In 2026, the cost of the Paris airport shuttle depends on the specific service used. The RoissyBus, which connects Charles de Gaulle (CDG) to the Opéra district, costs approximately €16.60 for a one-way trip. However, travelers should note that as of March 1, 2026, some direct RoissyBus services are being phased out in favor of the improved RER B train lines and the new Metro Line 14 extension. For those flying into Orly Airport, the OrlyBus to Denfert-Rochereau costs roughly €11.50. Alternatively, the "Le Bus Direct" services that used to be popular have largely been replaced by private shuttle companies and the expanded Metro network. For budget-conscious travelers, local buses 350 and 351 still serve CDG for about €2.15 (or two T+ tickets), though they take significantly longer. In 2026, most visitors find the Metro Line 14 to be the best value for Orly, while the RER B remains the standard for CDG at approximately €11.80.
