End of direct bus service to Paris airports
 

Orlybus service was canceled when metro line 14 was extended to Orly airport.
Now RATP advises that Roissybus will be canceled next spring, not waiting for the grand opening of CDG express (2027?). It currently connects Opera to CDG but RATP claims that traffic jams on A1 impede travel time.
It seems that a new bus service between CDG and St Denis Pleyel will operate, connecting with lines 13 and 14 for Paris. No details so far if it will be a non stop service or "a la mode" current services that visit suburbs
NB: I did not count Beauvais as a Paris airport. I guess that there are still bus services between Porte Maillot and Beauvais despite the works around the bus station
