Aer Lingus cancels flights to US
Aer Lingus has said all flights scheduled to operate between Ireland and New York and Boston on Monday have been cancelled because of Hurricane Irene.
Customers are being informed of the decision by text and email, and can change their travel dates on the airline's website.
Hurricane Irene has made landfall near Cape Lookout, North Carolina, as a weaker but still massive category one storm, US government forecasters said.
As its eye came ashore, Irene packed sustained winds of 140km per hour, the Miami-based National Hurricane Centre said.
After North Carolina, the hurricane was forecast to churn up the eastern seaboard towards Washington, New York and Boston.
The densely populated corridor, home to more than 65 million people, was under threat of flooding, storm surges, power outages and destruction that experts said could cost billions of dollars.
Ports, industries, oil refineries and nuclear plants are scrambling to activate emergency plans while transport systems are preparing to close down.
