Boston → Las Vegas flights

Boston to Las Vegas fares show a $209 median, but with just 5 snapshots and a 47% spread, treat booking-window guidance cautiously.

BOS–LAS fares cluster near $209 — but sample is too thin to trust

Key takeaways

  • Median fare is $209, with the bottom quartile (p25) essentially the same at $209 — most observed fares sit tightly together.
  • One outlier low of $145 pulls the range down, but it's not reflected in the p25/p75 band, suggesting it was a rare dip rather than a pattern.
  • High of $213 is barely above the median, meaning most days priced within a few dollars of each other — aside from that one low fare.
  • 47% spread looks large, but it's driven almost entirely by that single $145 data point against an otherwise narrow $209–$213 cluster.
  • Only 5 snapshots were collected — far too few to confidently identify booking-window or day-of-week trends.

The full picture

The data shows a surprisingly narrow band for most observed fares — $209 to $213 — with one low outlier at $145 that drags the headline spread up to 47%. That outlier matters: it's the only thing separating this route from a route with almost no price variability at all. If you're budgeting, $209 is the realistic number to anchor on, with hope (but no guarantee) of catching something closer to $145 if you're flexible or lucky.

We can't responsibly say when in the booking horizon prices soften here, because we only have 5 daily snapshots — nowhere near enough to map a reliable curve across weeks or months before departure. Typically this kind of analysis needs 20-30+ days of observations to say anything about early-bird versus last-minute pricing, and this route isn't there yet.

Similarly, no carrier or day-of-week pattern is visible in the data provided — we simply don't have the fields to make that call, and we won't speculate about specific airline pricing behavior without evidence. The honest takeaway: budget around $209, know that a meaningfully cheaper fare has appeared at least once recently, but treat this route's pricing trend as unconfirmed until more data comes in. With a 5-day sample, any claim about *when* to book would be guesswork dressed up as insight — and that's not what we're here to do.
