Ireland has moved from red to orange in the latest EU traffic light travel system.
However, people are still advised not to travel for non-essential purposes.
A new Covid-19 drive-thru testing facility opened at the airport today and a walk in service will open on Monday.
The company behind the first Covid-19 testing centre at Dublin Airport says it has the capacity to deal with passenger demand, when it's needed. It aims to help passengers as part of the EU's new traffic light system for international travel.
