Pictured here are Aer Lingus chief executive Christoph Mueller, US Ambassador to Ireland Kevin O'Malley, and two members of the Aer Lingus cabin crew celebrating the news that Aer Lingus will launch a seasonal service between Dublin and Washington DC as part of its summer schedule.
The service will operate four times a week from next May.
Aer Lingus will also boost its Dublin-San Francisco service to a daily frequency after the route was relaunched by the airline this year.
The airline is also adding a seasonal third daily flight between Dublin and New York, departing the capital just before 8am. Aer Lingus will use a smaller Boeing 757 on the early service.
Mr Mueller said the early departure would enable passengers to visit New York for just a day if they needed to, departing early and leaving on the last flight from New York.
The airline Dublin-Orlando route will operate four times a week for the summer compared to three times weekly this summer.
Long-haul capacity will jump 18.4pc a week during the peak 2015 summer season.
The carrier's chief strategy and planning officer, Stephen Kavanagh, said the extra summer service is targeted at Irish traffic.
