Shannon Airport expects almost 75,000 passengers to pass through its doors between now and New Year's Day.
It will be the airport's busiest Christmas season in three years.
"We know this Christmas will be a special time for many families," said Mary Considine, CEO of the Shannon Airport Group.
"It's wonderful to see passengers arriving home to loved ones or heading off this week, with some experiencing a family gathering for the first time in a few years," she said.
This was the third new route announcement for Shannon in as many weeks, with Ryanair services to Naples and Porto also launching next summer.
"As we look towards the new year, we are delighted to offer 32 destinations from Shannon Airport for 2023," Ms Considine said.
"On behalf of all our team, I would like to wish all our passengers a wonderful Christmas and a happy New Year," she added.
