Across the year
AS 410 quarter by quarter
AS 410 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.3% on time and its weakest Jul–Sep 2026 at 48.3%, a swing of 35 points on roughly 70 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 410 did best on Tuesday at 88.2% on time and worst on Thursday at 54.3%. Each day rests on about 50 flights, so a gap of 34 points is worth noticing but could still narrow in another year.

Share of 346 completed flights by arrival against schedule.
20 of 98 late departures made up the time and arrived on time, 20% of them. In the other direction, 21 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 ORD.
The worst days

The latest arrival of the period was on 11 June 2026, 6 hours 16 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. Three of the five worst days fell in June 2026.

Delay causes
Why AS 410 runs late
National Airspace System accounts for 43% of the 6,654 delay minutes carriers reported here, and the remaining four split what is left.
- 43%National Airspace System
- 36%Carrier
- 19%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,419 of the 6,654 delay minutes reported here. The split is drawn from 6,654 delay minutes reported on AS 410.
Cancellations are rare at 0.85%, 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
11.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 1,721 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.
The same number turns up on one other city pair in the data, including SEA to SFO (5), but none flew often enough under AS 410 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to ORD only.
One caution: this is a thin sample. 352 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 410
For a booking, AS 410 is one of the weaker ways to fly SEA to ORD: 5 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
