Boston → Edinburgh flights

Boston–Edinburgh fares cluster tight: target the $356–376 window

Key takeaways

• Median fare is $376 across 17 daily snapshots of the cheapest cached fares.
• Bottom-quartile fares start at $356 (p25), meaning roughly a quarter of observed prices came in at or below that level.
• The spread is only 10% ($356 low to $391 high) — an unusually tight range indicating limited price volatility on this route during the sample window.
• The p75 equals the median at $376, suggesting the upper half of fares doesn't climb much — most days landed right around that midpoint.
• Sample size is 17 days, which is a moderate window; treat these figures as directional rather than definitive.

The full picture

The Boston–Edinburgh fare picture right now is notably compressed. Over 17 daily snapshots, the cheapest available fares ranged only from $356 to $391 — a spread of just 10%. That kind of tightness can mean one of two things: either demand and supply are well-matched at the moment and carriers aren't discounting aggressively, or a small number of seats at a promotional price are anchoring the low end. Either way, if you see anything at or below $376, that's at or better than the median — and $356 represents a genuine bottom-quartile value worth acting on.

Because the interquartile range is so narrow (p25 at $356, p75 at $376 — a $20 gap), there's little evidence of meaningful day-to-day swings in this data window. That makes dramatic timing strategies less useful here: waiting for a big dip that isn't apparent in the data could just mean missing a stable fare. Transatlantic routes like BOS–EDI tend to see some softening when booked roughly six to twelve weeks out from departure, but within the current snapshot window there's no directional trend toward lower prices visible — fares appear to be holding flat.

No dominant carrier pattern is identifiable from the data provided, so routing and airline preferences should be guided by schedule and baggage needs rather than an expectation that one carrier will reliably undercut another. One honest caveat: 17 days is a moderate sample, and transatlantic fares can shift materially around school holidays, currency moves, or schedule changes. Treat $356–376 as your credible target range today, and set a fare alert at $360 or below as a conservative trigger to book.
