These figures cover 314 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.

- 46%Carrier
- 27%National Airspace System
- 25%Late-arriving aircraft
- 3%Extreme weather
The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,003 of the 2,191 delay minutes reported here. The split is drawn from 2,191 delay minutes reported on AS 382.
Cancellations sit at 1.59% against a national 1.89%, 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 2.6% 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 1,978 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. 314 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 382
For a booking, read AS 382 as 81.9% on time with 1.59% cancelled over 314 flights. Those are rates from the past twelve months, not a forecast for any particular day.
