AS 108 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%.

These figures cover 254 flights between July 2025 and June 2026. The median arrival is 11 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 108 flies

AS 108 flies ANC to FAI without a single fixed slot. Its most common scheduled departure was 10:22, used on 95 of 254 flights, with 09:00 (36 flights) and 15:05 (29 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 10:22 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 108 runs 3 points better at 86.6%. 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 108 quarter by quarter

AS 108 did not run the same all year. Its best quarter was Jul–Sep 2025 at 95.7% on time and its weakest Jan–Mar 2026 at 77.5%, a swing of 18 points on roughly 85 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.

Jul–Sep 202592 flights95.7%
Oct–Dec 202591 flights84.4%
Jan–Mar 202671 flights77.5%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, AS 108 ranged from 81.6% on Tuesday to 91.9% on Friday. With about 36 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AS 108 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 2,417 reported delay minutes.

Carrier
39%
Late-arriving aircraft
34%
National Airspace System
15%
Extreme weather
12%

Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 2,417 delay minutes reported on AS 108.

Cancellations are rare at 0.39%, 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

5.5% 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.

Every one of the 254 flights under AS 108 in the data flew ANC to FAI. 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. 254 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 108

For a booking, AS 108 has one of the better records a US domestic flight can show: 86.6% on time and 0.39% cancelled. That is a base rate, not a promise about any single day.
