Air France made this announcement:

For over 25 years, Air France and SNCF French Railways have been offering their customers a service allowing them to combine train and air travel in the same reservation. Called “Train + Air”, it is used every year by more than 160,000 customers to and from Paris-Charles de Gaulle and Paris-Orly airports.

As of today, Air France customers can book a combined “Train + Air” trip on 7 additional routes, for travel as from 19 July 2021:

• between Paris-Charles de Gaulle and Aix-en-Provence TGV, Bordeaux Saint-Jean, Marseille Saint-Charles and Montpellier Saint-Roch;
• between Paris-Orly (via Massy TGV station) and Avignon TGV, Marseille Saint-Charles and Valence TGV.

This extension of this network increases the number of stations offered by Air France as part of the “Train + Air” service to 18: Aix-en-Provence TGV, Angers Saint-Laud, Avignon TGV, Bordeaux Saint-Jean, Champagne-Ardenne TGV, Le Mans, Lille Europe, Lorraine TGV, Lyon Part-Dieu, Marseille Saint-Charles, Montpellier Saint-Roch, Nantes, Nimes, Poitiers, Rennes, Saint-Pierre-des-Corps, Strasbourg and Valence TGV.

Thanks to “Train + Air”, customers have a single reservation for their entire journey and a guaranteed seat on the next available flight or TGV INOUI train, free of charge, if their flight or train arrives late.

As part of the Flying Blue frequent flyer programme, they also earn Miles on the rail leg. In addition, Air France customers travelling in the La Première or Business cabin also travel in first class on SNCF trains.
Digital tests on the CDG and/or Massy TGV – Lille and CDG and/or Massy TGV – Strasbourg routes
To make this combined “Train + Air” journey even simpler, Air France and SNCF are currently testing a new, fully digitalized service, for customers departing from Lille Europe and Strasbourg who have a connection on an Air France flight at Paris-Charles de Gaulle or Paris-Orly.
