Dublin Airport management has said the famous 'Ath Cliath' sign on Terminal 1 is staying in place.
Mock-ups of new signage have been posted on X showing changes to the outside of both terminal buildings.
Some users grew concerned that the 'Ath Cliath' sign was to be replaced with the word 'DUB' - the international identifier code for the airport.
DAA has since clarified that the Irish signage will be staying in place.
The changes will see the removal of the 'DAA' logo from the buildings with the 'DUB' designator.

Airport coding first began in the 1930s as two-letter codes but by the late 1940s, there were too many airports for the number of two-letter codes available.
The system then shifted to the three-letter codes that are used today.
Los Angeles International Airport, for instance, was originally just 'LA' but became 'LAX' in 1947.
There are over 17,000 possible location codes combinations and approximately 11,300 codes are currently assigned.
