UK fATPL or Spanish fATPL

[The Original Jetpipe]

Please can someone explain or tell me where I can find the major differences between a

United Kingdom issued CAA/JAR fATPL license and a Spanish issued CAA/JAR fATPL license.

I have been unable to find any major differences in the courses. However what do the UK airlines want to see on your C.V.

Thank you in advance of any replies
