I've just checked - it is one ticket now, except on the Balabus and four
other lines, the 221, 297, 299, 350 & 351. Don't know where those run,

change bus without another ticket.

Thank you for that. I haven't used a bus in Paris for many years,
because of the (then) ticketing regime, so I hadn't noticed the change.
On my next visit I will try to wean myself away from the Metro.

If you read French, there's a very interesting history of the Paris bus
network on http://tinyurl.com/3rhfv which says, among other things, that
the 1970s were really the nadir of the network, and that they have done
a great deal to improve things since then.
