The managing director of Shannon Airport, Andrew Murphy, is to leave his role.
He will be taking up a position elsewhere in the aviation sector.
Mr Murphy was appointed to the position in January 2017, having previously served as Chief Commercial Officer at Shannon Group, the company responsible for running the state owned airport.
Commenting on his decision, Mary Considine, CEO, Shannon Group said: "Andrew has played an instrumental role at Shannon Group since the early days of its establishment and we are very appreciative of his dedication and hard work throughout his career with us. I would like to wish him every success and happiness in his new career."
Shannon Airport recommenced passenger flights this week, with the resumption of 16 Ryanair services.
Since the on-set of the Covid-19 pandemic, the airport is averaging a 96% drop in passenger numbers.
