Air France and rail operator SNCF Voyageurs announced a major expansion of their intermodal partnership on 21 September 2026. Effective immediately, every OUIGO high-speed train serving Paris-Charles-de-Gaulle (CDG) joins the ‘Train + Air’ programme, enabling passengers to combine a domestic rail segment and an Air France flight under a single booking code. The move follows a successful 2025 pilot on the Marseille, Avignon and Aix-en-Provence routes and comes after a 43 % surge in Train + Air traffic in the first half of 2026. Under the scheme, travellers check in once, benefit from through-fares, and receive automatic protection onto the next available service if either the train or the flight is delayed. Boarding passes are digital-only, aligning with the airline’s broader push towards paperless travel and lower carbon footprints. For global-mobility teams the expansion unlocks additional same-day rail-to-long-haul connections from key business regions such as Lyon, Strasbourg and Bordeaux, eliminating a domestic feeder flight and simplifying duty-of-care tracking. Employers that mandate low-carbon travel inside France can now book staff on an OUIGO + Air France itinerary without complicated self-ticketing workarounds. The announcement also dovetails with France’s climate law, which bans short-haul domestic flights where a rail alternative of under 2.5 hours exists. By shifting more travellers onto high-speed tracks for the first leg of their journey, Air France reduces its exposure to capacity caps and positions CDG as a greener long-haul hub. Practical tips: Travel managers should update OBTs to display the new combined fares, remind employees that luggage allowances are aligned with the flight segment, and flag that OUIGO trains use separate platforms at CDG’s Terminal 2 station. Early bookings are advised; peak-hour OUIGO seats sell out quickly, and corporate negotiated discounts apply only at the time of initial issuance.
