**A new captain for the Dubreuil airline group** The Dubreuil Group, the family-owned conglomerate behind Air Caraïbes, Air Caraïbes Atlantique, French bee, and Hi Line Cargo, has appointed Géry Mortreux as the head of its aviation division. Mortreux, a 60-year-old engineer and former Executive Vice President of Air France Industries KLM Engineering & Maintenance, will officially take up his role on 15 July 2026. The announcement, made on 9 June 2026, ends an 18-month interim period during which group CEO Paul-Henri Dubreuil directly managed the airlines after the departure of long-time leader Marc Rochet. **A career rooted in maintenance and operations** Mortreux brings a deeply operational background to the position. A graduate of ENSMA (École Nationale Supérieure de Mécanique et d'Aérotechnique) and holder of an Executive MBA from HEC Paris, he began his career in 1989 as a maintenance engineer at Air Inter. He later held senior roles at Air France, Sabena Technics, and Corsair, where he served as Chief Operating Officer and accountable manager. At Air France Industries, he oversaw one of the world's largest MRO (maintenance, repair, and overhaul) organisations, managing thousands of technicians and complex supply chains for Airbus and Boeing fleets. **Why this matters for the Dubreuil airlines** The appointment signals a strategic focus on industrial efficiency and cost control. Air Caraïbes, which carried over 1.5 million passengers in 2023 and generates around €600 million in revenue, operates a dense network from Paris-Orly to the French Caribbean and South America. French bee, the low-cost long-haul arm, flies an all-A350 fleet to destinations including Réunion, Tahiti, New York, San Francisco, Los Angeles, Miami, and Montréal. Both carriers face intense pressure on fuel costs, environmental regulations, and fleet availability. Mortreux's MRO expertise is expected to improve aircraft dispatch reliability, reduce maintenance turnaround times, and optimise spare parts inventory — all critical for seasonal, long-haul operations where a single delay can cascade across the network. **Broader industry context** This appointment reflects a growing trend in aviation: placing leaders with deep technical and operational experience at the helm of airlines, rather than purely commercial or financial backgrounds. For ATPL and ATC students, it underscores the importance of understanding MRO economics, fleet planning, and the operational constraints that shape an airline's strategy. The ability to communicate with engineers, anticipate maintenance bottlenecks, and manage cost drivers is increasingly valued in senior management roles. The Dubreuil Group's choice also highlights how family-owned carriers can leverage niche strengths — in this case, a homogeneous A350 fleet and strong regional brand loyalty — to compete against larger groups. **Looking ahead** Paul-Henri Dubreuil will remain involved in the aviation division, working alongside Mortreux to ensure continuity. The group's cargo arm, Hi Line Cargo, adds another layer of complexity, as freight markets remain volatile post-pandemic. For students tracking airline management, this case offers a real-world example of how leadership transitions, MRO strategy, and network planning intersect in a competitive, regulation-heavy environment.
