What is the difference between the Mobilis Day Pass and the Navigo Day Pass? I can't find a meaningful difference between the two; they both cost the same as well. Thank you!
There used to be a difference (Mobilis was previously not valid for Airports and was priced less than Navigo Day Pass), but the RATP has normalized the two to be exactly the same in terms of coverage and prices. The sole difference I can see now is that the Mobilis can be purchased as a single use paper coupon-like ticket, not requiring a Navigo card or Navigo Easy card to put it onto, which the Navigo Day Pass requires.
