Eugene to Salt Lake City

What the Data Says About EUG to SLC

The Eugene to Salt Lake City corridor (EUG → SLC) covers roughly 618 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 4,553 flights in the dataset, this route posts a 92.4% on-time rate with an average delay of 107.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,462 flights were recorded on this pairing — 10 cancelled (0.7%) and 3 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,553 total flights analyzed, the 92.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 107.3-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, Sep 2025 posted the best performance on this corridor at 98% on-time, while May 2024 came in at 85% on-time — a 13-point gap between best and worst recent month. For travelers evaluating the EUG to SLC route, the combination of a 92.4% on-time rate, 107.3-minute average delay, 0.7% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
