The full picture

The data shows an unusually stable fare environment: a $22 median with a floor of $21 and a ceiling of $23. That's a 10% spread, which is low enough that chasing a 'cheap day' isn't a meaningful strategy here — you're more likely to save a dollar or two than any significant amount by timing your purchase perfectly.

Because p25 and p75 both land at $22, the usual booking-window advice (book early for deals, wait for last-minute drops) doesn't really apply on this route in this sample. Short-haul, high-frequency leisure routes like San Francisco to Las Vegas often behave this way — competition and volume keep fares compressed near a baseline rather than swinging with demand cycles the way longer or less-trafficked routes do.

No dominant carrier or weekly pattern is visible in the data provided, so we can't make claims about specific airlines or days of the week driving the price. The honest takeaway: at $22 median with just a $2 range, this route's pricing is remarkably flat, and the sample size of 12 days is thin enough that we'd want more snapshots before treating these numbers as a long-term baseline rather than a snapshot of a particularly stable stretch.
