Santa Barbara to Seattle

What the Data Says About SBA to SEA

The Santa Barbara to Seattle corridor (SBA → SEA) covers roughly 908 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 2,214 flights in the dataset, this route posts a 85.2% on-time rate with an average delay of 57.7 minutes when flights run late. Over the most recent 24 months of BTS data, 830 flights were recorded on this pairing — 6 cancelled (0.7%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,214 total flights analyzed, the 85.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 57.7-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, Jul 2025 posted the best performance on this corridor at 64% on-time, while Jun 2025 came in at 58% on-time — a 6-point gap between best and worst recent month. For travelers evaluating the SBA to SEA route, the combination of a 85.2% on-time rate, 57.7-minute average delay, 0.7% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
