Look carefully at the
BlacklanePass wording - IMHO 'expedite' for $200 on AMS arrival consists of accompanying you to immigration but once there I don't recall a Priority line - other than Privium which was correctly excluded by UKtravelbear since it requires pre-registratiion.
Same vague 'expedite' offer on other sites even like
Schiphol's Meet & Assist which at least gets you a buggy ride
