Historical statistics for July 2025 to June 2026, not live status. For today’s AS 682, check with Alaska Airlines.
AS 682 lands a B+, 6 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 about 45 minutes on average. That is a workable record, not a spotless one. That rests on 331 flights, with a median arrival 7 minutes early.
Set against the rest of the country, AS 682's record is 6 points better than the US average of 77.6%. That gap is worth roughly 62 fewer late arrivals for every thousand flights.

These figures cover 331 flights between July 2025 and June 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.
Schedule
When AS 682 flies
AS 682 flies SEA to DEN without a single fixed slot. Its most common scheduled departure was 08:06, used on 56 of 331 flights, with 07:05 (56 flights) and 08:13 (45 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 08:06 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 682 runs level with that at 83.8%. 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 76.9%, a swing of 16 points on roughly 83 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 93.0% on time and worst on Thursday at 68.8%. Each day rests on about 47 flights, so a gap of 24 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 682 runs late
One category carries most of the weight here. National Airspace System accounts for 48% of the 2,384 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.
- 48%National Airspace System
- 26%Carrier
- 13%Late-arriving aircraft
- 13%Extreme weather
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 2.0 times the usual weather exposure. The split is drawn from 2,384 delay minutes reported on AS 682.
Cancellations sit at 0.91% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.0% 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.
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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
AS 682 is not only a SEA to DEN flight. It also flew DEN to SEA (263 flights, 81.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 331 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.
