I believe that the book of tickets you buy for public transportation in Paris are good for one hour (you can change from metro to bus or vice versa for one hour). Question is about the details. If you use the pass at say 10:00 for a bus, and then get on the metro at 10:59, is the pass good until you reach your destination or will it expire one minute after getting on the metro?
Thanks in advance
