Cannot be specific but the standard approach to delays are this:
On the day: all flights carry their regular pax and those delayed from previous flights fit in as and when. Some will accept a long delay (days) before boarding; some will pay an upgrade to get away; some will find alternate routings c/o the carrier or themselves; some will just be no-shows.
So, if you are booked to travel on a particular day and the flight is not canx - then get there SUPER EARLY as you have a better claim on the seat than those delayed.
