The full picture

Fares between Seattle and GIG have ranged from $537 to $633 over our 12-day sample, with a median of $544. That's an 18% spread — not razor-tight, but not the kind of wild swing that rewards aggressive timing games either. The bulk of observed fares cluster near the low end: the 25th percentile matches the floor at $537, meaning most snapshots we captured came in cheap, while the top quartile stretches up to $633. In practice, this suggests the $544 median is a fair expectation for planning, with some upside risk if you book during a pricier window.

We don't have enough longitudinal data here to say when in the booking horizon (e.g., 2 weeks out vs. 2 months out) prices typically soften — our snapshots capture a 12-day cross-section of cached fares, not a full booking-curve history. What we can say is that the narrow gap between the median and the 25th percentile indicates fares don't frequently dip far below $537 in this dataset, so waiting for a dramatic discount may not pay off. If you see something at or near $537, that's effectively the floor we've observed.

No dominant carrier was identifiable from the data, and we can't speak to day-of-week patterns with confidence given the sample size. The honest caveat: 12 days is a thin sample for a route like this, especially one involving a long-haul international leg to Rio de Janeiro. Treat the $544 median as a useful benchmark, but expect some noise — book when you see a fare at or below the median rather than waiting for a specific day-of-week signal that this data doesn't support.
