Washington → Dublin flights

Target $416–$441 for Washington–Dublin flights

Key takeaways

• Median fare is $441 across 30 daily snapshots of the cheapest cached fares on this route.
• Bottom-quartile fares dip to $416 or below — that's your realistic target if you have flexibility to wait or compare.
• The floor recorded was $346, but at the 46% spread between low and high ($505), that low is an outlier rather than a reliable benchmark.
• A $159 gap separates the cheapest and most expensive fares observed, meaning timing and flexibility meaningfully affect what you pay.
• The p25–p75 range of $416–$492 is the band where most competitive fares cluster — budget within this window to avoid surprises.

The full picture

Washington Dulles and Reagan National routes to Dublin have historically attracted competitive transatlantic pricing, and this 30-snapshot dataset reflects that. With a median of $441 and a bottom quartile at $416, the realistic "good deal" threshold sits roughly $25–$90 below the midpoint — achievable but not guaranteed on any given search. The 46% spread between the absolute low ($346) and high ($505) is notable: it signals that fares on this route move meaningfully, so passive monitoring pays off more than booking the first price you see.

On transatlantic routes generally, fares tend to soften in two windows: roughly 2–4 months before departure for summer travel, and 4–6 weeks out when unsold inventory reappears at reduced prices. This dataset doesn't tag fares by how far in advance they were captured, so we can't confirm that pattern here specifically — but it's consistent with how yield management works on long-haul leisure routes. What the data does suggest is that fares cluster tightly between $416 and $492 for a large portion of observations, meaning extended patience beyond that p25 threshold may not yield dramatic additional savings.

Carrier concentration isn't visible in this dataset, so route-specific airline advice isn't warranted. One honest caveat: 30 snapshots represent the cheapest available fare on each day sampled, not a complete picture of seat availability or booking-class depth. A $346 fare appearing in the data doesn't mean seats at that price will be accessible when you search — it means it was the lowest cached price on at least one day. Use the $416–$441 range as your planning anchor, and treat anything below $400 as a genuine opportunity worth booking promptly.
