I just want to say I did my ATPL in distance learning in Poland where the exams fees for all 14 subjects, including re-takes, are only 250 euro and don't even need to make any booking. You just show up when the session is open and tell the lady what exams you want to take.
You could do your ATPL theory with any school and do the exams in any other country.
I went with Bartolini and they use Bristol.
