The requirement expired this morning.
Airline passengers heading to the United States no longer need to provide a negative Covid-19 test before departure.
It's after heavy lobbying from airlines and the travel industry.
However, passengers will still need to provide evidence of vaccination.
Eoghan Corry of Air and Travel Magazine, says the requirement had been putting off American tourists who wanted to holiday in Ireland:
“This impacts on large numbers of Irish people going to America but, importantly, the US inbound US market – they are our second biggest tourism market in Ireland – it was a big deterrent for Americans that when they came to Ireland they might fail a test and be stuck here.”
