Ah ,forgot about that reclearing security isn't necessary coming from the US. In that case, it's just off to the transfer desks.
Although I'd rather exit the terminal and go for a potty break / walk after the transatlantic flight. Schiphol does not have airside pet relief areas (no, the
airport park is NOT a pet relief area!). This is doable on a layover of 90 minutes or more.
