This is "little" Girona airport, which up to eight years ago was closed for four months of the year as "too little traffic to warrent it being staffed".
Ryanair also fly into Barcelona and Barcelona-Reus, so heaven knows how many people they carry in total to the Costa Brava each year.
I think you'll find that neither of the "Barcelonas" that they fly to are what the rest of the world understands as Barcelona.
