Chief executive Amanda McMillan is to leave AGS Airports and relocate to Australia.
McMillan, who has been managing director of Glasgow airport for nine years, will continue in her role until early next year.
AGS Airports group also operates Aberdeen and Southampton airports.
Chairman Sir Peter Mason said: “On behalf of the AGS Board, I would like to convey our sincere thanks to Amanda for the outstanding job she has done in establishing the AGS Airports Ltd group since its creation in 2014.
“Through her distinctive brand of leadership, AGS has become one of the UK’s leading airport groups. During this period, our airports in Aberdeen, Glasgow and Southampton have benefited hugely from her drive and commitment to continually improve the customer experience for our growing number of passengers.
McMillan added: “It is with mixed emotions that I am planning to move on, but this opportunity is one that comes at the right time for us as a family. I am immensely proud of the team at AGS which has delivered significant passenger growth, secured new carriers, built enviable destination lists and completed a series of first-class modernisation projects.”
