a booking, the cancellation rate is the figure to plan around on AS 43: 3.18% of its 346 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
