Qatar Airways has launched a new daily direct service between Dublin and Doha.
A star-studded gala dinner was held at the InterContinental Dublin to mark the occasion on Wednesday.
Among those attending were presenter Kathryn Thomas, rugby star Rob Kearney and models Holly Carpenter and Roz Purcell.
The airline's group chief executive, Akbar Al Baker, said they are committed to bringing more visitors to the capital.
"Dublin has long been on our list of destinations to add to our route map, and I am proud that we are here today to celebrate this important milestone in the history of our airline", he said.
The new route will also give Dubliners connections to more than 150 destinations via Doha.
