Air France and SNCF open their Train + Air offer to OUIGO trains

Between the rail and the sky, the story has lasted for more than thirty years. Air France and SNCF have long learned how to combine their networks to take travelers to the Parisian runways, without using a car or a domestic flight.

This Thursday, the two partners announced a new chapter. Their joint offer, Train + Air, is open to all OUIGO trains, the low-cost TGVs of the SNCF, which stop at the Paris-Charles de Gaulle airport station.

Environmental virtues

The idea is contained in an image, that of a journey in one piece. A Lyon resident flying to Vancouver can now book their train to Roissy and their plane in one go, with a single ticket, as if it were a simple stopover. Until now, the formula was mainly based on classic TGVs: the INOUI. Unfortunately, only three stations in the South-East, Aix-en-Provence TGV, Avignon TGV and Marseille-Saint-Charles, had access to OUIGO since 2025.

Behind convenience, the company also has an ecological objective in mind. Each passenger who joins Roissy by train rather than by plane reduces their carbon footprint. “Intermodality is one of the pillars of Air France’s decarbonization strategy,” recalls Vincent Etchebehere, director of sustainable development for the company, in a joint press release.

The end of the race against time

It is when the trip gets stuck that the offer reveals all its interest. Anyone who has ever seen their TGV stop in the open countryside, their eyes glued to the boarding time, knows this anxiety. With two tickets purchased separately, a train delay can cost a flight, and the traveler alone pays the consequences. With Train + Air, the risk changes sides. If the train or plane is delayed or canceled, the passenger will be directly placed on the next available departure, without paying an extra euro.

The course is intended to be as light as possible. Check-in is done online on the Air France website, 30 hours before departure, or 24 hours for flights to the United States. The reservation goes through the company's channels or through partner travel agencies.

The formula has clearly found its audience. According to Air France, Train + Air attendance increased by 43% in the first half of 2026 compared to the same period last year. The arrival of OUIGOs, more accessible, could amplify the movement. Jérôme Laffon, general manager of OUIGO, reads this as the response to “a strong expectation from customers for ever simpler and more competitive journeys”.

A card still with holes

The table, however, deserves some touch-ups. The OUIGO network serves more than 70 destinations in France and Europe, but many do not lead directly to Roissy. However, only trains that stop there are eligible for the offer.

In fact, Train + Air only concerns 27 French stations connected to Paris-Charles de Gaulle, according to SNCF. Travelers from Lyon, Bordeaux or Strasbourg will find what they are looking for there, while those from many territories will remain at the dock.

For others, the news feels like a little progress. Guaranteed connections, long reserved for classic TGVs, are becoming accessible at a lower price. One more step towards these trips where rail takes over from short flights, at a time when air travel is required to review its trajectory.
