Since the direct Roissybus line was discontinued on March 1, 2026, there aren’t many options for getting to Roissy airport from Paris. The RER B remains the obvious choice, with a journey time of about 35 to 40 minutes from Châtelet. Another option? Jump on bus 9517, which connects Roissy-Paris-Charles de Gaulle from Argenteuil via Saint-Denis-Pleyel. Looking ahead to 2030, it will also be possible to reach Roissy from the capital by taking the future line 17 of the Grand Paris Express.
In the meantime, Parisians and visitors will have a new service to count on: the CDG Express. With a launch date set for March 28, 2027, the future CDG Express line will link directly from Paris-Est station to Paris-Charles de Gaulle Airport, Terminal 2, in just 20 minutes, with no intermediate stops. To ease travel for French and international passengers, the CDG Express will run every 15 minutes from 5 a.m. to midnight, and will connect with the RER B, D and E, the metro (lines 2, 4, 5 and 7), the Transilien network (lines H, K and P), and several bus lines.
But what about the fares? How much will a ticket cost to reach Roissy airport from Paris by taking the CDG Express? At a press conference held on May 27, Hello Paris, operator of the CDG Express line, unveiled this upcoming service as well as the trains for the new link. It was an opportunity to learn more about the grille tarifaire.
For a round trip aboard the CDG Express, you’ll need to shell out 42.50 euros if you’re a casual traveler. The one-way fare is set at 25 euros. Navigo pass holders can, on their side, benefit from an approximate 35% discount, paying 16.50 euros for a one-way or 28 euros for a round trip. Hello Paris, meanwhile, announces free travel for children under 16 who are accompanied. Regarding employees of the airport platform, a preferential subscription will be offered, with a price still to be defined. A family ticket (2 adults, 2 children) will also be offered at 33 euros. Finally, tickets will be sold at station kiosks, online, and via a mobile app.
