JFK–SJU fares cluster tight around $120 — book anytime
Key takeaways
- Median fare is $120, with 50% of observed prices falling between $117 and $121 — an unusually narrow band.
- The lowest recorded fare was $110, only $10 below the median, so dramatic dips are rare in this dataset.
- Spread is just 11% — below our 15% threshold — meaning this route shows limited price volatility across the 18-day window.
- The high was $122, barely above median, so there's little evidence of price spikes to actively avoid.
- With fares this compressed, the main opportunity is catching the occasional sub-$115 outlier rather than timing the market.

The full picture
The JFK–San Juan corridor is showing an unusually flat pricing structure right now. Across 18 daily snapshots, the cheapest available fares ranged from $110 to $122 — a spread of just 11%, which falls below the threshold we'd typically associate with meaningful booking-window strategy. The interquartile range of $117–$121 reinforces this: three-quarters of observed prices are packed into a $4 band. On a route with this kind of compression, the conventional wisdom about "booking at the right moment" has limited practical value.
That said, the floor of $110 does appear occasionally, and if you see a fare at or below $115, that represents genuine outperformance versus the median. There's no evidence in this data of a specific booking horizon where prices reliably soften — the flatness suggests either steady demand on this leisure route or consistent competitive pricing among carriers operating JFK–SJU. Without carrier-level data, we can't attribute this to any one airline's pricing strategy, but the Puerto Rico corridor is typically served by multiple competitors, which likely contributes to the stability.
One honest caveat: 18 snapshots is a thinner sample than the 30 we'd prefer, which means episodic fare drops or spikes could be underrepresented here. This data reflects cached cheapest fares at the time of capture and may not account for seat availability changes or holiday-period surges. Treat $120 as a reliable baseline, but check back if your travel dates shift toward peak season.
