UX has a very limited presence in SVQ. I think that they are just serving the Spanish islands from there. They are also code-sharing on Spanair metal (BCN and may be other destinations).
With the logical exception of IB, most legacy carriers have pulled-out or drastically reduced SVQ, while charters and low cost carriers have literally invaded the place.
I don't know if it could be a viable option for the OP, but UX is flying from AGP to CDG (AF code-share).
