A powerful U.S. A Northeast blizzard from Winter Storm Hernando has badly disrupted flights between Ireland and the United States.Winter Storm

What's happening
Winter Storm Hernando is bringing blizzard conditions, strong winds, and heavy snowfall to the U.S. As a result, the Northeast has seen widespread flight cancellations and shutdowns at major hubs. As a result, many Ireland–U.S. flights have been cancelled. The worst-hit services run between Dublin or Shannon and New York, Boston, and Newark. Meanwhile, airlines and airports advise passengers to check flight status and use flexible rebooking. Carriers are working to restore normal schedules when weather allows.
Key points
Storm Hernando has produced up to a metre of snow in parts of the U.S. As a result, the Northeast saw thousands of flight cancellations across the region.
On one day, 13 flights between Dublin and the U.S. were cancelled: seven outbound and six inbound, plus a Shannon–Boston flight.
Also, more flights were cancelled. These included Aer Lingus, Delta, and United services on the Dublin–New York, Dublin–Boston, Dublin–Newark, and Shannon–Boston routes.
Delta Air Lines suspended flights at its hubs in Boston, New York LaGuardia, New York JFK, and Newark through Tuesday. However, disruptions also spread to other Northeast airports.
Still, U.S. carriers say cancellation rates are high but falling. They are preparing to scale up service where conditions allow.
Airlines and Dublin Airport urge passengers to check flight status before travelling. Also, they recommend flexible rebooking and fare-difference waivers when available.
Context and implications
The storm underscores how severe winter weather in the U.S. can rapidly cascade into major disruption for transatlantic networks, even at airports far from the snowfall. Airlines are starting to restore schedules. However, more changes are likely as conditions change. For now, travellers on Ireland–U.S. routes still face uncertainty. Airlines are steering them to online tools and early rebooking during major weather events.
