The carrier says it plans to operate all other flights to and from North America.
But it says any passengers planning to travel to or from New York or Newark on Thursday may postpone their travel for up to seven days free-of-charge if they wish to do so.

Passengers will be updated via the company's website, SMS messaging and social media channels.
Aer Lingus has apologised for the disruption "which is due to circumstances beyond our control."
