How BOS–DUB gets cheaper

Regional point-of-sale pricing: the same flight is often filed at different tariffs in different countries and currencies.
Split-hub routing: pricing BOS to a competitive hub and that hub to DUB as separate tickets can undercut the nonstop.
Timing: discounted fare buckets typically reopen on a revenue-management schedule; the scan shows the window for this route.
