 The only exceptions are Noctilien night bus lines, Orlybus and Roissybus airport bus shuttles (which do not accept the tickets and require a separate fare), and lines 299, 350 and 351, which can require up to three tickets for a journey.This only applies if the ticket is purchased in advance, as tickets purchased on board the bus do not permit any transfers.Noctilien night bus can be used with standard Ticket "t+"; however, if the trip exceeds a certain length, up to 4 tickets can be required.
