To see all your segments, look on the site of the carrier you booked with (AF). Look it up using either your confirmation number or your ticket number, not your frequent flyer number. Ticket number is the most reliable.

You can look up your reservation on the Delta site, however it might not show all segments, only the Delta flights. Same thing happens in reverse when you book on DL and have flights on AF... The AF site often doesn't show the Delta segments, especially if they're first.
