Historical statistics for July 2025 to June 2026, not live status. For today’s AS 382, check with Alaska Airlines.
AS 382 sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land roughly 40 minutes behind schedule. That rests on 319 flights, with a median arrival 3 minutes early.
The national on-time rate over the same period is 77.6%, so AS 382 runs 4 points behind the country as a whole. Across a thousand flights that is about 44 extra late arrivals.

These figures cover 319 flights between July 2025 and June 2026. The median arrival is 3 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 382 flies
AS 382 flies SEA to BNA without a single fixed slot. Its most common scheduled departure was 17:40, used on 78 of 319 flights, with 17:43 (71 flights) and 23:15 (56 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 17:40 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 382 runs 5 points better at 73.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
AS 382 quarter by quarter
AS 382 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.9% on time and its weakest Jul–Sep 2025 at 48.4%, a swing of 38 points on roughly 80 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 382 ranged from 70.2% on Friday to 77.1% on Monday. With about 46 flights behind each day, a spread of 7 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why AS 382 runs late
One category carries most of the weight here. Carrier accounts for 43% of the 3,470 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.
- 43%Carrier
- 29%Late-arriving aircraft
- 26%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 43%, 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 1,488 of the 3,470 delay minutes reported here. The split is drawn from 3,470 delay minutes reported on AS 382.
Cancellations sit at 1.57% 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 3.8% 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 1,978 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 ANC (19), but none flew often enough under AS 382 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to BNA only.
One caution: this is a thin sample. 319 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
