San Francisco to Eugene

What the Data Says About SFO to EUG

The San Francisco to Eugene corridor (SFO → EUG) covers roughly 451 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 5,745 flights in the dataset, this route posts a 85.2% on-time rate with an average delay of 76.8 minutes when flights run late. Over the most recent 24 months of BTS data, 1,858 flights were recorded on this pairing — 21 cancelled (1.1%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,745 total flights analyzed, the 85.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.8-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Jan 2025 posted the best performance on this corridor at 90% on-time, while Jul 2024 came in at 73% on-time — a 17-point gap between best and worst recent month. For travelers evaluating the SFO to EUG route, the combination of a 85.2% on-time rate, 76.8-minute average delay, 1.1% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
