Eugene to San Francisco

What the Data Says About EUG to SFO

The Eugene to San Francisco corridor (EUG → SFO) covers roughly 451 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 5,739 flights in the dataset, this route posts a 83.9% on-time rate with an average delay of 93.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,858 flights were recorded on this pairing — 24 cancelled (1.3%) and 0 diverted (0.0%). 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 5,739 total flights analyzed, the 83.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 93.1-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, Oct 2024 posted the best performance on this corridor at 92% on-time, while Feb 2024 came in at 59% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the EUG to SFO route, the combination of a 83.9% on-time rate, 93.1-minute average delay, 1.3% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
