Seattle → Los Angeles flights

Fares hover near $29 — but a thin sample means limited confidence

Key takeaways

• The median fare sits at $29, with the bottom quartile (p25) also at $29 — a tight cluster near the low end.
• Prices have ranged from a low of $19 to a high of $41, a spread of 116% relative to the low.
• The p75 of $34 suggests most fares fall between $29 and $34, with occasional spikes above that.
• Only 12 daily snapshots were sampled, so this read should be treated as directional, not definitive.
• No dominant carrier was identifiable from the data, so airline-specific booking patterns can't be claimed here.

The full picture

The data shows a fairly low-cost route overall, with a median fare of $29 and most observed prices clustering between $29 and $34 (the p25–p75 band). The $41 high appears to be an outlier rather than the norm, and the $19 low shows that occasional deep discounts do surface. Given this clustering, treating anything at or below the $29 median as a reasonable fare — and anything near $34 or above as worth waiting on — is a sensible approach based on what we've observed.

We don't have enough snapshots to map a reliable booking-window curve (i.e., how price changes as departure approaches), so we can't responsibly tell you prices soften at a specific number of days out. What we can say is that the spread between low and high (116%) is wide relative to the median, meaning timing does matter here — paying $41 instead of $29 is a meaningful overpay on a route where the typical fare is this low.

No carrier or day-of-week pattern is visible in this dataset, so we won't speculate on which airline or weekday tends to be cheaper. The honest caveat: with only 12 days of snapshots, this is a thin sample for a route as high-frequency as Seattle–LA, and the true price distribution could look different over a longer window. Treat the $29 median as a useful benchmark, not a guarantee.
