I'm afraid not....

Roissy is 26 km away from downtown Paris (let's say Notre-Dame), while Orly is barely 16 km away...
For instance a regular cab ride from downtown to CDG will be around 45/50 Euros, while it will be around 30 Euros to get to Orly.
Of course I am not taking into account the usual traffic jams (on both motorways)...


In order to answer the original query, I found on the Aeroports de Paris web site the following mention: The G7 taxi company also features a Limo service : Aéroports Limousine Service Reservation : 01 40 71 84 62
Could be a good idea to contact them.
However I did not find any mention of an email address...
