Q: Can I purchase a T-Casual Ticket on the Bus with Cash?
Important update: On 01 January 2020 the T10 ticket transport ticket was discontinued and replaced by the T-Casual ticket. Click here to learn more.
A: You cannot purchase the T-Casual Ticket on the bus or once you are on any other form of transport. You need to purchase the card before you get on the bus from any metro station, or if you arriving from the Airport you can buy it at the entrance to the RENFE train at T2B terminal.
A better alternative to the T-Casual might be the Hola Barcelona Travel Card that offers unlimited travel on Barcelona public transport. You won't have to worry about the number of journeys you have left on your T-Casual Ticket or about purchasing a new one that you might not entirely use. With the Hola Barcelona you can travel unlimitedly and worry-free while saving money.
