10/4 - submitted application for a child at the local post office. Regular processing, nothing expedited.
10/8 - check cashed
10/9 - "in process" online, Boston (10...)
10/28 - "approved" online
11/03 - passport in the mailbox, priority mail (never saw the tracking number online, also not in the Informed Delivery, I wonder)

Past experience suggests there is no difference between expedited and regular service, this was no exception.
