Big boots to fill: So who would replace Michael O'Leary if he were to retire from Ryanair?
So who would replace Michael O'Leary?
His key lieutenants are now chief marketing officer Kenny Jacobs, chief commercial officer David O'Brien and chief financial officer Neil Sorahan.
O'Leary said yesterday there's a 50:50 chance he will retire in 2019 - when he turns 58.
Michael Hickey is the chief operations officer, and Edward Wilson is the chief people officer. The previous chief financial officer, Howard Millar, stepped down in 2014 to seek fresh challenges.
He remains a board member, however. But he told the Irish Independent before he retired from his executive role, that while he would have liked to run the airline, it was clear Mr O'Leary was staying put: "I came to the realisation that with the new transformed Ryanair that he had just got so enthused about it that in reality he wasn't going anywhere."
