First Aviation managing director and Monarch Airlines director Alan Murray is to leave the group at the end of October.
Murray, a director of the airline for seven years, will leave the group on October 31 “having earlier expressed his desire to do so,” according to the Monarch group.
The process for appointing a new head of the charter division was described as “progressing well”. A further announcement will be made in due course, the company said.
In the interim, Murray’s responsibilities will be assumed on an interim basis by a management group including Monarch Airlines managing director Tim Jeans, airline operations managing director Kevin George and First Avaiation director and general manager John Romo.
“The charter business is a centrepiece of the Monarch group’s strategy in its travel and aviation operations,” a statement said.
“The group looks forward to the further development of this core business from its current base of flying some 2.5 million sector passengers to over 50 mid and long-haul destinations annually.”
The group reported “sound trading” across all businesses over the summer, with record load factors on Monarch flights and improved operating margins.
Monarch recently announced a widespread restructuring of its activities and governance structures, following a review started at the beginning of the year.
This led to the management team being strengthened by new appointments including Simon Tucker as group finance director and Richard Hadfield as managing director of retail and online activities.
The restructuring of group divisions saw Hugh Morgan return to the UK as managing director of group tour operations, Stuart Jackson promoted to group distribution director and the appointment of Kevin George and Richard Mintern as chief operating officer.
