Q: Please can you confirm if we need to have one T-Casual each as this would be expensive could we share the card because it would be more economical.
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: The T-Casual ticket cannot be shared with your group members on the same journey. However you can give the card to someone and they can use it on a separate journey from the one you are taking.
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.
