These figures cover 361 flights between September 2025 and August 2026. The median arrival is 6 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 45 quarter by quarter
AS 45 did not run the same all year. Its best quarter was Jul–Sep 2026 at 86.7% on time and its weakest Jan–Mar 2026 at 75.3%, a swing of 11 points on roughly 90 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.

- Oct–Dec 202590 flights80.7%
- Jan–Mar 202689 flights75.3%
- Apr–Jun 202691 flights85.7%
- Jul–Sep 202661 flights86.7%
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, AS 45 did best on Wednesday at 90.2% on time and worst on Monday at 76.9%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

The worst days
Worst days for AS 45
The latest arrival of the period was on 6 December 2025, 3 hours 35 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 December 2025 | 3 hours 35 minutes | Carrier |
| 27 October 2025 | 2 hours 17 minutes | Late-arriving aircraft |
| 15 June 2026 | 2 hours 10 minutes | Carrier |
| 30 January 2026 | 2 hours 7 minutes | Carrier |
| 20 December 2025 | 1 hour 48 minutes | Late-arriving aircraft |
Delay causes
Why AS 45 runs late
Carrier accounts for 49% of the 2,832 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 36%Late-arriving aircraft
- 8%National Airspace System
- 7%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,832 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 2,832 delay minutes reported on AS 45.
Cancellations run at 3.60%, against 1.89% 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 3.7% 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 361 flights under AS 45 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. 361 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 45
For a booking, the cancellation rate is the figure to plan around on AS 45: 3.60% of its 361 scheduled flights did not operate. A late arrival costs roughly 45 minutes, but a cancellation costs the day, so leave a later option open.
