Business Class Flights to Dublin

Aer Lingus flies Dublin nonstop from New York, Boston, Chicago, Washington, Philadelphia, Miami, Orlando, Cleveland, Minneapolis, Denver, Las Vegas, Seattle, Los Angeles and San Francisco, with lie-flat business seats on every aircraft including the A321LR and A321XLR narrowbodies. Delta serves Dublin from New York, Boston and Atlanta; United from Newark, Chicago, Washington and San Francisco; American from New York, Philadelphia, Chicago, Charlotte and Dallas; and JetBlue flies Mint from New York and Boston in season. No carrier operates First Class on the route — business is the top cabin on every flight.

The preclearance point is the practical one. On the way home you clear US Customs and Border Protection in Dublin before boarding, which means no immigration queue on arrival, a domestic-terminal landing and a much easier onward connection if you are heading beyond the gateway. Allow an extra hour at Dublin Airport for the preclearance process — the Aer Lingus and Delta lounges sit beyond it.

Dublin works as a base and as a door. Galway and the Cliffs of Moher are two and a half hours by road, Belfast two hours by train, and Aer Lingus's short-haul network reaches London, Edinburgh, Paris and Amsterdam in about an hour — its own Dublin-stopover fares to Europe are worth comparing with a nonstop. St. Patrick's week is the one date to book far ahead or avoid; May through September has the best weather and the highest leisure fares; November through February is grey, atmospheric and cheapest, with business seats from New York at or near our $1,900 starting price.
