The massive snowfalls from storm Emma have caused travel chaos in Ireland forcing the cancellations of many services, including flights.

Those travelling to Ireland are advised to check with their airlines before going to the airport.

More than 1,900 flights were cancelled to or from British and Irish airports on Friday.

Heathrow, the world's busiest two-runway airport, saw at least 370 departing or arriving flights cancelled, representing around 30 per cent of all scheduled services.

Dublin Airport was forced to close, leading to 342 cancellations but is expected to reopen later today, Australian-time.

"We are preparing for a resumption of flight operations @DublinAirport tomorrow morning," an official tweet. "Some airlines have cancelled services & there may be delays to others."

Emirates cancelled a number of flights between Dublin and Dubai over the past two days.

In a statement, the airline advised customers impacted to "contact their travel agency or the local Emirates office for rebooking."

A Sydney travel agent advised those planning to travel to Ireland from Australia to consider rescheduling their flights or risk delays.

She said to check with the airline or their travel agent before going to the airport.

"If you don't absolutely have to travel, I would reschedule," she said.

"Most of the airlines and being quite understanding in the circumstances."
