New Covid testing rules for people coming into Ireland start today.
Earlier this week the Government announced all incoming travellers except those travelling from Northern Ireland will have to present a negative test result in order to enter the country irrespective of the vaccination status.
It followed concerns about the spread of the Omicron variant of Covid-19.
The test requirements were due to be introduced from midnight on Thursday.
However, the system was postponed at the last minute to midnight on Sunday in order to allow airlines prepare for checks.
Those with proof of vaccination can show a negative, professionally administered antigen test carried out no more than 48 hours before arrival or a PCR test taken within 72 hours before arrival.
Those who are unvaccinated must show a negative PCR test result.
Ryanair’s Michael O’Leary had described the move as “nonsense” and “gobbledygook”.
