Business Class to Dublin

Through a consolidator, Business Class to Dublin is roughly $2,300-2,900 round-trip from Boston, $2,400-3,000 from New York, and $2,500-3,200 from Chicago or Washington, all on lie-flat Aer Lingus or United Polaris cabins, 30-60% below the published fare.

Aer Lingus is the specialist: it has the most US-Dublin gateways and a lie-flat 1-2-1 A330 Business cabin at the best price. United Polaris (from Washington and Chicago) and Delta One also serve Dublin and are strong alternatives on those routes.
