Do you know if I buy a 15 day travel pass at the airport, do I have to validate it somewhere? How do I do this, if so? Thank you
I suppose you mean the 15 days (360 hours) ticket for Prague transport. You have to check it in the first bus/tram etc. you use, and the 360 hours validity interval starts at this moment. There is a special printing device(s) in each bus, which will print the date and time on your ticket. The same devices are at the entrance to metro stations.
