Hi Bop
1- When my mob lost the plot and decided to unleash me on unsuspecting humanity as PIC I was sent to the hell-box for my command/ATPL checkride, in other words you can hop into the sim for a combined captains' checkride and JAA ATPL checkride, thereafter the linechecks etcetc.
2- Have also heard that some companies advertise for ... (insert country) JAA ATPL holders. Not a problem, when I was based in Europe employed by another branch of our company I investigated this with the authorities, apparently a JAA ticket-holder can change the country who administers his/her licence when employed by a company in that country, e.g. you gets a job with a french employer, you changes your UK JAA ATPL to a French JAA ATPL, if you want to. Knowing the JAA and the EU this is probably already outdated info, was true about 2 years ago.
Hope this helps, best of luck...
