These figures cover 282 flights between September 2025 and August 2026. The median arrival is 9 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 682 flies

AS 682 flies SEA to DEN without a single fixed slot. Its most common scheduled departure was 07:05, used on 56 of 282 flights, with 07:30 (42 flights) and 08:30 (34 flights) next.

A 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 682 runs 3 points worse at 86.1%. 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 682 quarter by quarter

AS 682 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.8% on time and its weakest Jul–Sep 2025 at 76.7%, a swing of 16 points on roughly 71 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 682 did best on Sunday at 94.4% on time and worst on Thursday at 75.6%. Each day rests on about 40 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late AS 682 runs when it is late

AS 682 often beats the schedule: 95 of 280 completed flights, 34%, arrived 15 minutes or more early. The 39 late arrivals split 19 under half an hour, 13 between 30 and 60 minutes, and 7 an hour or more.

Share of 280 completed flights by arrival against schedule.

A late pushback is often recovered here: of 33 departures that left 15 minutes late or more, 10 still arrived on time. In the other direction, 16 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 DEN.

Delay causes

Why AS 682 runs late

National Airspace System accounts for 48% of the 1,796 delay minutes carriers reported here, and the remaining four split what is left.

27%
Extreme weather
13%
Late-arriving aircraft
12%

Extreme weather accounts for 13% 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 2.2 times the usual weather exposure. The split is drawn from 1,796 delay minutes reported on AS 682.

Cancellations are rare at 0.71%, 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 2.5% 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.

The 1,024 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.

The same number turns up on two other city pairs in the data, including DEN to SEA (214) and SEA to SMF (70), but none flew often enough under AS 682 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to DEN only.

One caution: this is a thin sample. 282 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 682

For a booking, AS 682 has one of the better records a US domestic flight can show: 86.1% on time and 0.71% cancelled. That is a base rate, not a promise about any single day.
