Dublin Airport has introduced a new rule for passengers travelling to the UK and Ireland from the US.

Passengers arriving from Ireland to Dublin Airport on Sunday will have to check in at the airport’s main gate and then board a plane on the Irish mainland.

The change comes after a number of US-bound flights from Dublin to Los Angeles, Washington DC, San Francisco and New York were delayed on Sunday, after the US President Donald Trump ordered a temporary travel ban on citizens of seven Muslim-majority countries.

The new restriction is in response to a US ban on Syrian refugees from entering the US and a temporary halt on US citizens travelling to several European countries.

Irish airport chief executive Patrick Corrigan told the Irish Independent that the restriction would not affect flights from the UK, which are already exempt from the ban.

“We are not taking this step lightly,” he said.

“The UK and Irish Governments have agreed to work together to provide a seamless flow of visitors to the Republic of Ireland and its surrounding areas, and this restriction is not intended to impact any other countries.”

Mr Corrigan added that the US ban will not affect the flights coming into Dublin.

A Dublin Airport spokeswoman said the new restriction was part of the airport service plans to reduce the number of people who make the journey by sea.

“The Irish Government will not be changing the way people travel to Dublin, and the number who will be subject to the restriction is based on a range of factors, including the number and age of the person travelling, the number, size and age, and destination country,” the spokeswoman said.

In the meantime, there will be a 30-minute wait in Dublin for a ticket, and a 45-minute queue outside the airport.
