These figures cover 328 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.

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 82.5%. 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 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 Jul–Sep 2025 at 63.3%, a swing of 31 points on roughly 66 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 89.4% on time and worst on Sunday at 72.3%. Each day rests on about 47 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 210 runs when it is late
AS 210 often beats the schedule: 96 of 325 completed flights, 30%, arrived 15 minutes or more early. Most of the lateness is short. 42 of the 57 late arrivals were under half an hour behind, and 11 reached an hour or more.

Share of 325 completed flights by arrival against schedule.
6 of 29 late departures made up the time and arrived on time, 21% of them. In the other direction, 34 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SEA.
The worst days
Worst days for AS 210
The latest arrival of the period was on 12 December 2025, 5 hours 32 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in December 2025.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 December 2025 | 5 hours 32 minutes | Carrier |
| 29 December 2025 | 4 hours 31 minutes | Carrier |
| 31 May 2026 | 3 hours 6 minutes | Carrier |

Delay causes
Why AS 210 runs late
Carrier accounts for 61% of the 2,840 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Carrier
- 34%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 61%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,745 of the 2,840 delay minutes reported here. The split is drawn from 2,840 delay minutes reported on AS 210.
Cancellations are rare at 0.61%, below the national 1.89% 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
Badly late arrivals are rare here: only 3.4% 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.
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
For a booking, read AS 210 as 82.5% on time with 0.61% cancelled over 328 flights. Those are rates from the past twelve months, not a forecast for any particular day.
