The Aer Lingus Shannon service to New York returns today with a new more fuel efficient aircraft with reduced fuel needs, a quieter engine and cheaper landing charges as a result. 

The A321 Neo LR long range-aircraft, which can carry 186 passengers and crew including 16 business class passengers, resumes service to New York today after a month long winter break in service. 

The service operates six days a week until March 4 when it returns to a daily service, when the year round Boston-Shannon service also goes from a six day to a daily service. 

The new aircraft is 20% more fuel efficient than existing aircraft and has 50% reduced engine noise than the current  A321 CEO, which also means reduced landing charges which are based on noise levels. 

Donal Moriarty, chief corporate affairs officer with Aer Lingus, said the next generation narrow body aircraft will allow it to grow its service across the North Atlantic, and is a core part of the airline's  objectives.

Mary Considine, CEO of Shannon Airport, said the introduction of the new more efficient aircraft on both the New York and Boston routes enables the company to increase its capacity by 20% this year.

This marks the largest increase in the number of Aer Lingus seats out of Shannon in 30 years. 

Ms Considine said they are also hoping that the introduction of the new aircraft with its environmental benefits and cost efficiencies will enable the New York service to become year round from Shannon. 

The grounding of the Boeing 737 MAX aircraft made 2019 an exceptionally challenging year for Shannon.

It lost two services and 120,000 passengers with an equivalent loss of €16m to the Mid-West economy.
