Bend/Redmond to Seattle

What the Data Says About RDM to SEA

The Bend/Redmond to Seattle corridor (RDM → SEA) covers roughly 228 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 12,501 flights in the dataset, this route posts a 86.8% on-time rate with an average delay of 74.0 minutes when flights run late. Over the most recent 24 months of BTS data, 3,562 flights were recorded on this pairing — 47 cancelled (1.3%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 12,501 total flights analyzed, the 86.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.0-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, Apr 2025 posted the best performance on this corridor at 90% on-time, while Sep 2024 came in at 67% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the RDM to SEA route, the combination of a 86.8% on-time rate, 74.0-minute average delay, 1.3% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
