New York → Lisbon flights

JFK–LIS median is $273 — the window is tighter than you'd expect

Key takeaways

• Median fare is $273, with the cheapest single observation hitting $258 — a gap of only $15 from floor to midpoint.
• The interquartile range is $260–$282, meaning half of all sampled fares land within a tight $22 band.
• Spread is 20% from low ($258) to high ($309) — modest but not trivial; the top quartile costs roughly $47 more than the bottom.
• Fares below $265 represent a genuine opportunity: they sit in the bottom quartile and are worth acting on quickly when spotted.
• No dominant carrier is identifiable from the data, so comparison-shopping across airlines on any given search is advisable.

The full picture

The 30-day snapshot picture for JFK–LIS is notable for its compression. With a low of $258 and a high of $309, the entire observed range spans just $51 — and the median of $273 sits close to the floor rather than the midpoint. That skew suggests most fares in this window are reasonably competitive, with only occasional spikes toward the $300+ level. Put differently, you're unlikely to find a dramatically cheaper fare by waiting, but you are at real risk of drifting into the upper quartile (above $282) if you delay.

The interquartile range of $260–$282 is the most useful planning anchor here. If a fare you find lands below $265, it's in the bottom quartile of what this data captured — take it seriously. If it's above $282, you're in the top quarter and it may be worth a short wait or a broader search, though the ceiling of $309 suggests the downside of waiting isn't catastrophic. Because the spread is only 20%, this is not a route where surgical timing tends to unlock huge savings; the bigger lever is simply not letting any one fare linger unbooked while prices inch upward.

Carrier-level patterns aren't discernible from this dataset, which means no single airline is visibly undercutting the field consistently. That makes it worth running searches across multiple booking surfaces rather than anchoring to one carrier's schedule. One honest caveat: 30 daily snapshots capture fares at specific moments for specific departure dates; they don't represent the full price distribution across all future travel dates. Seasonal peaks — particularly summer and holiday windows — can push fares well above what this data shows.
