These figures cover 349 flights between September 2025 and August 2026. The median arrival is 8 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 June 2026 | 3 hours 40 minutes | Carrier |
| 16 July 2026 | 2 hours 36 minutes | Extreme weather |

Delay causes
Why OO 3802 runs late
Carrier accounts for 49% of the 2,997 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 41%Extreme weather
- 9%National Airspace System
- 1%Security
Extreme weather accounts for 41% 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 6.7 times the usual weather exposure. The split is drawn from 2,997 delay minutes reported on OO 3802.
Cancellations are rare at 0.86%, 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
5.5% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
OO 3802 is not only a PDX to SEA flight. It also flew SEA to PDX (349 flights, 85.0% 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. 349 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.
