From midnight tonight the EU's traffic light system for travel during the pandemic will take effect.
A new update means red zones requiring passengers to quarantine for 14 days will only be imposed region-by region rather than by country.
People arriving from orange zones can skip quarantine it if they test negative for Covid-19 test three days before arrival.
Eoghan Corry, editor of Air and Travel Magazine, says the system also gives a little more leeway to people making an essential journey.
