IDFM says "60 à 80 minutes"; the timetable schedules 44 to 76. It is the all-stops road route through Le Bourget, and traffic decides the rest.

It stops at Terminal 1 on the way out of the airport, which the 9517 and the 351 do not.

The EUR 14 airport ticket is not valid on it.

Take a train signed for Saint-Rémy-lès-Chevreuse or Massy-Palaiseau: only those call at Antony, where you change for the Orlyval. Trains for Robinson, and those that end in central Paris, do not.

Orlyval puts the whole trip at 1 hour 15 minutes on average, change included; the two rides alone are about an hour and ten minutes.

Orlyval runs every day 06:00 to 23:35. The RER B leg decides the last departure from Charles de Gaulle: about 22:25.

On 27 October 2026 the Orlyval closes at 21:00 for track works; the last way to Orly that evening is metro line 14 from Paris.

Orlyval calls at Orly 1-2-3 first and Orly 4 a minute later; get off at the terminal you need.
