Boston–Prague median sits at $343, but sample is thin
Key takeaways
- $343 median fare across the observed snapshots, with a low of $306
- Bottom quartile (p25 = $343) matches the median, suggesting prices cluster near the floor more often than they spike
- Top quartile jumps to $412, meaning roughly a quarter of fares run well above median
- 35% spread between low and high is notable — timing within your search window appears to matter
- Sample size is just 12 days, so treat these figures as a directional signal, not a precise forecast

The full picture
The data shows a $306–$412 range for Boston to Prague fares, with a median of $343 and a 35% spread between low and high. That gap is wide enough to be worth paying attention to — it suggests fares aren't static, and that shoppers who check repeatedly have a real shot at landing closer to the $306–$343 band rather than the $412 ceiling. With p25 equal to the median itself, a meaningful share of observed fares sit at or near the floor, which is a mildly encouraging sign for patient searchers.
We only have 12 days of snapshots here, which is a thin sample for drawing firm conclusions about booking-window timing. We can't responsibly say which weeks or days in advance tend to soften prices, because the data doesn't show a trend over time — it's a snapshot of fare variability, not a longitudinal booking curve. What we can say is that the spread itself (35%) is large enough that casual, one-time searches risk landing in the upper quartile, while comparison-shopping across a few days increases the odds of hitting the $343-or-under range.
No dominant carrier was identifiable from this data, so we can't speak to airline-specific patterns or whether certain operators consistently undercut others on this route. The honest caveat: with only 12 data points, this snapshot could be skewed by a handful of unusual fares, high or low. Treat $343 as a reasonable target rather than a guarantee, and verify with a fresh search before booking, since a sample this size can shift meaningfully with just a few more days of data.
