Historical statistics for July 2025 to June 2026, not live status. For today’s AS 210, check with Alaska Airlines.

AS 210 lands a B+, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 328 flights, with a median arrival 6 minutes early.

Set against the rest of the country, AS 210's record is 5 points better than the US average of 77.6%. That gap is worth roughly 51 fewer late arrivals for every thousand flights.

These figures cover 328 flights between July 2025 and June 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.

Schedule

When AS 210 flies

AS 210 flies FAI to SEA without a single fixed slot. Its most common scheduled departure was 05:30, used on 84 of 328 flights, with 06:00 (67 flights) and 05:52 (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 05:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 210 runs 7 points worse at 82.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

AS 210 next to FAI to SEA

Across its whole network Alaska Airlines managed 79.1%, which this flight beats by 4 points.

Across the year

AS 210 quarter by quarter

AS 210 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.4% on time and its weakest Jan–Mar 2026 at 71.2%, a swing of 23 points on roughly 82 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 210 did best on Tuesday at 89.6% on time and worst on Sunday at 74.5%. Each day rests on about 47 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 210 runs late

One category carries most of the weight here. Carrier accounts for 61% of the 2,645 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.

Carrier
61%
National Airspace System
34%
Extreme weather
5%

The largest share of delay minutes, 61%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,613 of the 2,645 delay minutes reported here. The split is drawn from 2,645 delay minutes reported on AS 210.

Cancellations sit at 0.91% against a national 1.81%, which is ordinary. Diversions add another 0.30%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.8% 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.

At 1,533 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 328 flights under AS 210 in the data flew FAI to SEA. 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. 328 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 210
