Aer Lingus plans to spend €25 million on a transatlantic business class service that it will launch next March.
The service will be available on all seven of its Airbus A330 on time for its 2015 summer schedule.
It will include a new business lounge at John F Kennedy airport, a new pre-dine service at both the New York hub and Boston airport and a new arrivals lounge in Dublin.
Announcing details of the service at the Royal Hospital Kilmainham, Dublin, yesterday, Aer Lingus chief executive Christoph Mueller said the airline's long-haul business has been growing at record levels over the last two years.
“We continually strive to improve our customers’ Aer Lingus experience offering greater convenience and product enhancements,” he said.
“We have increased the number of destinations to which we fly.
"We have introduced high speed wifi on our services to the US. We clear US customs in Ireland. "
The flights have gone on sale with lead-in fares starting from €899 each way, including taxes and charges.
