The full picture

The data here tells a simple story: SEA–IST fares have been remarkably stable, with a median of $305 and a high of just $316 — a spread of only 4%. That's a narrow enough range that calling any particular moment a 'deal' would be a stretch. Prices this consistent usually suggest either a route with limited competitive fluctuation or a snapshot window that didn't capture a major pricing event (holiday surge, fare sale, etc.).

Because the spread is so tight, we can't point to a clear window in the booking horizon where prices reliably soften — there simply isn't enough movement in the data to support that claim. The p25 ($305) and p75 ($309) are nearly identical, meaning even travelers who buy on a 'worse' day within this sample aren't paying much of a penalty. Practically, this means your energy is better spent locking in a fare near the median than trying to game timing.

We also don't have enough signal in this dataset to identify a dominant carrier or a day-of-week effect — nothing in the spread suggests one. One honest caveat: with only 12 daily snapshots, this is a thin sample relative to a full 30-day rolling window, so it may not capture longer-term seasonal swings (e.g., summer peak or holiday pricing on this long-haul route). Treat $305–$316 as a reliable near-term benchmark, not a guarantee of price behavior months out.
