Since September 24, all Ouigo trains that stop at the Paris-Charles-de-Gaulle airport station have started offering the Train + Air program from Air France. This program allows passengers to combine their train ticket with a flight booking for a discounted rate, making travel between the airport and other destinations more affordable. Ouigo is a low-cost train service operated by the French national rail company SNCF, and it has been expanding its network to provide cheaper travel options for commuters and travelers. The inclusion of the Train + Air program at the major Paris-Charles-de-Gaulle station is a significant step in integrating rail and air travel for passengers. Previously, the Train + Air program was only available at a limited number of stations, which restricted its accessibility for many travelers. Now, with the expansion to all Ouigo trains at the Paris-Charles-de-Gaulle station, more passengers can benefit from the combined ticket offer. This move is expected to increase the use of Ouigo services and encourage more people to use public transport for their travel needs. The program reflects a growing trend in Europe to integrate different modes of transportation to create a more seamless and cost-effective travel experience. By offering combined tickets, companies like Air France and Ouigo aim to make travel more efficient and accessible for passengers who need to move between airports and cities.
