Paris Metro - One Day Pass?

Question

Are One Day Metro Pass in Paris available that can be used to travel from 1, Av De La Republique, 93177 Paris Banelot to CDG airport?

Answer 1

There is no such city as Paris Banelot and no such postal code as 93177 (I checked on the French postal website) so I'm going to disregard that and assume that you will be traveling one way from somewhere in zones 1 or 2 to the airport.  Given that, it is best to just buy a one way ticket, which costs about 8 euros.

Answer 2

CDG airport is in Zone 5. So any pass you buy with the intention of traveling to CDG must be for zones 1-5.

The Mobilis (a one day pass that is explained only on the French language portion of the RATP site) for zones 1-5 costs 12.30 euros. So unless you are making a round trip to the airport or traveling around Paris before heading for the airport the simple one way fare on the RER commuter rail or the one way fare on the Rossybus (8.5 euros) will be cheaper.
