If you are going on vacation in Tarifa, you should consider that the nearest airports are 160 kilometers away (Malaga) and 200 kilometers away (Seville).
Malaga is a fairly large airport, which is the fourth largest in terms of passenger traffic in Spain. You can view flight schedules at Malaga Airport on its official website.
