Best way to get to Paris via airplane from San Sebastian

Hey everyone,

I'm staying in San Sebastian this summer and need to find a way to get to Paris. I've looked, and have the option of either going to Biarritz airport or Bilbao Airport to get to Charles de Gaulle. What is best? Both flights leave at around 1pm giving me enough time from the airport to either Biarritz or Bilbao Airport. What's the best option in terms of the convenience to get to either place from San Sebastian? Also, what is the best way to get from San Sebastian to that airport?

Thanks!
