Median fares sit at $331 — but thin data makes this a rough guide

Key takeaways

• Median fare of $331 anchors the low end of observed pricing
• 53% spread between low ($331) and high ($508) signals real volatility, not noise
• Bottom quartile (p25) matches the low at $331, suggesting cheap fares cluster at the floor rather than being rare outliers
• Top quartile (p75) hits $508, the same as the high — meaning the upper range is driven by a concentrated set of pricier fares, not scattered spikes
• Only 10 daily snapshots were collected, so this read is a starting signal, not a firm seasonal pattern

The full picture

The data shows a wide gap between IAH–VIE's cheapest and priciest observed fares — $331 at the low end versus $508 at the high, a 53% spread. That's a meaningful range for a transatlantic route, and it tells us fares here aren't stable day to day. Notably, the p25 and low both sit at $331, while p75 and high both land at $508 — with only 10 samples, this likely means the data captured two fairly distinct price tiers rather than a smooth gradient, possibly reflecting different booking windows, fare classes, or even a mix of carriers.

We don't have enough snapshots here to responsibly point to a specific booking window within the horizon where prices typically soften — that kind of claim needs more sustained daily history than the 10 days we have. What we can say is that fares at or near the $331 median do appear repeatedly in the sample, so that figure is a reasonable anchor for what a good deal looks like on this route right now. If you see something close to $331, it's consistent with the lower end of what's been observed; anything approaching $500 is in top-quartile territory and worth comparing against other dates if your travel is flexible.

We don't have visibility into a dominant carrier or specific day-of-week effects from this dataset, so we can't responsibly speak to airline-specific pricing patterns or claim certain departure days are cheaper — that data wasn't present. The honest caveat: a 10-day sample is thin for a route like IAH–VIE, and the stark gap between the two quartiles suggests the true distribution may be more complex than these snapshots show. Treat the $331 median as a useful reference point, but keep checking fares over time rather than assuming this window's pattern will hold.
