Arranging transportation card was quite easy and fast. There are a few options of tickets you can choose from, depending on your age. If you are under 26 it’s best to take a student 1/3/6 months or yearly card, over 26 the best option is flying card. Both options are super cheap and include all Prague’s means of public transport! I do advise you to buy the card either before or after first week in October to avoid long queuing and have your photo ready.
