Boston → Dublin flights

BOS–DUB median is $310 — budget $268–$321 for best odds

Key takeaways

• Median fare is $310, based on 17 daily snapshots of the cheapest cached fares on this route.
• The floor sits at $268 — that's your realistic best-case target, not a guaranteed price.
• 75% of observed fares landed at or below $321, making anything under that figure a solid result.
• The price spread is 22% (low $268 to high $328), indicating moderate volatility — worth monitoring over several days before committing.
• With only 17 data points, treat these ranges as directional guidance rather than a statistically definitive price guarantee.

The full picture

Boston to Dublin is one of the more competitive transatlantic routes, and the fare data reflects that. The $268–$328 observed range is relatively tight for a transatlantic itinerary, with a 22% spread suggesting fares don't swing wildly day to day — but they do move. The median of $310 is a credible planning anchor: if you see something within $10–15 of that, you're in normal territory. If you land below $290, that's a genuine deal worth acting on.

In terms of booking timing, transatlantic routes on the BOS–DUB corridor historically soften when airlines load promotional inventory — typically 6–10 weeks before departure for off-peak travel, or 3–5 months out for peak summer. The data here doesn't tag specific departure dates, so we can't pinpoint a booking-window sweet spot for this snapshot set. What the p25 figure of $268 does tell you is that roughly one in four observed days showed fares at or near the floor — meaning patience and repeated checks over a 1–2 week period could plausibly land you in that range rather than at the median.

No dominant carrier signal emerged from this dataset, so we can't reliably point to one airline as the consistent price leader on this route. The practical upshot: check multiple booking platforms and consider setting a fare alert at $285–$295 — below the median but achievable based on observed lows. One honest caveat: with 17 snapshots rather than a full 30-day window, the statistical picture is moderately thin. These ranges are directional guides, not iron guarantees, and a single schedule change or sale event could shift the floor meaningfully in either direction.
