**Industry Context** The renewal of the public service delegation (DSP) for Rennes and Dinard airports marks a significant milestone for regional aviation in Brittany. VINCI Airports, alongside the CCI Ille-et-Vilaine and SEALAR, will continue to manage these platforms under a new mandate that prioritises modernisation, connectivity, and environmental sustainability. This decision reflects a broader trend in the aviation industry where operators are increasingly required to balance economic viability with ambitious decarbonisation targets. **Why This Matters for ATPL and ATC Students** For students training to become airline transport pilots or air traffic controllers, understanding the operational dynamics of regional airports like Rennes and Dinard is crucial. These airports serve as key nodes in the European network, offering direct flights to 15 destinations in 2026, including major hubs like Paris-CDG and Amsterdam-Schiphol. The emphasis on connectivity and modernisation means that future pilots and controllers will encounter enhanced infrastructure and procedures, particularly in areas like approach control, ground handling, and environmental compliance. **Key Developments** The new DSP is structured around four priorities: connectivity, service quality, decarbonisation, and financial autonomy. The 2026 flight schedule already showcases 15 direct destinations operated by eight airlines, with domestic routes to Ajaccio, Bastia, Paris-CDG, Lyon, Marseille, Montpellier, Nice, and Toulouse, and international links to Amsterdam, Dublin, Geneva, London-Gatwick, Manchester, Marrakech, and Seville. Additionally, nearly 200 destinations are accessible via connections through Paris-CDG and Amsterdam, reinforcing Rennes' role as a gateway to Brittany. **Traffic and Freight Dynamics** Traffic at Rennes Bretagne Airport peaked at 856,791 passengers in 2018 but has since stabilised at around 512,000 passengers in 2024 and 2025—a 40% drop from pre-crisis levels. However, the airport recorded over 8,000 commercial movements in 2025, with a load factor of 82% in 2024. In freight, Rennes ranks as the 8th regional platform in France, handling over 10,000 tonnes of cargo in 2024, primarily express shipments to hubs like Cologne/Bonn and Marseille. Dinard Bretagne Airport focuses on general and business aviation, hosting a cluster of aerospace companies that make it an industrial reference point on the Emerald Coast. **Environmental Commitments** VINCI Airports has set ambitious environmental targets: a 50% reduction in CO₂ emissions by 2030 and net-zero carbon by 2050 across its network, with an accelerated target of 2030 for French airports. Measures include energy-efficient building renovations, solar panel installations, LED lighting, and modulation of landing fees based on aircraft emissions. These initiatives align with global aviation sustainability goals and will influence the operational environment for future pilots and controllers. **Conclusion** The renewed DSP for Rennes and Dinard airports represents a strategic investment in regional connectivity and sustainability. For ATPL and ATC students, this development underscores the importance of understanding how regional airports adapt to post-pandemic traffic recovery, environmental regulations, and evolving network strategies. The focus on modernisation and decarbonisation will shape the operational landscape for years to come.
