The best way of transportation in Barcelona is the metro. The single ticket costs 2.40€. The "T-casual" card is an individual travel card valid for 10 trips and its price is around 11.35€. The tickets can be bought inside the metro stations, in the automatic machines (English language and credit card accepted). However the T-casual card cannot be used for the metro stops Aeroport T1 and Aeroport T2. You would need to buy a special Airport metro ticket if you want to use the metro to get to and from Barcelona airport.
