RER BorRER B and Orlyval to Orly?

The short answer

These do not go to the same place, so price is not the comparison. The RER B reaches Gare du Nord and Châtelet–Les Halles, on the right bank; the RER B and Orlyval to Orly does not. The other airport, not the city. For a connection between the two; for central Paris take the RER B to Gare du Nord or Châtelet–Les Halles.

The RER B is quicker: 35 min against 1 h 08. The RER B and Orlyval to Orly varies between 65 and 79 minutes.

RER B: 04:50–23:50. RER B and Orlyval to Orly: 05:05–22:24.

Buy the EUR 14 airport ticket, not the EUR 2.55 one. The ordinary Métro-Train-RER ticket and the Navigo Jour are sold everywhere and are not valid to or from the airport; the machines at the airport sell the right one.

The EUR 14 ticket is void on every bus, including the night bus. If you land after the last train, the N143 needs a separate EUR 2.05 Bus-Tram ticket.

Two trains, two speeds: trains with two intermediate stops reach Gare du Nord in 31 minutes, all-stations trains in 35 to 40. Both cost the same; take whichever comes.

On most weekday evenings this autumn the last train from the airport is 22:49, not 23:50, and the replacement bus takes 80 to 90 minutes to Gare de l'Est from the Roissypôle bus station, not from the platforms. Check the day before relying on a late train.

A Navigo Easy card cannot hold an airport ticket and a Métro-Train-RER ticket at the same time. If yours already has ordinary tickets on it, buy the airport ticket on your phone or on a second card.

Two children aged 4 to 9 travel for the price of one adult; under 4 is free. There is no family or group price beyond that.

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.
