The number of people who arrived into Dublin Airport rose by nearly 36% last week despite mandatory hotel quarantine for over 50 countries.
Over 21,100 people flew into the facility compared to 15,600 the previous week.
Nearly 12,000 were Irish residents returning from abroad and over 9,200 were non-residents.
Fianna Fáil senator Lisa Chambers says the sharp increase is positive.
She said that people being able to get back out and travelling shows the vaccine programme is working.
