Well to get an Netherlands Antilles ATPL (B1) license, you will need to complete your ATPL written exams with are even harder than the JAA written exams ,let alone the FAA ( 8 subjects) almost all open questions and the exams can only be taken twice during the year.
Also you will need a type rating on an A/C heavier than 20000 kgs
With an FAA ATPL you only get an B3 CPL
best thing to do is to get your JAA licence
