Thanks for the info and ideas. My reasoning behind the question was yes, directed towards how an airline might consider someone and where they have done their ATPL's.
I have chosen to do the ATPL's through Pan Aviation in Dublin who is associated with Bristol Groundschool, though it will be an IAA ATPL I will have issued rather than a UK. This is where my confusion stemmed -- would it matter to an airline, an IAA fATPL or UK fATPL.
Thanks again for the help.
