When travelling by private car makes sense
Your flight arrives in Barcelona without a convenient connection to ALC; you are travelling as a group or carrying substantial luggage; you arrive at a time when flights south are not available; you prefer not to fly; you would like to stop along the Mediterranean route, for example in Valencia or Peñíscola; or you need a door-to-door journey without changes, which can be useful for older passengers or travellers with reduced mobility.
