Aer Lingus, Delta, United and other airlines have cancelled flights to New York and Boston due to a major storm moving up the east coast of the US and blizzard warnings for both areas.
US airlines scrapped about 2,000 flights for today and tomorrow and braced for additional cancellations from the winter storm that threatens to dump as much as two feet of snow across parts of New England.
Carriers announcing schedule changes before the arrival of the storm included Delta, United and JetBlue. All three have hubs or bases in the New York area, the busiest US aviation market.
Boston may see 61cm of snow as the coastline is pounded by high waves and wind gusts as high as 80km/h, according to the National Weather Service in the US.
Among the airports most affected by the storm are Newark Liberty International in New Jersey, Logan International in Boston, John F Kennedy International and LaGuardia in New York, and O'Hare International in Chicago, according to industry data tracker FlightStats.com.
Aer Lingus said operations would be impacted today and "to some degree" tomorrow, Saturday. Some flights operated as scheduled today, including flight EI105 to New York.
It said it continued to closely monitor the track of the storm and would update its website with changes to our schedule as they develop.
"Additionally, domestic flight schedules and ground transportation will also be impacted. We recommend contacting your connecting carrier and checking your local news for information."
Those with reservations departing Boston or New York may rebook to travel from Sunday, February 10th through to Wednesday, February 13th at no extra charge.
Passengers have been urged to check the status of their flights prior to departing for the airport.
