Continental currently operate a daily year round service from Shannon to its Newark hub and from there a wide range of connecting flights throughout the U.S.
The additional services, commencing May 28 and lasting until the September 8, will operate on Tuesdays, Wednesdays, Fridays and Sundays with a departure time of 1.15 p.m. in the afternoon.
All Continental Airlines services will use the airport's full U.S. pre-clearance customs and immigration facility.
"This is a significant boost for Shannon Airport and we are delighted to have this additional capacity in the transatlantic market this summer. In this challenging business environment, Continental Airlines' decision shows the continued appeal of Shannon and the West of Ireland for doing business," said airport director, Martin Moroney.
"Continental Airlines has been a strong performer at Shannon since it commenced services here in 1998. It has successfully built a year-round customer base in the West of Ireland in the business and leisure sectors. This announcement is proof that Continental Airlines see further opportunities for growth at Shannon and we look forward to working closely with them on delivering those extra passengers," he said.
