These figures cover 348 flights between September 2025 and August 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.

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.

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 43 did best on Friday at 92.0% on time and worst on Tuesday at 78.0%. Each day rests on about 50 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

| Date | Arrived late by | Largest filed cause |
|---|---|---|

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 3,007 reported delay minutes.
- 37%Late-arriving aircraft
- 34%Carrier
- 19%Extreme weather
- 9%National Airspace System
- 0%Security
Extreme weather accounts for 19% 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 3.2 times the usual weather exposure. The split is drawn from 3,007 delay minutes reported on AS 43.
Cancellations run at 2.59%, against 1.89% nationally. That is about one flight in 40 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 4.5% 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.
Every one of the 348 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. 348 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: 2.59% of its 348 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
