I think it says in the small print on the Jerez brochure something along the lines of the minimum age being 18 - dont know if its something to do with the minimum age for a CPL issue being 18 or what - really must go back and study some more air law!
Anyways, bide your time and enjoy being too young to start pal, it all gets rather busy when you do start!
All the best.
