Flypuppy,
You have to do both the flying and the ground studies at a FTO authorized by the same aviation authority. The school in Jerez is CAA/JAA so you can finish your CPL there if your theory was done in the UK. What you cannot do is switch to a school authorized by the DGAC, even if it is JAA. This info was given to me by the CAA a few months back. <img src="smile.gif" border="0">
